1. Introduction
The purpose of this document is to assist partners in correctly configuring Cisco Unified
Workforce Optimization (WFO) systems, including one or both WFO applications: Call
Recording and Quality Management (MR) and Workforce Management (WFM).
Correct configurations will ensure:

Accurate customer quotations

Successful customer deployments

Continued customer satisfaction as the configured system provides both the performance
and capacity to meet customer needs
A step-by-step methodology is employed to guide partners through the process of identifying the
necessary hardware and system software components required for their customer’s specific
situation.
Additional information and assistance is available via the following sources:

Cisco Unified Workforce Optimization web site
http://cisco.com/en/US/products/ps8293/index.html
o Product collateral material – data sheets, bulletins
o Product documentation – install guides, release notes and service information for
each WFO application


Note: Prior to the 8.0 release references to the entire product or core services of Call Recording
and Quality Management (MR) was typically referred to as QM. This reference in regards to
core services has now been replaced by MR but some historical references to QM may still exist
within this or other documents. The acronyms should be considered equivalent.
2. About Cisco Unified Workforce Optimization
Cisco Unified Workforce Optimization (WFO) for Unified CCX is a full-featured solution for
optimizing performance and quality and is an integral component of the Cisco Unified
Communications System. The WFO suite provides two solutions: Workforce Management
(WFM) and Call Recording and Quality Management (MR).
-
Workforce Management allows for forecasting and development of schedules for agents
across multiple sites and channels. It also provides real-time dashboards, enabling
6
supervisors to track key performance indicators and manage agents’ adherence to
schedules.
-
Call Recording and Quality Management is a voice and screen recording, compliance and
evaluation solution for agent performance optimization and dispute resolution.
The following architecture diagram shows the overall service communications medium between
the WFO solutions and Unified CCX.
3. User Licensing Considerations
3.1 Named or Configured Versus Concurrent Users
Concurrent users are the basis for Cisco Unified Contact Center Express (Unified CCX)
licensing and are generally defined as the maximum number of users which will be logged into
the system at the same time, or concurrently. Cisco charges and enforces WFO application
software licensing based on the number of “named” users. Ciscodefines “named” users as all
users of the application who have been configured and licensed within the administrative tool.
The term configured is sometimes used in place of named when referring to application users
and the terms are considered synonymous. Named users include all users who are being recorded
or scheduled plus all supervisors, managers, evaluators or others with usernames for accessing
application data.
7
3.2 Who Needs to be Licensed?
Active product users with login names and agents who are scheduled by the WFM application or
users recorded by the MR application all require user licenses. It is not required to have WFO
licenses for all agents within the ACD, just ones actively using the system. Each WFO
application can also license a separate subset of agents or users, it is not required the same users
be licensed for both applications.
3.3 Compliance Recording Users
Beginning with QM 2.7.2 a third user licensing option entitled Compliance Recording, CR, was
added to the existing QM (Agent audio recording and quality evaluations) and AQM (QM
functions plus screen recording) user license types. The Compliance Recording license enables
selective or 100% audio recording of calls for agents or knowledge workers. Knowledge
workers are defined as any Cisco IP telephony user of a phone supported through Cisco Unified
Communications Manager. In addition to 100% call recording the compliance recording license
also enables the user to do call search, playback and export functions within the Call Recording
and Quality Management Search and Play application. For the purposes of system configuration
CR licensed users represent the same load as QM agent users and together these are two types
are just referred to as users. AQM users represent an additional system load for the screen
recording process as delimited in the system capacity tables.
3.4 MR Systems with Mixed License Types
Beginning with QM 2.7.2, support was added to MR to allow a single system to simultaneously
support all three license types – QM, AQM and CR assigned to different users of the same
system. User privileges like evaluations or screen capture are restricted to users based upon their
assigned license type.
3.5 Managing User Licenses
The MR user administration tool provides a means to license and un-license users. Un-licensing
previously-licensed users allows customers to reuse the named user licenses for users who have
become inactive, for example users who have left the organization. Un-licensing a user will
remove them as an active login but will not affect their preexisting recordings or database
information within the WFO applications.
4. WFO Application Server Software
4.1 Operating System Requirements
Each WFO application server requires Microsoft Windows Server operating system to be
provided separately by the partner or customer. Both WFO applications can use Windows
Server 2003 R2 Standard edition and MR 8.0 also can use Windows Server 2008 R2 Standard
(32 bit edition). The most economical configuration of this is to purchase with 5 CALs – client
access licenses. Since WFO application users do not directly access or use the Windows server
software, additional client access licenses for WFO application users should not be required.
Additional details about client access licensing for Windows Server 2003 can be found at:
http://www.microsoft.com/windowsserver2003/howtobuy/licensing/caloverview.mspx .
8
Although Windows Server 2003 has reached end of sale it is still available by purchasing Server
2008 and exercising downgrade rights to Server 2003. See
http://www.microsoft.com/windowsserver2008/en/us/downgrade-rights.aspx .
4.2 Database Requirements
Each WFO application – MR or WFM – requires one database instance hosted on Microsoft
SQL Server 2005 or in the case of MR 8.0 and above SQL 2008. Partners or customers must
provide this separately for the WFO applications. WFO application deployments can meet this
requirement in two ways:
1) Internally, by installing and hosting SQL Server 2005 standard edition on the application
single server or on the database server within multi-server configurations
2) Externally, by creating an SQL database instance for the WFO application(s) on an external
SQL server
Generally, systems will use the internal option but may consider the external option to reduce
database licensing costs – particularly if the customer already has an enterprise-licensed SQL
server capability or if the enterprise desires to share SQL licensing between WFO and other
applications.
4.2.1 SQL Licensing Guidelines
Acquiring and properly licensing the SQL database used by the WFO application(s) is the
responsibility of the deploying partner and the end customer. Cisco provides the following
guidelines as a convenience for our partners but cannot guarantee the accuracy of the information
nor should this be construed as a replacement for the partner’s due diligence in understanding
software licensing terms and how they apply to a specific implementation.
4.2.2 Guidelines for an Internal SQL Database Licensing
4.2.2.1 Processor verses CAL Licensing
WFO applications require Microsoft SQL Server 2005 Standard edition. Calabrio’s
interpretation of Microsoft’s client access licensing (CAL) terms is that each WFO user would
require a CAL. Since the cost of SQL server plus 30 or more CALs would be more expensive
then the cost of a processor license, Cisco recommends using the processor license which
eliminates the need for user-based CALs. Additional information on Microsoft SQL licensing
can be found at: http://www.microsoft.com/sql/howtobuy/default.mspx .
4.2.2.2 Multiple Processor SQL Licensing
If SQL is hosted on a server with multiple physical processors, like an MCS 7845 or equivalent
server, then Calabrio’s interpretation of Microsoft SQL licensing terms is that multiple SQL
processor licenses would be required.
4.2.2.3 Multi Core SQL Licensing
If SQL is hosted on a single physical processor with multiple cores, then only a single SQL
processor license is required. See details at
http://www.microsoft.com/sql/howtobuy/multicore.mspx .
9
4.2.2.4 Virtual server, aka VMware, SQL licensing.
Virtual servers are now an approved WFO hardware configuration, with the following caveat
from the Product Install Guide:
MR hosted on VMware was only tested for functionality. MR was not tested for performance or scalability
in the VMware environment. Due to the many VM configuration factors and possible performance
impacts of additional hosted virtual servers, determining the actual server performance results under the
VMware environment is the customer’s responsibility. If a problem occurs, the customer may be required
to shut down other VM sessions or reproduce the problem in a non-VMware configuration to assist in the
isolation of the issue. Support for performance and scalability issues are limited to server-based
deployments.
The following link explains virtual server licensing for SQL
http://www.microsoft.com/sql/howtobuy/faq.mspx .
4.2.3 Guidelines for an External SQL Database
When using an external database, ensure the database server has additional capacity to handle the
WFO application load. If sharing a SQL database between the WFO applications, MR and
WFM, Cisco recommends the SQL database be hosted on a dedicated SQL server on a platform
equivalent to the largest platform recommended for either of the WFO applications.
5. Server Hardware Configurations
5.1 Matching the Hardware to the Number of Users
The server configuration recommended is directly dependent upon the expected number of
named and concurrent users of the application. The maximum recommended users are based
upon scalability testing to ensure a reliable and responsive system for the customer. Partners
should take into account not only the initial number of users within the deployment but also
consider potential growth factors and size the system to accommodate potential expansion of the
user base, at least for the first year after deployment.
5.2 Server Hardware Specifications
Application server recommendations are based upon a few specific Cisco MSC H2 server
configurations. Partners may substitute different hardware provided it is equivalent or better
then the target MCS server. Because Cisco may update the MCS server configurations from
time to time, partners can use the following link to the server specification in lieu of the
specifications themselves. Partners should verify their proposed hardware is equivalent to the
Cisco MCS xxx H2 server configurations when designing a WFO system to ensure they are
deploying equivalent or better configurations. Cisco MCS server configurations are listed at
http://www.cisco.com/en/US/products/hw/voiceapp/ps378/prod_models_home.html
5.3 Workforce Management Hardware
5.3.1 Workforce Management Single-Server Hardware Configuration

5.3.3.1 WFM Capture Service
The Workforce Management Capture Service watches for historical call data reports created by
the Workforce Management OOC (Odysoft ODBC Collector) Service. When the Workforce
Management Capture Service detects a new report, it sends a compilation request to the
Workforce Management Compile Service.
5.3.3.2 Compile Service
The Workforce Management Compile Service listens for compilation requests from the
Workforce Management Capture Service. The Workforce Management Compile Service can
compile historical data for agents, services or teams by day, week, month, or year, for use in
forecasting and scheduling. When requested by Capture Service, compiles historical data by day,
week, month.
5.3.3.3 OOC Service
Every 30 minutes, the Workforce Management OOC Service collects all of the call data for the
preceding 30 minutes from the ACD database using the Open Database Connectivity (ODBC)
interface. The Workforce Management OOC Service then writes the call data into historical
reports.
13
High availability (HA) configurations can use multiple data sources. The Workforce
Management OOC Service always connects to the first node, however, and fails over to the
second node only if the first connection fails.
5.3.3.4 Request Service
Processes user requests to generate forecasts and schedules
5.3.3.5 Adherence (RTE) Service
The Workforce Management RTE (Real Time Engine) Service uses the Advanced Contact
Management Interface (ACMI) protocol to get real-time information on agent states from the
Unified UCCX server. WFM displays agent state information in the Supervisor Adherence
dashboard.
5.3.3.6 Sync Service:
The Workforce Management Sync Service retrieves and processes user configuration data, such
as skill group configurations, team configurations, and agent configurations from the ACD.
5.3.3.7 Tomcat Service
Provides web services for WFM browser based clients.
5.4 Call Recording and Quality Management Hardware
5.4.1 Recording Architectures: Desktop, Server (SPAN) and Network
Call Recording and Quality Management, MR, offers three different recording architectures that
can be used on their own or together in a single deployment, depending on the customer’s needs.
5.4.1.1 Desktop Recording
Desktop recording utilizes the same capture technology as Cisco Agent Desktop (CAD). The
user PC’s Network Interface Card (NIC) is placed in promiscuous mode, allowing the Desktop
recording service to copy the RTP voice stream packets as they are transferred to the IP phone.
The service then caches the recordings locally on that user’s PC, and then compresses, encrypts
and uploads the recordings to the MR storage device at a time designated by the administrator.
The fundamental benefit that this architecture provides is being able to easily record users in
multiple physical locations. Desktop recording does not need recording servers at every location
in order to do the recordings, and the solution scales up with the number of users without
requiring additional recording servers.
To enable the Desktop recording service to capture the call, the endpoint PC and phone must be
configured as shown in the diagrams below.
14
Notes:
1. Certain Cisco phones such as the 79xx phones must be configured to span ports in the
Unified CM administrator in order to pass these packets on to the agent’s PC
2. The complete list of Cisco IP phones that support endpoint recording is located in the Quality
Management Installation Guide
5.4.1.2 Server Recording (SPAN)
There are certain situations in which the customer is unable to use endpoint recording:
 Customer uses a thin-client environment such as Citrix or Windows Terminal Services
 Customer uses IP Phone agent
 Recorded user’s PCs is not available or doesn’t meet the requirements for endpoint
recording
To address these environments, Call Recording and Quality Management include a server
recording option, again, similar to Cisco Agent Desktop. Server-based recording relies on the
network switch interconnecting the phones support and be configured for Switched Port
Analyzing (SPAN) sessions, where user phones are attached to the designated source ports, and
the destination port routes the packets from those source ports to a server running the Server
Recording services.
For a detailed explanation of server-based recording, as well as some example configurations,
please see the Voice-Over IP Monitoring Best Practices Deployment Guide for CAD 6.0/6.1,
located here:

(or search Cisco.com for ‘monitoring best practices’)
Please disregard any server capacity numbers stated in the Best Practices guide and use the
capacity numbers in the Hardware Configuration sections below.
For more detailed information about configuring Cisco Catalyst switches for SPAN sessions,
please see the Catalyst Switched Port Analyzer (SPAN) Configuration Example (Document ID
10570):
http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c61
2.shtml
15
5.4.1.3 Network Recording
Network recording is similar to Server recording in that multiple phones are recorded via
services running on the MR base or an external recording server. The primary difference is that
the Network recording server receives the IP telephony packets from the IP phone devices built
in bridge under control of Cisco Unified Call Manager, CUCM, in lue of a SPAN port
connection to the switch. For more information see the “Monitoring and Recording” section of
the Cisco Unified Communications Manager Features and Services Guide available at:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_1_2/ccmfeat/f
smr.html
From a scalability standpoint network recording shares the same capacity tables with Server
recording with the exception that network recording adds a live monitoring function.
5.4.2 MR Single-Server Hardware Configuration; Desktop or Co
Resident recording services
The MR single-server configuration has all MR services installed on a single MCS-equivalent
server including the Server and/or Network recording services running co resident on the single
MR server. The specific model required is defined by the maximum number of named,
concurrent or co-res recording users as shown in the table below:

 Up to 300 users could be on the system concurrently
 100 QM or CR licensed users need voice only recording simultaneously using server or
network recording
Based on the above table, this customer should use an MCS 7825 for the main MR server and an
MCS 7835 for the Recording server:
 Customer has a total of 400 named users, with up to 300 recorded or logged into the MR
desktop concurrently. The MCS 7825 allows for up to 900 named users and 300
concurrent users.
 Customer needs to record up to 100 concurrent voice-only (no screen) calls, via Server
based recording. The MCS 7835 hosting server based recording supports for up to 200
voice-only concurrent recordings

5.4.5 Calculating Quality Management Contact Storage Capacity
In addition to the normal disk storage for the operating system, SQL database and MR server
software, MR deployments must also plan for storage space for the recorded contacts. The total
amount of storage required is based upon the cumulative time and types of recording to be stored
on the system. Calculate the cumulative storage requirements using these formulas:
Recorded minutes/day = average call time * # calls/day * # of users
Recorded minutes in MR = Rec minutes/day * work days/user/month * months to save
Voice Storage = Recorded minutes * 0.12 MBytes/min
Screen Storage = Recorded minutes * 1.2 MBytes/min
Note: The screen storage rate represents the average recording rate over thousands of contacts.
The rate for individual contacts may vary with the amount of screen activity.
5.4.6 Quality Management Contact Storage Example
Average call time = 330 seconds or 5.5 minutes
# calls/day = 40
# of users = 60
Recorded minutes /day = 5.5 minutes * 40 calls * 60 users = 13,200 minutes
Average work days/user/month = 21 (full time, 5 days per week)
Months to save = 2 (Saving for 60 days through quality evaluation & review cycle)
20
Recorded minutes in MR =13,200 minutes/day * 21 days/month * 2 months = 554,400
min
Voice Storage = 554,400 minutes * 0.12 MBytes/minute = 66 GBytes
Screen Storage = 554,400 minutes * 1.2 MBytes/minute = 665 GBytes
Note: A single system may have multiple groups of recorded users with variations in recording
rules or retention periods so this calculation may need to be repeated for each group and the
results summed together to get to total storage requirements.

5.4.8 Options for Recorded Contact Storage
MR supports a variety of contact storage options including local hard disk drive (HDD), network
attached storage (NAS) or storage area networks (SAN) by allowing the installer to specify the
storage location for voice and screen recordings as server and pathname during install or change
the location by moving the existing contacts and running the post-install process to specify the
new contact storage location. It is recommended to use external enterprise-class SAN or NAS
storage for critical recordings because of the additional fault tolerant options provides by these
storage architectures.
5.4.8.1 Local Storage
Contact storage can be hosted within the MR single server or on the Voice and Screen Storage
servers in the multi-server configuration. The storage used can either be a portion of the server’s
primary partition on the base disk(s) that came with the server or can be on a secondary partition
using additional drives added to the base server. In either case, it is recommended that contact
storage be provided on a RAID volume to protect the recorded contacts from drive failure. The
following table shows the base and expansion capacity of the Cisco MSC server configurations
recommended for MR deployments. It is from a worksheet within the storage calculator
worksheet described previously.

To calculate actual expansion capacity of servers fill in the yellow highlighted cells,
default values show the maximum potential capacity
* NOTE: Very large capacity disks may need to be purchased and supported outside of the Cisco channels
Notes:
The MCS 7835 provides the maximum expansion capacity for recording storage.
Popular expansion 2.5” drive capacities can be selected via a drop down in the Disk Capacity
column.
MCS 7816 base only provides a single 160 GB disk with no RAID protection for the primary
partition. It is recommended that disk expansion be done with an equivalent disk capacity,
binding the expansion drive to the base disk in a RAID 1 volume.
The base reserved system capacity is an estimate of the space required for the OS, database and
MR server application and may need to be adjusted for the actual server configuration.
5.4.8.2 Network Attached Storage or Shares
Configure the NAS or share to allow read and write access from the MR server and allocated the
required storage capacity to the share. Set the server and storage share location during MR
install to the server name and share to be utilized.
5.4.8.3 Storage Area Network (SAN)
Map a dedicated SAN volume to the MR server and create a file system partition on that volume.
Then setup the recording storage to point to the mapped drive or a share name within the
partition
5.4.9 Quality Management Backup CTI Services
QM 2.7 introduced a Backup MR CTI service option to provide redundancy for the
communications path for CTI events like ringing, answered, dropped between the Cisco Unified
Communications Manager, CUCM and the MR endpoint or Server based recording services. A
backup MR CTI service would be required for each primary MR CTI service, one of which is
required for every CUCM cluster covering recorded users.
22
Hosting the Backup MR CTI service requires a MCS 7825 server with Windows 2003 Server
with Service Pack 2.
5.4.9.1 Description of Backup MR CTI Service Operation
ACD







The base MR configuration includes a single MR server hosting all services. In order to
ensure the endpoint recording services continue operation through a MR server failure,
version 2.7 has introduced a redundant CTI service option. With the redundant option a
second MR CTI Service can be installed and configured on a separate server to ensure
CTI events are forwarded to the endpoint recording clients.
Then both MR CTI services will use the JTAPI link to Communications Manager which
can be configured with both primary (publisher) and secondary (subscriber) links to
Communications Manager.
The recording clients select which MR CTI service to use starting with the first service
and proceeding down the list until a connection is established. Once a connection is in
place the MR CTI service will register for the clients phone events with Communications
Manager via JTAPI.
When a ringing or answered event occurs recording is started.
If the recording client to MR CTI service connection is broken, the recording files in
progress are closed, file number 1 and the recovery process is started.
To recover the endpoint recording service then establishes a connection to the redundant
MR CTI service and if a call is in progress an event is forwarded immediately and the
endpoint starts a new recording, number 2. Therefore the contact recording capability is
maintained through failure of the primary CTI service. Once the service is restored the
endpoints will reconnect to the primary CTI service.
Additional Failback details. Once the Primary CTI service is back up, even if the
Secondary CTI service is running, we will connect back to the Primary CTI service as
soon as possible, which may be immediately or immediately after any active call is
23
disconnected. Our reason for going back to the Primary CTI service even when the
Secondary CTI service is running, is to minimize the case where a desktop recording
service is connected to the Primary CTI service and the server based recording service is
connected to the Secondary CTI service and they are both recording the same phone.
Staying on the primary CTI service also makes it easier to troubleshoot issues since only
one CTI service is in use at a time.

5.4.10.1 CTI Server
The MR CTI service acts as a bridge between the MR Recording service and the Cisco Unified
Communications Manager/CTI Manager. It sends events to the MR Recording service when the
status of monitored phones changes.
24
The MR CTI Service communicates with the CTI Manager using the Cisco JTAPI interface to
listen for phone events (it does no call control). The MR CTI Service forwards these events on to
the MR recording client for workflow processing.
When users that have been configured in MR log in to a PC with the recording service installed,
a message is sent to the MR CTI Service. The MR CTI Service in turn registers an event listener
with JTAPI and is notified when phone events occur. When the user logs off the PC, the
registration with JTAPI is removed for that user.
5.4.10.2 Sync Service
The MR Sync Service reads data from the Unified CCX system using an ODBC interface. It
maintains an ODBC connection with the UDB and runs queries every ten minutes and stores the
information on the MR Base server. The information that is read consists of:
- Agents
- Teams
- Supervisors
5.4.10.3 Desktop Recording Service
The Desktop Recording service is the end-point utility that enables the recording of user
contacts. It is resident on the user’s PC.
5.4.10.4 DB Cleaner Service
The DB Cleaner service purges records from the MR database and media files from the Voice
and Screen servers on a daily basis according to the retention times configured in MR
Administrator.
5.4.10.5 DB Proxy Service
The DB Proxy service is the single point of connection between users and the MR database.
5.4.10.6 Monitoring and Notification (MANA) Service
The Monitoring and Notification service monitors the MR system in real time and notifies
administrators via event viewer or email when problems occur. The problems that trigger
notification are selected in MR Administrator.
5.4.10.7 Tomcat Service
The Tomcat service web server hosts the MR Reports engine, File Transfer Servlet (FTS), Server
API engine, and Licensing engine.
5.4.10.8 Upload Controller Service
The Upload Controller manages the uploading of recordings and recording metadata to the Voice
and Screen servers.
5.4.10.9 (SPAN port) Monitor Service for Server-based Recording
The (SPAN port) Monitor service works in conjunction with the Network Recording service. It
monitors the destination port from the switch’s SPAN session for voice packets, and is
25
responsible for forwarding only the voice packets that match the packet filter. The packet filter is
constructed based on requests from the Network Recording service that keeps track of which
devices actually need to be recorded.
NOTE: The SPAN port Monitor service does not include the ability to perform live call
monitoring; live call monitoring is only available for users configured under Network recording.
5.4.10.10 Network Recording Service (for Server-based Recording)
The Network Recording service receives the packets forwarded from the SPAN port Monitor
service and writes those packets to recording files on the server’s hard disk.
5.4.11 Client PC Requirements for Call Recording and Quality
Management Applications and the Desktop Recording Client
These are listed in the MR 8.0 Installation Guide under Overview, Operating environment and as
such are not duplicated here.
6. Additional Considerations
6.1 Active Directory Authentication Option
When deploying in an AD environment, both MR and WFM servers should be a member of the
domain. The ACD server is recommended but not required to be a member of the domain – in
which case additional setup is required. See installation document for more details.
 When deploying WFO, a user must exist or be created on the Unified CCX server who
has read access to db_cra
6.2 WFM and MR Application Hardware Redundancy
 WFO products do not currently provide application server hardware redundancy.
However, note that both MR and WFM do support a redundant Unified CCX
environment and are able to switch to secondary/backup on failure of the primary Unified
CCX system.
 MR starting with version 2.7.2 does support a redundant CTI Service providing a
redundant path option for call event signaling between Communication Manager and the
MR endpoint or server based recording services
6.3 WFM and MR Application Server to ACD latency
WFM has no specific requirements for latency to the ACD. The primary feature of concern
would be the real time service, RTE, but WFM only uses this to get the agent state information
for displaying the agent’s status and tracking their schedule adherences. If it is acceptable for a
customer to have a latency delay in RTE display and adherence tracking then this latency will
not disrupt the functionality of the WFM application.
The critical network latency path for MR is for signaling CTI events. The network latency from
CUCM to the MR CTI service and on to the endpoint or server based recording service will
delay the start of recording by the sum of the latency time. Acceptable latency is at the
customers discretion as to the amount of recording delay is tolerable for their business needs.
Generally recording delays of fewer than one second have no perceptible impact to users.
26
As for the amount of MR CTI Event data transferred from the MR CTI service to the recording
services each event is approximately ~200 bytes per event with ~6 events per call (simple call
scenario) multiplied by the calls per agent and number of agents. MR CTI starts monitoring the
phone when the agent logs in during End Point recording (and removes registration on log out).
For Server-based recording it is constantly monitoring the phone. Agent login/logout has no
bearing on monitoring. Only phones configured for MR are monitored.
MR also connects with the ACD database for syncing purposes and the CUCM database for
SPAN configuration and the MANA CDR task that does call count comparisons. Latency is not
an issue for any of these connections.
6.4 Can WFM and MR deploy on the same server
Not currently as there are conflicts between some of the common services like Tomcat. This is a
recognized goal which is under consideration for future releases.
