During the Development of CallManager 5.0
Cisco’s Commitment to SIP Standard
• IETF co-chair of SIP, SIPPING, IPTEL, SPEECHSC, and
MIDCOM working groups. Several members of IETF
Internet Architecture Board. Founding member and
current board member of the SIP Forum
People
• Many SIP-related RFCs and interface drafts are authored
by Cisco employees . Over 30 Cisco engineers have
contributed to SIP and other standards
• Active participant in SIP Bakeoff and SIPit
interoperability events
• Solving the hard problems to deploy SIP networks
(QoS / Call Admission Control, Security, NAT
traversal), and delivering line-side feature parity
Contribution
• What we are delivering in CallManager 5.0 is
essentially a productization / manifestation of our
development efforts within the SIP standards
community over the last 3+ years

SIP Trunk Enhancements
• SIP Trunk interface
Originally available with Cisco CallManager 4.0
Upgraded to support RFC 3261
• Enhancements include:
Communications between CM Clusters
Interfaces to Applications—Video, MWI
REFER requests, 3xx redirection responses, out of band
DTMF negotiation to reduce MTP usage
• Technology Developer Partner Program testing
Testing of third-party applications connected to the SIP
Trunk is in process and expected at FCS
© 2006 Cisco Systems, Inc. All rights reserved.
Cisco Public
39
Supported SIP URIs
• Three types of routable addresses can be
configured for SIP trunks
Route Patterns Numeric route patterns (e.g. 9.@, 1XXX, etc.)
SIP Route
Patterns
Domain-style SIP route patterns (e.g. cisco.com)
Dotted-Decimal SIP route patterns (e.g. 10.1.1.0/24)
• Numeric route patterns can point to a route list, or directly to a
SIP trunk
• SIP route patterns must point directly to a SIP trunk. Cannot
point to a route list. Cannot use any other type of trunk (e.g.
H.323, MGCP, etc.)
• Note that endpoints registered to CallManager
must register numerical URIs, although dialing alphanumeric
or IP address based URIs is supported
