MG4 & MG8 Series Gateway Setup

Manual

Author: Zultys Technical Support Department

This document covers basic set up of the following Media Gateway models MG4/S, MG8/S,

MG4/O, MG8/O, MG8/SO (MG will designate any model in this series) in conjunction with the MX250 and MX30. This document is based on MG gateways with software revision

1.9.82.306 and MX system with software revision 6.0.

It is assumed the reader is familiar with creating Users, Devices, Assignments, SIP Servers on the MX system and is a current ZCSE Technician. Basic Telephony and Basic Networking is assumed as well. Consult “Media Gateway installation Guide” for installation procedure.

Consult “MG User Configuration Guide” for description of features not present in this manual.

It is strongly recommended that the MX is configured PRIOR to integrating the Media

Gateways to prevent the IP address of the Media Gateway being blocked by the MX.

MG Gateways must be configured with Microsoft® Internet Explorer®. At this time,

FireFox®, Safari® and other internet browsers are not supported by the current revision of

MG Gateway software.

2 Configure all ports on the MG

You MUST configure all ports on the MG, if you fail to configure all ports (even if you are not using them) the MG will continue to attempt to register, this action will cause the MX’s built in process to deal with registration attacks from unknown devices to block the IP of the MG itself.



Page 3 of 48


3 MX250/30 Setup

It is recommended that the MX have a generic SIP device created for each FXS

Port that is on the MG to register against. The Device ID used in the MX will be the phone number used on the MG for registration purposes; this configuration does not count against any licensing, as the MX is not licensed by registration.

3.1

Create Users

Create a user for each FXS (SLT) port of the MG gateway by logging into the MX

Admin UI and navigating to Configure | Users.

3.2

Create Devices for FXS/FXO Ports

Create a device for each FXS/FXO port of the Gateway by navigating to

Configure | Devices in the Admin UI. Each step is outlined below. Since you are creating Generic SIP devices no restart of the MX is needed. You will not be using the FXS configuration portion of the MX Admin UI, as the devices connected to Media Gateways are connected as SIP devices.

3.2.1

Create new Generic SIP Profile

Before creating devices for Gateway from the Manage Device screen click the

Profiles button, and create a new Generic SIP profile.



Page 4 of 48


From the dropdown select Generic SIP device, and give the profile a unique name.

Click the OK button.



Page 5 of 48


Recommended Settings:

 Sends SIP Registration

 G711 Codec (G729 is optional)

 Send Syslog event when device is not registered with the MX

 Send unsolicited NOTIFY for Message Waiting Indication if device does not Subscribe to MWI service

Click OK.

3.2.2

Create Devices

Create the same number of devices the gateway can support. By default the gateway will register ALL ports, even if not being used. The device ID’s created here should be used in the “phone number” field on the MG8 for registration.



Page 6 of 48


 Select Generic SIP device

 Add all available ports that are supported by the device

 Click Next

 Select the Profile created

 Device Prefix will be the starting digits of the device name (in this example we are creating device names of 10201 to 10204).



Page 7 of 48


 SIP proxy Password is optional o The password is required for each device if the MX configured to have ‘Authenticate Managed Devices’ under ‘Provision/SIP and RTP’

 Start Number (1 in this example)

 Click Finish

3.2.3

Assign Users to devices

Assign users to the devices.



Page 8 of 48


We recommend to assign users to the devices associated with FXS ports of MG only.

4 Connecting the Computer to MG Gateway

To configure the MG Gateway, use the web interface.

Use the Ethernet cable that comes with the system to connect MG to the network

By default the MG8 uses DHCP and can accept the IP address from DHCP automatically. If there is no DHCP server on the network, you can use factory default IP address of 192.168.2.218. After the MG8 is started (when leds stop flashing), it will repeat the IP address to the first off-hook user; in addition, you can dial ## from any analog phone connected to the FXS Ports to have the MG play its IP. If there is only FXO ports use external call and dial ## after been connected.



Page 9 of 48


From the PC that is on the same network as MG8, open Internet Explorer, no other browsers are supported at this time. Enter the gateway IP address in the

Address field (for example, 192.168.2.218). On the login page enter the gateway password (the default password is voip, which can be changed on the page Changing Password), and you enter the web configuration interface.

6 Basic Settings

Basic settings are where you set the IP addressing and SIP Registrations settings. SIP registration settings for the FXS/FXO port MUST be set LAST, to prevent the MX from blocking the IP address of the MG8. If the IP address is blocked by the MX (a syslog event will be generated) you must restart them MX to remove this block.



Page 14 of 48


6.1

IP addressing

Click on the Basic button and then click on the Network link.

Recommended Settings

 Host Name: Optional to change from the default

 IP Address assignment: Fixed

 DNS: Enabled

 Primary Server: Populate with correct server

 Secondary Server: Optional

 SNTP: The IP of the MX

 Time zone: Select appropriate Time Zone

Requires a system reboot, or you can make all the changes first and finish with a system reboot at a later time.

6.2

System Settings

Click the System link.



 Hook-flash handle: Internal

 DTMF: RFC 2833 (required, MX only supports RFC 2833)

 2833 payload type: 101 (required, or DTFM may not function)

 Codec: G729A/20, PCMU/20 o If you are using the MG for faxing, you MUST use PCMU/20 ONLY

 The rest can be left Default



Page 16 of 48

 Click Submit, and requires a restart.


Name Description

First digit timer If a subscriber hasn’t dialed any number within a specified time by this parameter after offhook, the gateways will consider that the subscriber has given up the call and prompt to hang up in busy tone. Unit: second;

Default value: 12 seconds.

Inter-digit timer If a subscriber hasn’t dialed the next number key from the time of dialing the last number key to the set time by this parameter, the gateways will consider that the subscriber has ended dial-up and call out the dialed number. Unit: second; Default value: 12 seconds.

Critical digit timer

This parameter is used with the "x.T" rule set in dialing rules. For example, there is "021.T" in the dialing rules table. When a subscriber has dialed 021 and hasn’t dialed the next number within a set time by this parameter (eg. 5 seconds), the gateways will consider that the subscriber has ended dial-up and call out the dialed number 021.

Unit: second; Default value: 5 seconds.

Codec

Hook-flash handle

Codecs methods supported by the gateways include G729A/20,

G723/30, PCMU/20, PCMA/20, iLBC/30 and GSM/20 (as shown in table 2-5). This parameter must be set due to no default value.

Several encoding methods can configure in this item at the same time, separated with “,” in the middle; the gateways will negotiate with the platform in the order from front to back when configuring the codec methods

The gateways provide the following processing modes after detecting hook flash from subscriber terminals: processing the hook flash internally; transmitting the hook flash to platform with RFC 2833, and transmitting the flash-off to platform with SIP INFO.



Page 17 of 48


Name

2833 payload type

Description

DTMF method Transmission modes of DTMF signal supported by the gateways include

Audio, RFC 2833 and SIP INFO. The default value is Audio.

Audio: DTMF signal is transmitted to the platform with sessions;

SIP INFO: Separate DTMF signal from sessions and transmit it to the platform in the form of SIP INFO messages;

RFC 2833: Separate DTMF signal from sessions and transmit it to the platform through RTP data package in the format of RFC2833.

Used with “RFC 2833” in the DTMF transmission modes. The default value of 2833 payload type is 100. The effective range available: 96 ~

127. This parameter should match the setting of far-end device (eg. platform).

DTMF on-time This parameter sets the on time (in ms) of DTMF signal sent from FXO port. The default value is 100 ms. Generally, the duration time should be set in the range of 80 ~ 150 ms.

DTMF off-time This parameter sets the off time (ms) of DTMF signal sent from FXO port. The default value is 100 ms. Generally, the interval time should be set in the range of 80 ~ 150 ms.

DTMF detection threshhold

Minimum duration time of effective DTMF signal. Its effective range is

32-96 ms and the default valie is 48 ms. The greater the value is set, the more stringent the detection is.

Trunk ID

Description

Select a trunk line required to configure. “FXO-n” corresponds to the “Line > FXO phone Number ID n”. Copy the configuration of

“FXO-n” for selected line to “FXO-n+1”~“FXO- m” by clicking

“Batch”, where n indicates the current selected trunk number and m indicates the total number of trunks.

Phone number

Registration

Display device ID associated with the trunk set in “ Line > FXO phone Number”

Select if this trunk registers with the SIP registration server. By default, this is selected.

Password the authentication password for register of this line must be entered here corresponding to the password set for the same device ID on MX.

Note: The following features are valid only in SIP protocol. When the gateways use MGCP protocol, the control of all call services is provided by the proxy server without the need of setting.



Page 34 of 48

Inbound handle


The gateways provide two scenarios for handling incoming calls of

FXO port:



“Second stage dialing”: When a telephone call comes to the FXO port, the gateways will provide the second dial tone and route the call according to the extension number pressed in. Note: dialing tone or voice prompt file can be changed by user.



“Binding”: When a telephone call comes to the FXO port, the gateways will route the call to a FXS port according to the DID number bound with the port. Note: Setting a number to be bound is required or this setting is invalid.

Polarity reversed signal detection

If a PSTN line supports reverse polarity, make a selection here. Or this setting is invalid. By default, this is not selected.

Caller ID detection Select if the detection function of caller ID for this FXO port is enabled. By default, this is selected.

Outgoing call barring

Select if this FXO port bars outgoing call service to PSTN. By default, this is not selected.

Echo cancellation Select if echo cancellation is enabled for this FXO line.By default, this is selected.

Connect signal delay

After making an outgoing call from a FXO port, the gateway will send a 200 OK message to the platform with delay if this parameter is selected. If unselected, the system sends a 200 OK message to the platform after off hook on the FXO port. Used with the configuration item of “Answer delay” on the “Advanced >

Trunk” interface.

10.3Advanced FXO settings

Suggested settings are

 Caller ID detection mode: After ringing A

 Outplusing Delay: 600

 The rest as defaults

Title

Gain to IP

Gain to PSTN

Impedance

Explanation

Set the voice volume gain towards IP side, the default is 0. Taking decibel as the unit, setting range is -3 ~ +9 decibels. -3 means declining of 3 decibels; +3 denote the amplification of 3 decibels.

Set the voice volume gain towards PSTN side, the default is -3.

Taking decibel as the unit, setting range is -6 ~ +9 decibels.

Set the parameter of FXO line impedance, with the default of 600 ohm. The optional settings as below:



Complex



600 （ ohm ）



900 （ ohm ）

Outplusing delay The time interval between FXO going off-hook and starting outpulsing the first digit to PSTN. The default is 400 in milliseconds.

Ring relay

Busy line handle

Whether to relay the ring of inbound call to the FXS port when applying to DID. The default is “FXS ring independently”.

Either a voice prompt or hanging up can be applied to FXO port



Page 36 of 48

Technical Publications when an incoming call goes to the FXS port which is in busy. This applicable only to DID feature.

PSTN failover

Caller ID detection modes.

Inbound first digit timeout

Answer delay

Off-hook for rejection

On-hook protection time

Whether to route a call to PSTN through FXO port when the IP network faults or no response to the call request. Default selected.

Before ringing A

Before ringing B

After ringing A

After ringing B

Set the timeout of calling DTMF on FXO port for inbound calls, ranging from 10-60 seconds, with default of 24 seconds.

Set the delay time of outbound connection ranging from 10-60 seconds, with default of 12 seconds. Working with “Line >Trunk” interface and “Connect signal delay” configuration.

Used for binding a FXO port with a FXS port. For inound calls to a

FXO port, if the FXS port which binging with the FXO port is in the state of busy line, the gateway will hang up after hook off according to the time set by the parameter, so as to refuse the upcoming call.

The duration of off hook is 500~5000 milliseconds, with default of

600 milliseconds.

Protection period following hang up of FXO port. During this period, gateway ignores any voltage variation of line. Value range is

100~5000 milliseconds, the default is 400 in milliseconds.

Polarity detection. Choose whether to activate the detection of reverse polarity signal of FXO port inlet. Note the detection will work only when the trunk supports polarity reversal.

Busy Detection

Repeat Gateways will regard the busy tone signal with the repeat times specified here as hang-up signal. Default is 2, effective range is 2 ~

5.

On-time

Off-time

Set duration of busy tone signal, the default is 350 in milliseconds.

Set the interval time of busy tone, the default is 350 in milliseconds.

11 Routing

The routing table in the MG8 is used to rout traffic between the MX, MG8 and the PSTN.

11.1Digit Map

Recommended patterns, (where extensions on MX are 5000 to 5999)

This will allow calling Voice Mail, Park Server, Page Server, Blind Transfer Code, dial internal extensions, and external calls.

 *77xx

 *4xx

 *38

 *86

 #xx

 5xxx*

 x.T

 x.#

 #xx

 ##

 *1



Page 38 of 48

11.2Routing Table


Recommended settings: (where 192.168.1.1 is the IP Address of the MX)

 FXS *38 ROUTE IP 127.0.0.1:5060

 IP 192.168.1.1:5060 ROUTE

 IP xxxxxx. ROUTE

FXS

FXO 1-4/R

 FXO x. ROUTE IP 192.168.1.1:5060

The above settings will allow

1.

Blind transfer by doing a hook flash on the FXS and dialing *38 , wait for the tone and then dial the transfer number

2.

Calls from the MX to the FXS ports on the MG8

3.

Calls from the MX to the MG8 that are 6 digits and longer are to be routed to the PSTN (FXO) starting from port 1 to port 4 in a Round Robin manner.

4.

Calls from the FXO ports to be sent to the MX

Calls from the FXS to the MX are handled by the registration/proxy process.

Number


Name

Routing Table Format

Description

Source There are three types of source: IP, FXS and FXO.

Among them, IP source can be any IP address and is denoted by

“IP”; “IP [xxx.xxx.xxx.xxx]” is used to denote specific IP address; “IP

[xxx.xxx.xxx.xxx: port]” is used to denote specific IP address with port number.

FXS and FXO ports can be any port, represented with “FXS” or “FXO”; special lines can be represented with FXS or FXO + port number, eg.

FXS1, FXO2 or FXS [1-2], etc.

It should be a calling number with the form of CPN + number or a called number with the form of number. The number may be denoted with digit 0-9,"*",".","#"," x ", etc., and uses the same regular expression as that of dialing rules. Here are some of the form of number:



Designate a specific number: eg.114

， 61202700;



Designate a number matching a prefix: such as 61xxxxxx. Note: the matching effect of 61xxxxxx is different from that of 61x or 61.



Specify a number scope. For example, 268[0-1 ， 3-9] specifies any

4-digit number starting with 268 and followed by a digit between 0-

1or 3-9;

Note: Number matching follows the principle of “minimum matching ”. For example: x matches any number with at least one digit; xx matches any number with with at least two-digit; 12x matches any number with at least 3-digit starting with 12.

Processing Mode

KEEP

Number Transformations

Description and Example

Keep number. The positive number behind KEEP means to keep several digits in front of the number; the negative number means to keep several digits at the end of the number.

Example: FXS 02161202700 KEEP -8

Keep the last 8 digits of the called number 02161202700 for calls from

FXS. The transformed called number is 61202700.

REMOVE Remove number. The positive number behind REMOVE means to remove several digits in the front of the number; the negative number means to remove several digits at the end of the number.

For example: FXS 021 REMOVE 3

Remove 021 of the called number beginning with 021 for calls from

FXS.



Page 40 of 48

Processing Mode

ADD

REPLACE

REPLACE



Add prefix or suffix to number. The positive number behind ADD is the prefix; the negative number is suffix.

Example 1:

FXS1 CPNX ADD 021

FXS2 CPNX ADD 010

Add 021 in front of calling numbers for calls from FXS port 1; add 010 in front of calling numbers for calls from FXS port 2.

Example 2:

FXS CPN6120 ADD -8888

Add 8888 at the end of the calling number starting with 6120 for calls from FXS port.

Number replacement. The replaced number is behind REPLACE.

Example: FXS CPN88 REPLACE 2682000

Replace the calling number beginning with 88 for calls from FXS port to 2682000.

Other use of REPLACE is to replace the specific number based on other number associated with the call. For example, replaceing the calling number according to the called number.

Examples:

FXS 12345 REPLACE CPN-1/8621

FXS CPN13 REPLACE CDPN0/0

For calls from FXS ports with called party number of 1234, removing one digit at the rear of the calling number and add 8621; for call s from FXS ports with calling party number starting with 13, add 0 in front of the called number.



Page 41 of 48


Processing Mode Description and Example

END or ROUTE End of number transformation. From top to bottom, number transformation will be stopped when END or ROUTE is encountered; the gateways will route the call to the default routing after meeting

EDN, or route the call to the designed routing after meeting ROUTE.

Example 1:

FXS 12345 ADD -8001

FXS 12345 REMOVE 4

FXS 12345 END

Add suffix 8001 to the called number starting with 12345 for calls from FXS ports, then remove four digits in front of the number to end number transformation.

Example 2:

IP[222.34.55.1] CPNX. REPLACE 2680000

IP[222.34.55.1] CPNX. ROUTE FXS 2

For calls from IP address 222.34.55.1, calling party number is replaced by 2680000, and then the call is routed to FXS port 2 with the new calling party number.

CODEC

RELAY

Designate the use of codec, such as PCMU/20/16, where PCMU denotes G.711, /20 denotes RTP package interval of 20 milliseconds, and /16 denotes echo cancellation with 16 milliseconds window.

PCMU/20/0 should be used if echo cancellation is not required to activate.

Example:

IP 6120 CODEC PCMU/20/16

PCMU/20/16 codec will be applied to calls from IP with called party number starting with 6120.

Insert prefix of called party number when calling out. The inserted prefix number follows behind REPLAY.

Example:

IP 010 RELAY 17909

For calls from IP with called party number starting with 010, digit stream 17909 will be pulsed out before the original called party number being sending out.

Routing Destination

Destination

ROUTE NONE


Calling barring.

Example:

IP CPN[1,3-5] ROUTE NONE

Bar all calls from IP, of which the calling numbers start with 1, 3, 4, 5.



Page 42 of 48

Select FXS port in a sequential way.

Example 2:

IP 800[0-3] ROUTE FXS 1

Point this call to FXS port 1.

Example 3:

IP 800[0-3] ROUTE FXS 1,2,3,4/g

For terminating the call from IP, ring FXS port 1, 2, 3, 4 simultaneously.

Route a call to FXO port.

Example:

IP x ROUTE FXO 1,2,3,4/r

Select the outgoing call FXO port in a round robin way.

Route a call to the IP platform.

Example:

FXS 021 ROUTE IP 228.167.22.34:5060

228.167.22.34:5060 is the IP address of the platform.

14 Troubleshooting

This section covers basic troubleshooting areas of the MG.



Page 47 of 48


14.1Calls do not complete correctly

Extend the “ Out Pulsing Delay” from 400 ms to 600 ms. This will extend the time from going off hook on the FXO before sending out the first DTMF tone.

This can be done on the Advanced Tab | Trunk page.

14.2Blank SIP messages are being sent to the MX from the MG

To stop the blank SIP messages which are used as a “Keep Alive” message to the MX, disable NAT Transversal, on the Advanced Tab | System page.

14.3MWI Lights are not set correctly

Change the MWI Subscription time from once every 24 hours (86400) to once an hour (3600 seconds). This can be done under the Advanced Tab | SIP page.

14.4DNS information is incorrect after updating a DNS server

DNS is cached on the MG and is only updated on a reboot. This can be modified by Zultys Technical Support.

14.5Local 3 way conferencing on the MG does not work

Local conferencing is disabled by default and can be enabled by Zultys

Technical Support.
