Application Notes for Configuring QuesCom 400 IP/GSM
Gateway with Avaya Communication Manager using H.323
Trunks – Issue 1.0
Abstract
These Application Notes describe the configuration steps required for the QuesCom IP/GSM
400 to successfully interoperate with Avaya Communication Manager using H.323 trunks.
The QuesCom 400 IP/GSM is an IP-GSM-gateway, supporting outgoing and incoming GSM
calls. All GSM calls made from Avaya Communications Manager will be routed to the
QuesCom 400 IP/GSM gateway to the GSM network. The QuesCom 400 IP/GSM can also
receive calls from the GSM network and route the calls to Avaya Communications Manager.
The QuesCom 400 IP/GSM can provide a backup route for the PSTN and also be backed up
by the PSTN.
Information in these Application Notes has been obtained through compliance testing and
additional technical discussions. Testing was conducted via the DeveloperConnection
Program at the Avaya Solution and Interoperability Test Lab.

1. Introduction
These Application Notes describe a compliance-tested configuration consisting of a QuesCom
400 IP/GSM gateway networked with Avaya Communication Manager 3.1 using H.323 trunks.
The QuesCom 400 IP/GSM is an IP-GSM-gateway, supporting outgoing and incoming GSM
calls. All calls made from Avaya Communications Manager destined for the GSM network will
be routed to the QuesCom 400 IP/GSM gateway. The QuesCom 400 IP/GSM can also receive
calls from the GSM network and route the calls to Avaya Communications Manager. The
QuesCom 400 IP/GSM can provide a backup route for the PSTN and also be backed up by the
PSTN. This can be configured in Avaya Communication Manager using Automatic Route
Selection (ARS). These Application Notes focus on a configuration where an H.323 IP trunk
connects Avaya Communication Manager and the QuesCom 400 IP/GSM.
In Figure 1, Avaya Communication Manager runs on the Avaya S8500 Media Server. The
solution described herein is also extensible to other Avaya Media Servers and Media Gateways.
The Avaya G650 Media Gateway is connected to the PSTN via an E1 ISDN-PRI line and to the
QuesCom 400 IP/GSM via an H.323 IP trunk. The QuesCom in turn connects to the GSM
network via Subscriber Identity Module (SIM) cards that reside on GSM boards inserted in the
QuesCom 400 IP/GSM.

5. Enter the change trunk-group n command, where “n” is the trunk group number configured in
Step 2. On Page 3 of the trunk-group form, configure the following:
• “IP” for Port. The number of ports configured should be coordinated with the number of
SIM cards available in the QuesCom 400 gateway.
• The number of the signaling group configured in Step 3 for Sig Grp.

3.4. ARS Tables and Route Patterns
In the sample configuration described in these Application Notes, when placing outbound calls to
the public network, stations on Avaya Communication Manager must first dial the ARS Feature
Access Code (FAC) before dialing an external number. The single digit “9” was used as the
ARS FAC in the compliance-tested configuration (configuration step not shown).
Step Description
1. Enter the change ars analysis 0command. Configure Dialed String entries according to
customer requirements. In the example below, the entries match dialed numbers as follows:
• The “078” Dialed String matches 11-digit dialed numbers that begin with 078, and
routes calls to Route Pattern 78. For example, a dialed number of 07891 900 128 would
be matched by this entry.

Step Description
2. Enter the change route-pattern n command, where “n” is the route pattern that processes dialed
numbers configured in Step 1. Add two routing preference entries as follows:
1) First Routing Preference – H.323 IP trunk to QuesCom 400
• Grp No – enter the trunk group number routed to the QuesCom 400 gateway (see Section
3.3, Step 2)
• FRL - assign a Facility Restriction Level to this routing preference.
• LAR - set Look Ahead Routing to “next” to rehunt within the next routing preference if
calls are rejected. LAR allows Avaya Communication Manager to re-attempt the call on
another channel if the call is rejected with certain cause values.
2) Second Routing Preference – PSTN E1 ISDN-PRI
• Grp No – enter the trunk group that contains trunk members from the PSTN E1 ISDN-PRI
(see Section 3.2 Step 2).
• FRL - assign a Facility Restriction Level to this routing preference.

3.5. Avaya Extension to Cellular(EC500) Configuration
Avaya Extension to Cellular allows a cell phone to be treated as if it were an extension defined in
Avaya Communication Manager. This is accomplished by mapping the user’s main office phone
to the cellular telephone number. All other types of calls, such as direct calls to and from the
published cell phone number, are unaffected by Extension to Cellular.
Step Description
1. Verify that the Avaya Communication Manager license has permissions for EC500 extensions.
Enter the command display system-parameters customer-options. On the OPTIONAL
FEATURES screen, verify that the Maximum Off-PBX Telephones - EC500 is sufficient.
