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.

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.
