Application Notes for configuring the Usnetserve aGATE by Teles GSM Cellular Gateway with an Avaya telephony infrastructure using Avaya Aura™ Communication Manager to provide a GSM Wireless Backup for Landlines through an E1 ISDN-PRI Line – Issue 1.0

Abstract
These Application Notes describe a compliance-tested configuration comprised of AvayaAura™ Communication Manager and the Usnetserve aGATE by Teles GSM Cellular Gateway. The aGATE GSM Cellular Gateway is a GSM gateway that can augment landline connectivity with wireless connectivity to the GSM network. In case of landline connectivity failure, the aGATE provides a backup solution to maintain voice communications. During compliance testing, outbound calls from Avaya Aura™ CommunicationManager were successfully routed over an E1 ISDN-PRI line to the aGATE and in turn to the GSM network. Similarly, inbound calls from the GSM network to the aGATE were successfully forwarded to Aura™ Communication Manager over the E1 ISDN-PRI line. Information in these Application Notes has been obtained through DevConnect compliance testing and additional technical discussions. Testing wasconducted via the DevConnect Program at the Avaya Solution and Interoperability Test Lab.

1. Introduction
These Application Notes describe a compliance-tested configuration comprised of Avaya Aura™ Communication Manager and the Usnetserve aGATEby Teles GSM Cellular Gateway. The aGATE GSM Cellular Gateway is a GSM gateway that can augment landline connectivity with wireless connectivity to the GSM network. In case of landline connectivity failure, the aGATE provides a backup solution to maintain voice communications. These Application Notes focus on a configuration where an E1/ ISDN-PRI line connects Communication Manager and the aGATEGSM Cellular Gateway.

1.1. Interoperability Compliance Testing
The interoperability compliance testing focused on verifying the routing of outbound/inbound calls to/from the Usnetserve aGATE by Teles GSM Cellular Gateway. The high-level objectives of the solution described in these Application Notes are as follows: 1. When the landline is out of service, Communication Manager will route alloutbound calls to the aGATE. 2. When the landline is out of service, inbound calls from the GSM CELL network route through aGATE Gateway and are routed to the Communication Manager. 3. If the landline is operational, Communication Manager will re-route calls rejected by the aGATE to the landline. The Enterprise callers can enter an “aGATE Gateway Dial Prefix” to use the aGATE Gateway to make calls.For example, Enterprise callers place outbound calls via the aGATE and GSM network to reach GSM endpoints and save on GSM Cellular minutes and costs.

2. Reference Configuration
In case of landline connectivity failure, the aGATE provides a backup solution to maintain voice communications. When the landline is operational, outbound calls to the public network may be routed to eitherthe landline or the aGATE, but when the landline is out of service, outbound calls to the public network are routed to the aGATE only. The aGATE routes the outbound calls to the GSM network, but may also reject outbound calls under certain configurable conditions. The caller, however, may bypass such restrictions by dialing a pre-configured “aGATE Dial Prefix” before dialing the external phone...
