Introduction; Interoperability Testing - Avaya 1000E Application Notes

1. Introduction

There are installation instances of Avaya Communication Server 1000E which are not SIP or IP
capable, or where the software release may not have been SIP interoperability tested, but the
customer wishes to deploy Avaya Meeting Exchange Enterprise Edition. In this case an effective
solution is to front end the Avaya Communication Server 1000E with an E1-PSTN to SIP
gateway, which signals via SIP trunks to Avaya Aura ® Session Manager R6.2, which in turn
has a SIP trunk to Avaya ®Meeting Exchange Enterprise Edition. This configuration supports
basic and advanced conference features.

2. Interoperability Testing

The solution in this document uses the following configuration:
Avaya® Communication Server 1000E (CS1K) is configured with an E1/PSTN link to Dialogic
IMG 1010 Media Gateway (IMG_1010). In turn, the Dialogic IMG 1010 Media Gateway is
configured with a SIP trunk to Avaya Aura ® Session Manager R6.2. Session Manager is also
configured with a SIP trunk to Avaya® Meeting Exchange Enterprise Edition R6.2.
The incoming call from the Avaya ® Communication Server 1000E is presented as E1 to the
Dialogic IMG 1010 Media Gateway. The E1 signal is converted to SIP by the IMG_1010 and
signaled to the Avaya Aura® Session Manager R6.2 using TCP, with DTMF being transmitted
within the RTP stream using RFC2833 compliant messages. Avaya Aura® Session Manager is
configured with SIP Entities for Dialogic IMG 1010 Media Gateway and Avaya ® Meeting
Exchange. Entity links have also been created between Session Manager and Dialogic IMG 1010
Media Gateway and Session Manager and Meeting Exchange dictating the protocol and ports to
be used, i.e. TCP/5060.Additionally, a routing plan and dial pattern has been created on Session
Manager to route calls to Meeting Exchange when the relevant conference number has been
dialed.
Additionally a SIP trunk and relevant digit patterns were also added to Avaya Aura ®
Communication Manager R6.2 for the purposes of managing the Avaya H.323 endpoint that
comprised part of the test phones.However testing did not focus on this side of the Avaya PBX
environment.
The Avaya Meeting Exchange Enterprise Edition R 6.2 is a new release of software, and can
now be managed via the Avaya Aura® System Manager as a Managed Element. The initial
configuration of Meeting Exchange as a Managed Element is not covered in this document. For
more details, see Section 11 Reference [6].
Note: A third party PBX was connected to the solution to represent an ―external PSTN‖ caller
dialing to the Meeting Exchange conference service via Avaya Communication Server 1000E.
The configuration of the E1 trunk between Avaya Communication Server and the third party
PBX is not covered in this document.
