The test effort verified a basic level of interoperability between the Mediatrix 1100 and 4100 series, and Nortel’s Application Server 5200 (AS 5200) Release MCS09. This successful testing establishes the Mediatrix 1100 and 4100 series as a Nortel registered product for the releases tested. Testing included basic communication and basic call functionality between the devices. It is the service provider’s responsibility to perform appropriate system and network integration of the Mediatrix 1100 and 4100 series with the AS 5200 based on their network deployment requirements.

Nortel testing included:

AS Registration
Basic SIP Calls (call originations and terminations)
Basic SIP calls - Client behind a NAT/Firewall
SIP CPL - Call Forking
SIP DTMF - Transport Reliability
SIP Client Instant Messaging (IM) - receive instant    messages
Presence Update upon Login
SIP Client Refer Services
Refer Services - Client Under Test behind a NAT/Firewall
Enhanced Service - E911 Call to Emergency Services


Test Exclusions:

-Redundancy, carrier grade, traffic or robustness scenarios were not tested as these fall outside of basic interop testing
-Voice Quality was only checked through audible means between parties.
-Mediatrix does not support video initiation.
-Mediatrix does not support initiation of in call codec negotiation
-Nortel test lab does not have a second AS server for testing Basic Call origination (call is redirected by AS)
-AS server in the Nortel test lab is not configured for E911.

Anomalies not causing failure

The following 4 Nortel MMPC features are not supported by Mediatrix but Mediatrix is able to reject them gracefully with no negative impact to the existing calls. Therefore, related testcases are still considered PASS.
-Video --- Mediatrix rejects it gracefully with a m:video 0 in the SDP negotiations.
-Sharing --- Mediatrix rejects it gracefully with a 420 Bad Extension.
-Web push --- Mediatrix handles it gracefully with a 405 (Method Not Allowed).
-IM --- Mediatrix handles it gracefully with a 405 (Method Not Allowed)

   Test Conditions
-It was agreed between Nortel and Mediatrix that testing would be done in G711 (u or a) and a ptime of 20ms. Mediatrix provided traces in G711u, 20ms.
