Test Results - Avaya GXV3240 Application Notes

The serviceability testing focused on verifying the ability of the Grandstream phones to handle
various outages such as network disconnects and server/phone reboots.
The wireless functionality of the Grandstream phones was not tested.

2.2. Test Results

The Grandstream Multimedia IP Phones successfully passed compliance testing with the
following observations:
 G.726-32K: G.726-32K codec negotiation failed during compliance testing; however,
Grandstream has delivered a fix for this issue in their system firmware version 1.0.3.25.
 Conference URI / display updates: When the conference is established, the endpoints
involved in the conference receive a SIP UPDATE message with a Contact header
containing the "isfocus" feature tag. This feature tag indicates that the URI in the
Contact header field is a conference URI. Avaya phones update their display to show the
conference URI display information (e.g. Conference 2) which indicates the number of
other parties in the conference. The Grandstream phones did not update their display to
show the conference URI display information; however, Grandstream has delivered a fix
for this issue in their system firmware version 1.0.3.25.
 Long Hold Recall: The Grandstream phones do not audibly or visually alert the user of
a held call when the Avaya Aura® Communication Manager long hold recall timer
expires.
 481 Call Leg/Transaction Does Not Exist: Multiple "481 Call Leg/Transaction Does
Not Exist" SIP messages are generated for transfer/conference scenarios. This is
essentially a race condition. For example, after the REFER for a transfer is sent, both
parties send a BYE for the call leg going away. When each party receives the BYE, it
responds with a 481 Call Leg/Transaction Does Not Exist (since each party has already
sent its own BYE for that call leg).
