Incident Description:

Equipment: Mitel 3300 MXe 3 with software version:

Deployment: Residential Alarm Monitoring Company. Brand new deployment. Converged (voice and data) network. Several Mitel 5340 IP sets which are ACD enabled and have Hot Desk ACD agents logging into them. These sets have LIM modules installed. The analog line connecting into the LIM comes from a v.92 modem interfaced with a client PC that is used to auto dial outbound contacts during alarm condition home residential alarm monitoring calls.

Situation/Issue: Randomly while using the LIM to dial outbound calls the Mitel phone seems to “freeze up”. The analog call is dropped yet the 5340 IP set seems to hang on the line. The cancel key can be pressed to hang up the analog call. At this point if either the analog or prime DN line is then selected no dial tone is presented through the receiver. Other functions of the phone appear to work correctly. The Superkey can be pressed, the menus can be cycled through, ACD agents can log in and out. However further calls will not be delivered to the set and no dial tone will be heard when selecting a line. In some cases an error message is presented on the LCD display of the 5340 IP set: “Assert @ 4474 SL_AudioTask Id: 94df7ef0” or “Assert @ 4474 SL_AudioTask Id: 949e5270” or “Assert @ 2005 SL_AudioTask Id: 94df7ef0”. In all cases the phone must be power cycled before it becomes operational to take calls again. There is no predictable pattern to the outages however it does seem like phones fail in groups of 2 or 3.

Does anyone have any ideas to point me in the right direction at all?
 
Equipment:
Release Level: 7.0 PR1
Active Software Load: 13.0.0.83
Inactive Software Load: 10.0.4.14
Platform: MXe-III, 512MB of RAM
 
Cause discovered: calls were disconnecting and locking up the set when the Group Alert (with ring) key became activated.
 
Question - Are you a fan of the movie "Oh Brother Where Art Thou"?

If you are, the reason for my asking should be obvious.
