    32 second disconnect on SIP trunks for only one member of the Coverage Answer Group

    and, updated. Customer just received this from AT&T. Good to know. I just received notification from the vendor (Ribbon) on your open issue. Per the vendor, “The official word from engineering is that the call exceeds the limit on max number of Ringing messages with different To tags. The limit...

    32 second disconnect on SIP trunks for only one member of the Coverage Answer Group

    Update, such as it is. Yesterday: AT&T Tier 2 has acknowledged he wasn't seeing ACK. AT&T Tier 3 says "Ribbon is seeing the ACK being passed back to the server. So we need more logs to prove and or disprove" Assumption this is between AT&T servers and Edgemark on-site router, since Tier 2 has...

    32 second disconnect on SIP trunks for only one member of the Coverage Answer Group

    KYLE555. I thought a TEG only handled one call at a time? I have floated the idea of just building a Hunt Group. We've got Elite licenses. But if the issue is the header for 3288, not sure if experience would be any different. Will know more after call at 11:00

    32 second disconnect on SIP trunks for only one member of the Coverage Answer Group

    AvayaTier3. thanks! I had floated that yesterday and just checked with customer and my tech. They tried it this morning, but no joy. I did find that in playing around with it, they changed the member of Position 3 to the customer telecom guy, taking the original P3 out. and left position...

    32 second disconnect on SIP trunks for only one member of the Coverage Answer Group

    Sorry guys, but reaching out in desperation. I'm the AE (not a tech) with an unhappy customer. TL;DR version. one extension (only) in a CAG disconnects after 32 seconds of a SIP call. Other four work normally. Details. Environment is CM R6.1, Session Manager, System Manager, Portwell ASBC...

    5400 phone and conferencing

    Customer has IPO 412 R4. After four months of no complaints, they find that when initiating an add-on conference call from the speakerphone, the microphone stops working. If they pick up the handset, works fine. If they press speaker again, the mic goes mute. Doesn't matter if outbound...
