Partner here.. just moved a client to O365/teams for voice as part of a office relocation and deployed (15) T56A phones. On latest FW & teams app, however my client is having the issue with the call queue calls going to hold & needing to be resumed, for every call, inevitably resulting in many dropped calls. They are also having drops when warm/cold transferring as well, although sporadic.
The deployment is about as vanilla & 'white paper' as you can get:
- Tenant is pure teams (no SfB)
- Teams voice switched from SfB legacy portal a couple of weeks ago
- No SBC/DR.. all users using calling plans
- 2 AA's and 2 CQ's, only 5-6 agents in queues
- T56a teams edition 'certified' phones from 'certified' partner, UC.com
- FW: 58.15.0.38
- Partner App: 1.15.0.19043022
- Portal: 5.0.4295.0
- Teams Version: 1449/1.0.94.2019043004
Calls to DID's are fine, calls thru AA's/CQ's are the issue. Calls are fine with teams app on PC.
I have:
- Logged case with yealink & escalated over a week ago, which was flat out ignored
- Logged case with MS earlier this week (14527392).. some back and forth, sent logs, sent video, sent logs again, sent other info requested, no sense of urgency or a solution
- Logged case with UC.com today.. no response back yet
On a test phone I have here, after rebooting several times, the phone will now let me pick up a call from a queue, after a very un-natural 4+ second delay establishing session/transferring call.. to myself? But, this is the first time I have ever seen it work at all, so I don't have warm & fuzzies.
In short, I currently have a 15 yr client who wants their phones to work, and is coming after me with pitchforks... need some help here please!!
