We have Poly VVX 411s and migrated from SfB to Teams in Jan. this year. All users are now Teams only with O365. Our IT staff have all migrated to headsets working with the Teams desktop client so we wouldn't have noticed this issue. We'd like to move all users that direction but will always have some users that can't live without a desk phone. As new phones are needed we've moved to CCX 400/500/600s but we can't replace 1600 VVX 411s at once.
About 2 weeks ago, some 411 users reported they could no longer add a 3rd user to an ongoing call. I've tested on a 411 and adding another caller shows "Connecting to Conference" followed by "The conference service is unresponsive. Try again later." Tapping Meet Now on the 411 has the same result. Is this expected behavior for a 3PIP phone or do we have something misconfigured with our Skype to Teams interop? I have to believe we would have had complaints back in January if none of the 411 users could add additional callers.
Looking at Interoperability of Teams and SfB, is this what is meant here?
- Escalating an ongoing peer-to-peer voice or video call to a multiple-party call involving both Teams and Skype for Business users isn't supported.
Our 411s are on FW 6.3.0.14929 and paired with the user's device using BToE 4.3. I've tested with the same results with the only available upgrade, v. 6.3.1.8427.
I cleared the logs, tapped Meet Now, and then captured the log (attached).
Thanks in advance.
