Skype for Business hybrid - Issues between on-premise and Teams only users
KennethML In the meantime, I tried to continue the troubleshooting, and I found out the following:
It seems that the Skype for Business client disconnects the call because we don't get any answer for our OK mesage.
Let me show you these screenshots:
Do you have any ideas about why don't we get ACK for the 200 OK? I checked the network with no luck and I don't have any more ideas.
It could still indicate a problem with setting up the media path as the ACK should be sent when media path is established (late media).
Ye maybe the media path changed without documentation?!
I have already tried with "ANY-Port/Protocol" for incoming and outgoing for the EDGE-Part - same issue.Also i dont think its media (only) because we cannot see the peresence of the Teams users from onprem. But its working if i query an onprem user from Teams.
- Same issue here, presence is one-way, SfB on-premise users see Teams only users as offline users.
The strange thing with the call issue is that the audio connection will be built up without any issue, I can hear the remote party, he/she can hear me but the call will be dropped after 30 sec.I made another interesting observation - i can still see the presence from other tenants from onpremise - tested with three external teams domains.
But not from our tenant.
