Solved Ringback Tone for outgoing calls

[Mercuris]

Hi All,

As many of you, I set up the 3CX - Teams integration with success.
Incoming call works
Outgoind call works too, excepted the ringing tone.
I did a trace, but the leg between Teams and 3CX is encrypted, and I can't see if the 180 ringing
What i'm totally sure is "when I call the same number from my 3CX desktop app, or deskphone or Dect M70, I heart the ringing tone well?

do you have the same experience?

BR

Hi!

Check something please, start a packet capture from the 3CX Management Console and make an outgoing call from Teams where you don't hear the "ringing" sound.
Stop the capture, open it with Wireshark, and check if the provider is sending you a "180 Ringing" w/o SDP, "180 Ringing" w/ SDP or "183 Ringing" w/ SDP.

What is being sent?

Could you please send me this capture in a PM (upload it to a file sharing service of your choice)?

Just an update for the rest of the forum, the thing that resolved the issue was kind of odd, logging out of all devices (Teams Desktop App, Teams WebClient, Teams mobile App, etc...), then logging back in seemed to do the trick.
