[asterisk-users] asterisk18.6.0 with old chan_sip and microsoft teams
Hi, I had a different thread going about about no audio with asterisk - I thought it was due to two network cards - but I dont think so any more. The endpoint is microsoft teams - and I think that might be the issue. Does Asterisk 18.6.0 work with Microsoft teams ? my issue is no audio. I have done a tcpdump -i eth0 and I see the audio traffic going back on that network - so I presume I am good - What can I do so teams sees the audio ?

As far as I understand it, this hasn't been possible without placing an SBC such as Kamailio in the middle, but if it is possible, that would be interesting.> Does Asterisk 18.6.0 work with Microsoft teams ? my issue is no audio.I'm slighly impressed you appear to have the initial registration working.> I have done a tcpdump -i eth0 and I see the audio traffic going back on > that network - so I presume I am good - What can I do so teams sees the > audio ?What does something like sngrep or tshark/wireshark tell you is going on with the SDP negotiations?

That 2600 SBC then passes the call over to the Marion Audiocodes Mediant 1000. " So teams -> 2600 SBC -> Mediant 1000 -> Asterisk 18.6.0 - Call does come in - looks normal but they report no audio heard back at source.
