<font face="Calibri Light">Hello<br>
<br>
i manage to fix this. I did not do t_relay() also seq Invites,
after this everything works ok.<br>
<br>
Just on question, regarding transfers, i see that MS Teams send
REFER in which trafter is defined. How do you deal with this? You
do not allow REFER from MS teams and hope that MS teams will send
new INVITE?<br>
<br>
<br>
thank you<br>

<div>First, do you need to use "<a href="http://mtsbc.test.com:5060" target="_blank">mtsbc.test.com:5060</a>"
in the first record_route_preset() param? Can you use the IP
address of your proxy instead? FQDNs are legal of course, but
outside of MS Teams' implementation, they're rarely required.
It's just another thing to go wrong. Especially while
testing.</div>

I have an issue and I am unable to find out what is wrong.
Incoming calls are working but when doing outbound call
after 200OK, which is send to Teams I get back ACK and
after that Teams do again initial. I guess this is not ok.<br>

I am doing this for outband calls:<br>
