<div>Hello together,</div>
<div>currently i'm trying to configure a freeswitch to setup a sip-trunk for direct-routing with Microsoft Teams.<br/>
So far i had no luck to get a registed sip-trunk.<br/>
Does anyone has so far a working config for a registed sip-trunk with MS-Teams ?</div>
<div> </div>
<div>On two websited with a Sample-Configuration with a diffrent-system:<br/>
https://skalatan.de/en/blog/kamailio-sbc-teams<br/>
https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/<br/>
they talk about two header-settings that are not correct in my config or are missing</div>
<div> </div>
<div>1. Microsoft needs a contact header in form of:<br/>
--<br/>
Contact: <sip:FQDN-SERVER:5061;transport=tls><br/>
--<br/>
my contact-header looks like:<br/>
Contact: <sip:FQDN-SERVER@IP-SERVER:5061;tport=tcp;transport=tls;gw=ms-teams><br/>
--<br/>
How do i get rid of "@IP-SERVER" and ";gw=ms-teams" from the contact-header in freeswitch ?</div>
<div><br/>
2. there is a "record-route-header" missing in the format:<br/>
--<br/>
"FQDN-SERVER:5061;transport=tls", "IP-SERVER:5060"<br/>
--<br/>
How do i set this record-route-header in freeswitch ?</div>

as fas as i could see everything including the exchange of the public-certificate works fine, but afterwards i get a timeout for that trunk.<br/>
