Re: [SR-Users] Kamailio drop calls with Teams

You have to use record_route_preset when the message is sent from Kamailio to Teams if (from_uri =~ ".*microsoft.com") { record_route(); } else { record_route_preset("SBC-DNS-DOMAIN:5061;transport=tls", "SBC-IP-ADDR:5060"); } On Thu, 3 Sep 2020 at 13:13, sip user &lt;sipuser404(a)gmail.com&gt; wrote: > Thanks Pepelux.. > > Yes, I follow that post to configure it.
