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

Hi Pepelux, I have this one: remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) { if($src_ip != "IP ASTERISK"){ record_route(); xlog("L_INFO", "***********ROUTE PSTN***********"); $rU="1005"; } else { xlog("L_INFO","LLamada desde $si con puerto $sp"); record_route_preset("FQNDDNS:5061;transport=tls", "FQNDIP:5060"); add_rr_param(";r2=on"); route(DISPATCH); route(RELAY); } } When the call is from Teams (src_ip != "IP ASTERISK"), incoming calls, I send the call to 1005 extension. Is here where I have to make the change? Or where? Thanks El jue., 3 sept. 2020 a las 12:14, Pepelux (&lt;pepeluxx(a)gmail.com&gt;) escribió: > Hi > > Kamailio doesn't receive any ACK from Teams.
