Hello, indeed, as mentioned, the presence of a port in a SIP address makes it to skip SRV lookup. Anyhow, I am jumping in to see what is the Kamailio version used in this scenario? I don't recall exactly, but a while ago there was a related commit, at least it looked like when I did some backports today for next planned release in 5.6.x series.

Hey all, Joel, it’s failing saying the destination is unresolvable and Ben, I’m setting it like Listen=tls:1.2.3.4:5061 advertise mydomain.com:5061 My domain.com srv is like _sips._tcp.domain.com resolving to sip.domain.com (among others like udp, etc) I would expect Kamailio to resolve its own srv, or have an option NOT to attempt to resolve and just the set host in the record-route, but maybe that’s just not how it works. Yes, setting sip.domain.com:5061 works but the the record-route would have that (sip.domain.com) exact same host and the client might disconnect and reconnect to that dns instead of the actual SRV.

Hello guys, I'm trying to use an SRV as an advertised address but kamailio fails to start. Is this not possible?
