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.

Cheers,
Daniel

While I don’t know if it will or won’t cause the failure, you shouldn’t have a port number in something you’re intending to use as a SRV record.

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.


Regards,

Are you using a hostname that should resolve as srv , for example, sip.domain.com, or are you using the underscore, scheme, underscore transport protocol, hostname type like _sip._udp.domain.com ?

Hello guys,

 

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

 

Thanks,

 

David Villasmil
