DNS SRV not honored in 3.2.0

[Mikael B]

Binary package hint: ekiga

Ekiga attempts to connect to port 5060 of the FQDL provided although valid NAPTR and SRV records point to port 5080. The same FQDL has worked correclty on earlier Ekiga versions as well as the 3.2.0 previously found in a PPA. I have the same setup working on a range of clients. Ekiga is the only client having trouble with it.

Hostname is fs.voip.consoll.no which based on DNS views in BIND points to port 5080. You will get 5060 from the internet.

The problem must be reported upstream if that's where the problem lies. The problem might even be OPAL. I haven't been able to compile Ekiga from source so I'm unable to verify this.

What's interesting is that the REGISTER goes to 5060 while subsequent requests seem to go to 5080. REGISTERs should also go to 5080. On my FreeWITCH server 5080 is a profile only used for RFC1918 addresses (our network) and 5060 is facing the internet. I am sitting on an RFC1918 address on the LAN.

Attached is a log showing that REGISTER goes to 5060 while SUBSCRIBE goes to 5080.
