INVITE sip:bob@biloxi.com SIP/2.0

From it, I thought one could literally find domain names in SIP URIs.
Technically that's possible, but all it means is that the underlying network stack is doing the DNS/address resolution and not showing it to the application layer.

It's like opening a web browser and typing in "www.yealink.com" in the address bar. When you do that, your computer uses DNS to translate "yealink.com" into an IP address, but you as the user don't see that happen.

Same thing with SIP packets. The difference is that most SIP applications (i.e. the client running on the Yealink phones, or the PBX itself) don't expect end users to be watching the actual packets/requests flowing back and forth, so for coding efficiency purposes they do the translation directly and encode the IPs into the packets instead of the domains.

Probably more of an answer/explanation than you were looking for, but hey too much info is always better than too little ;o)
