Re: How to send a sip messages using domain name

What exactly are you trying to do?
I thought for this you will need a SIP registrar or a proxy server;
the user sends a REGISTER message to the SIP server. Then your user 
sends an INVITE to the SIP server for the user you want.
Depending on how the server works, it will either reply with a REDIRECT 
message, which will let you know which host the user is bound to (eg 
[email protected] can be contacted at [email protected]). Or if it works 
as a proxy server, it will contact the destination host on your behalf.
