[SR-Users] how to use get my domain name in VIA header (INVITE) instead of IP address.

[Yuriy Nasida]

Guys, I really happy that you send INVITES to MS with record_route_preset
and MS does not ignore. But I really not sure how your INVITE looks.
Can you please send one here ? That can help a lot. Also please look at
INVITE we send (MS ignores this).
