Before :
 
 New request - M=INVITE RURI=sip:7722 at domain.org;transport=tcp F=sip:user2 at domain.org T=sip:7722 at domain.org IP=192.168.80.222 ID=771b514742765432N2I0ZTAwZTMzZmE1ZGUwYjc4MWNhYTM3NTA3N2RjNWY.

After :

 Rewrite!!! - M=INVITE RURI=sip:7722 at domain.com;transport=tcp F=sip:user2 at domain.org T=sip:7722 at domain.org IP=192.168.80.222 ID=771b514742765432N2I0ZTAwZTMzZmE1ZGUwYjc4MWNhYTM3NTA3N2RjNWY.
