Hi Folks,
 
UA1 --> P1 --> P2 --> UA2
 
1. UA2 gets INVITE message as follows;
 
 INVITE sip:1...@xyz.com
      Contact: sip:1...@abc.com
      Record-Route: <sip:proxy2.com;lr>
      Record-Route: <sip:proxy1.com;lr>

Question is "When UA2 generates any message within dialog say BYE,
Request-URI will be set to 'sip:1...@abc.com' or 'sip:proxy2.com'? This is a
case where proxy2 follows loose routing.
 
2. UA2 gets the INVITE message as follows; 
 
 INVITE sip:1...@xyz.com
      Contact: sip:1...@abc.com
      Record-Route: <sip:proxy2.com>
      Record-Route: <sip:proxy1.com;lr>
 
Question is "When UA2 generates any message within dialog say BYE,
Request-URI will be set to 'sip:1...@abc.com' or 'sip:proxy2.com'? This is a
case where proxy2 follows strict routing.
 
Will appriecate your comments.
 
Best Regards,
Vivek Batra
