Thanks Brett, is there any specific standard which indicates that INVITE
dialog will be using same connection of REGISTER ?
RFC 5626 is the only one
Thanks,

RFC 5626 will likely be helpful.

Subject: [Sip-implementors] TCP/NAT handling in SIP
Hi,
If the UA is behind NAT registers on TCP and after that it initiates a
call
on same connection (may be another connection ?) after some time
connection
break now as soon as UA detect that the connection is closed it
initiates a
new REGISTER using new connection (It is not changing contact as it is
listening on default port).
1. Should UA send a re-invite/update for modifying the connection
status
within a call ?
2. If No, then whether it is recommended in any of standard that we
should
use the same connection for sending any request ?
3. Is there any RFC which mention the connection handling between
REGISTER
request and INVITE request ?
Any inputs are appreciated.
