[SR-Users] in-dialog contact update before dialog being confirmed

[Jayesh Nambiar]

Hello Alex,
I managed to send the UPDATE method from my endpoint but still the kamailio
is not updating the new contact. The UPDATE method is simply loose routed
from caller-callee when a network change is detected on the client. Though
the UPDATE is relayed and responded back correctly; the subsequent response
still goes to the initial contact address.
Also when the dialog is established; kamailio correctly updates the contact
on Re-Invite but it does not on an UPDATE method.

Anything particular to be done in this case. Thanks.

- Jayesh
