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.

Hi Jayesh,
This is the exact purpose of UPDATE - to update the dialog remote target before the dialog is established.
But of course, properly implementing and following it is up to the endpoints.

Hello, In a user-user based calling on mobile apps, when the call is connected
and the user moves from a Wifi to Mobile data (network change); the device sends a Re-Invite with new contact information and subsequent messages go to appropriate changed contact address.
But when the dialog is in say ringing state; and the caller moves from
one network to another; what would be an appropriate SIP method to trigger the contact update. My problem is generating a Re-INVITE or an UPDATE before the call is connected is very difficult.
What I tried is sending an in-dialog INFO message with new contact
address; which gets relayed to the called party and the response for INFO is also properly received on the new contact address. But the subsequent response of the INVITE like a 486 or 200 goes to the original contact only.
What would be the best way to update the contact address of a client if
I'm maintaining all the dialogs in kamailio.
Thanks,
