Hi Srinivas,
UPDATE is a method which is used to modify the media parameters even in the early dialog state.
So there is no fault in sending the UPDATE before the dialog moves to established state(i.e 200 OK and ACK completed).
Regards
Srinivas

I am not seeing ACK to 200 OK ( of INVITE ) in your traces before UPADTE. It means dialog is not fully establish. So, your device is sending UPDATE before dialog fully establish. UPDATE is to update the params with in the dialog. Please check for why device is sending UPDATE before ACK for 200 OK is received. That's why it says, not DIALOG exist.

<----------- UPDATE coming before ACK below Tx----------
---------ACK is missing --------------->

Hi Gents,
Please describe how to handle SIP UPDATE Message as Device A is giving SIP 481 Call Leg/Transaction doesn't exist when Device B replied with SIP UPDATE request. After that it is SIP 487 request Terminated by Device A.
Please advice how to trouble shoot this.
