I am trying to implement IMS UPDATE method in SIP Communicator. I have add some IMS compliant header in SIP Communicator and now two instance of SIP Communicator is working till sending PRACK message. But I don't think it is working properly as I have leaved some header in the SIP Communicator invite message.
Because I don't think without Preferred Identity header the message routing will work perfectly.
Now I am trying to add Preferred Identity and P-Access-Network Info Header in SIP Communicator. Can anybody tell me how I can add this header with my invite request message? I have check the implementation in IMS Communicator, but it is bit tricky if I want to import the required functionality from IMS Communicator.
Is there any way that I can add all IMS compliant header in SIP Communicator by using new JAIN API?
I am sending the network trace my attachment. Feedback will be highly appreciable.
