Hi, I need to modify some data in a PRACK I send. Actually I used 100Rel API to manage Early SIP Message because it's simple. But with this API, I don't find any CallBacks call for sending PRACK like callback for the ACK of the INVITE Session API. So I can't manage PRACK unless I modify the API. I don't want do this, but I don't know how modify PRACK message. May be with Dialog API, but can I use in same time the Dialog API and the Invite Session API and 100Rel API ? Another solution is create my own API, but it's difficult when I see INVITE Session API. Thanks in advance for your response.
