RE: [reSIProcate] How to differentiate "invite" or "holdoff"?
If both invites are initiated by your app then the CSeq in the message
should be different. Also if the SDP is changing (for hold/unhold) the SDP
version number should be incremented. The only other way (I can think of)
would be to maintain state in your application.
Perhaps we should consider exposing the InviteSession state to applications.

Subject: [reSIProcate] How to differentiate "invite" or "holdoff"?
Hi all
I can not differentiate two situations as follows.
(Terminal A and Terminal B as example for my description)
Situation 1:
When initially establish Call,
A send INVITE with Sdp to B,
then B answer it and return 200ok with Sdp to A,
and then A recevive 200ok and call virtual function
virtual void
InviteSessionHandler::onAnswer(InviteSessionHandle is, const SipMessage&
msg,
const SdpContents& sdp)
Situation 2:
When HoldOff,
A send same INVITE with same Sdp to B,
then B answer it and return 200ok with Sdp to A,
and then A recevive 200ok and call virtual function
virtual void
InviteSessionHandler::onAnswer(InviteSessionHandle is, const SipMessage&
msg,
const SdpContents& sdp)
I want to know in Terminal A,
How to differentiate this two situations in function onAnswer()?
I think the two "msg" and the two "sdp" are all same,
maybe there are some difference in "is".
Thank you very much.
