[reSIProcate] About the ACK

[Karlsson]

Thanks for your answer:
I mean:

1: UAC call UAS without SDP
2: UAS replied 200 with SDP
3: UAC will be fires the onConnected and send a ACK without SDP to UAS
4: UAC will be fires onOffer
5: use the provideAnswer to send a ACK with SDP

Then UAS will received two ACKs?


Another questions:
I want to send a INVITE without SDP body, I using:

SharedPtr<SipMessage> inviteMessage = mDum.makeInviteSession(NameAddr(callee),
profile, NULL);

The program crashed.

thanks
