Re: [reSIProcate] how to send reINVITE with DUM ?

Hi:
I'm trying to make a little example program that implements the "Flow
IV" section in RFC3725 (3pcc).
The problem is that I can't find a way to send the reINVITE properly
(message number 6 in Figure 4).
I've found no place in DUM docs, wikis, forums, etc which tells me how
to send a reINVITE from a UAC.
I've tried these 2 approaches:
1) sending the INVITE and reINVITE to client "A" as in the basicCall
example in /dum/test:
dumC1->send(dumC1->makeInviteSession(client1Aor, 0, new
b2buaAppDialogSet(*dumC1, "Client1(INVITE)")));
This way doesn't work because client "A" thinks the reINVITE is a
"new" invite, and tells me the softphone is "busy" with the first one.
2) making a copy of the first INVITE, the SipMessage created by the
makeInviteSession() call. Then "sending" this SipMessage as reINVITE.
I manually set the SDP content of client "B" as the RFC indicates, and
also incrementes the CSeq number of the original message.
This way doesn't work, the example program asserts at
InviteSession.cxx:1515, telling that "DUM delivered a INVITE to the
InviteSession". The message traced at this point is: 481 Call
Leg/Transaction Does Not Exist.
Could anyone give me a hint about sending reINVITEs with DUM ?
thanks in advance....
Diego
Hi Diego,
Have you tried using InviteSession::provideOffer()?
