[reSIProcate] Re-INVITE without SDP

[Rodrigo Alcoberro]

Thank you for the prompt answer Scott,
I´m trying to add this capability because is very usefull for us. The re-INVITE message goes without SDP now but I think the state machine keep in a "offering" (wrong) state. I´m viewing it in detail just now.
Please let me know if you have any comments or suggestions.

Also, I have seen that the resiprocate release (0.9.0-5019) had a problem with the initial INVITE without SDP, I fixed it doing in
ClientInviteSession.cxx, Line 32 (inside ClientInviteSession constructor)

	if(initialOffer)
		mProposedLocalSdp = InviteSession::makeSdp(*initialOffer)


Then, If const SdpContents * initialOffer == 0 don´t construct the SDP.
I´m have been using it for a month.


Thank you very much
Rodrigo
