[reSIProcate] Invite without SDP

["Rodrigo Alcoberro" <ralcoberro@xxxxxxxxxxxxxxxxxx>]

Hello,
I´m developing a B2BUA in a system that must able to perform mid call 
announcements. I´m following the RFC3725 (Best Current Practices for Third 
Party Call Control ...), and I need to send a Invite without SDP. It goes OK, 
but when the provisional response 180 arrives a exception occurs in DUM.
I see the problem is DUM tryes to create a ClientInviteSession with a pointer 
to "initialOffer" SDP (ClientInviteSession.cxx line 20) and the pointer is 0 
because no SDP was offer.

I don´t know if it is a bug or I´m not using the library well.


Did someone try use the library in this scenario ?  

Thanks in advance
Best regards
