[reSIProcate] multipart/alternative content-type

[Diego Carvalho Domingos <ddomingos@xxxxxxxxxxxxxxx>]

Hi all,

How do I access multiple SDP’s of an INVITE which the content-type is multipart/alternative? In my case the INVITE contains two SDP’s and for some reason, the way I get the SDP is getting the second one. For instance, in the onNewSession method:
onNewSession(ClientInviteSessionHandle, InviteSession::OfferAnswerType oat, const SipMessage& msg)
I do:
SdpContents* contents = dynamic_cast<SdpContents*>(msg.getContents());

Why this is getting me the second one? How do I access the first one? I saw that there is a subclass of Contents called MultipartAlternativeContents but I don’t think this is the one returned by getContents because if so the dynamic_cast would fail.

I appreciate any help. Thanks in advance.
