[pjsip] Custom INVITE sessions (for file transfer for example)

And would it be possible that still PJSIP handles the INVITEs for voice calls while the application handles the INVITEs for file transfer? As I understand, the application will get the SDP of every INVITE (including the voice calls) and it can recognize whether this is a file transfer INVITE or not, and if this is not the file transfer INVITE can the application just let PJSIP process it by default, not having to deal with the audio channels, etc?

I think it should be possible with using PJSIP API (not PJSUA-LIB
API), although I haven't tried this myself. You need to manually
construct an SDP containing the file transfer descriptor, create
invite session and give the SDP to it. Once SDP is negotiated
on_media_update() will be called and you can retrieve the negotiated
SDP's from both local and remote party and do the file transfer.
