The PJSUA-LIB, as the highest abstraction, is tied up with media (audio, in this case. video is coming though ;-), to make it easy to use, and currently does not support other media in the SDP (unless if you hack it of course). But if you work with the lower level invite session directly (see [1]), you have full control over the SDP content that will be negotiated by the session, so at this level any media in the SDP is supported.
