Sure! Otherwise why would we bother to have the conference bridge if 
we only support 1 call? ;-)

The comment says "we can only support one stream per (media) 
*session*", meaning 1 stream per call. It does not support, e.g. 
audio and video streams on a single call, yet.

So there must be something wrong that you did that prevented 
pjsua-lib from creating the second call.
