Ok, I might be misunderstanding you, but tell me if this helps;-

Have a look at some of the test apps like the sine wave generator.  
PJSip has kind of a patch bay architecture that lets you define end  
points (like audio devices, sip calls, tone generators) and lets you  
arbitrarily patch them into each other.

The sine generator is instructive in this case. It should be fairly  
straight forward to adapt that code into a generic end point template  
you can use to provide your own data stream.

You basically create an end point, register it, then use a call to  
patch it in via the conference bridge. Its a rather powerful arangement.
