[pjsip] multiple media in parallel?

I will try to put it differently.

>From what I can see 'pjsua_conf_connect' is used to join calls into a 
conference. But it doesn't return a distinct 'conf ID' or anything like 
that. I want conferencing features like holding multiple conferences, 
conference hold, adding a call to a particular conference. From my 
understanding, work needs to be done to implement the said features using 
PJSIP-LIB functionality.

Am I correct here?
