[Asterisk-Dev] What to do?

[m. smadi]

hi;

i have a conference room setup on the asterisk server. And say that one 
of the sip peers (say A) wants to dial outbound to a PSTN destination 
(say B).  Can i have A join the conference room and some how at the same 
time ask B to join the conference room?

If this is not doable in the current state of asterisk, any idea on 
how/where to implement that?
Any feedback is appreciated.

thanks
