[Asterisk-Users] Is this possible?

[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? 

I think this feature is very important, because if we have few people in 
a conference room, it would be very nice to invite people to join the 
conference without the need of putting everybody on hold.

Any feedback is appreciated.

thanks
