I'd like to make a dial plan but couldn't work it out. I'd be appreciated if you can help me. The client reaches asterisk by PRI and starts conferance by the SIP agent dedicated to his number. besides, I want to add another second client who dialed the same number to the first client's conferance by the SIP agent. the point is this: I call from PRI with SIP agent by the dial but they start the conferance without entering the conferance room. when 2 call come enters the conferance room being aware of that the SIP is busy. I need to meet the calls and SIP in the same conferance room. Here is my current Conferance Dial Plan [conferance] exten => _XXXXXXXXXX,1,Ringing(10) exten => _XXXXXXXXXX,2,Answer exten => _XXXXXXXXXX,3,SetGlobalVar(numara=${EXTEN}) exten => _XXXXXXXXXX,4,Dial(SIP/${EXTEN},30,m) exten => _XXXXXXXXXX,5,Goto(${numara}-${DIALSTATUS},1) exten => _XXXXXXXXXX,6,Meetme(${numara}) exten => _XXXXXXXXXX-BUSY,1,Meetme(${numara}) exten => _XXXXXXXXXX-ANSWER,1,Meetme(${numara}) exten => _XXXXXXXXXX-NOANSWER,1,Playback(jingle) exten => _XXXXXXXXXX-NOANSWER,2,Hangup exten => _XXXXXXXXXX-CHANUNAVAIL,1,Playback(jingle) exten => _XXXXXXXXXX-CHANUNAVAIL,2,hangup
