Hi all, we are running Asterisk SVN-branch-1.4-r114299 and face following problem: we have a main extension (102) and other extensions (104 and 107) When extension 104 is calling extension 107 and 107 is on the phone, the caller is parked for 5 seconds (Park-And-Announce) and the going back to the called extension (busyNUMBER). After 6 loops in busy state, the call has to be forwarded to main extension which is 102. Everything is working perfectly with one call is this loop. If a second call enter this loop, the busyNUMBER is replaced by the last asked extension, even for calls already in the loop! I was expecting that one call -here SIP channel- is one channel so variables and their values are independent of the concurrent calls in this channel. the busyNUMBER is _not_defined as a global variable and is unique in the dialplan. Is this behaviour normal or related to ParkAndAnnounce? Another solution would be to create an unique variable like (tested but it's not working): exten => _X.,1,Set(busyNUMBER=${UNIQUEID}) exten => _X.,n,Set($[${busyNUMBER}]=${EXTEN}) Is something like this existing? Thanks for your feedback. Relevant part of the dialplan is: [dial-local] exten => _X.,1,Set(GLOBAL(__DIALEDNUMBER)=${EXTEN}) exten => _X.,n,Set(busyNUMBER=${EXTEN}) exten => _X.,n,Set(VoiceMail=u) exten => _X.,n,Set(StatusPrio=1) exten => _X.,n,macro(rec,) exten => _X.,n,GotoIf($["${DIALEDNUMBER}" = "${CALLERID(number)}"]?extendedVM) exten => _X.,n(BackFromBusy),Dial(SIP/${DIALEDNUMBER},${SIPTIMERING},${DIALOPT}) exten => _X.,n,Goto(onDialStatus-local,s-${DIALSTATUS},${StatusPrio}) exten => _X.,20(extendedVM),NoOp(User ${CALLERID(number)} enter extended voicemail) exten => _X.,n,StopMonitor exten => _X.,n,VoiceMailMain() exten => _X.,n,Hangup exten => _70[1-9],1,ParkedCall(${EXTEN}) [onDialStatus-local] exten => s-BUSY,1,Set(VoiceMail=b) exten => s-BUSY,n,Set(CHANNEL(LANGUAGE)=fr) exten => s-BUSY,n,Set(countParkedLoop=0) exten => s-BUSY,n,Background(busy-pls-hold) exten => s-BUSY,n(AfterAnnounce),Set(countParkedLoop=$[${countParkedLoop}+1]) exten => s-BUSY,n,GotoIf($["${countParkedLoop}" < "7"]?:ReturnToMainLoop) exten => s-BUSY,n,ParkAndAnnounce(pbx-transfer:PARKED|5|SIP/${busyNUMBER}}) exten => s-BUSY,n,Set(StatusPrio=AfterAnnounce) exten => s-BUSY,n,Goto(dial-local,${busyNUMBER},BackFromBusy) exten => s-BUSY,n(ReturnToMainLoop),Goto(dial-local,102,1) -- Daniel
