Implementiert eine extrem simple Queue. Zu einer Dialgroup kann man mit der operation add Mitglieder hinzufügen, und mit del kann man diese entfernen. Ohne Angabe einer operation wird die gesamte Liste der Mitglieder durch den neuen Wert ersetzt.
exten => 123,1,Set(DIALGROUP(beispiel,add)=SIP/108)
exten => 123,n,Set(DIALGROUP(beispiel)=SIP/109)
exten => 123,n,Set(DIALGROUP(beispiel,add)=Local/105)
exten => 123,n,Set(DIALGROUP(beispiel,add)=SIP/104)
exten => 123,n,Set(DIALGROUP(beispiel,del)=Local/105)
exten => 123,n,Set(DIALGROUP(beispiel,add)=Local/102)
exten => 123,n,Set(DIALGROUP(beispiel,add)=Local/101)
exten => 123,n,Verbose(1,Gruppe ist: ${DIALGROUP(beispiel)})
exten => 123,n,Dial(${DIALGROUP(beispiel)})
exten => 123,n,Hangup()
Effektiv entspricht das einem:
exten => 123,1,Dial(SIP/109&SIP/104&Local/102&Local/101)

  -= Info about function 'DIALGROUP' =-


Manages a group of users for dialing

  DIALGROUP presents an interface meant to be used in concert with the Dial
application, by presenting a list of channels which should be dialled when
  When DIALGROUP is read from, the argument is interpreted as the particular
group for which a dial should be attempted.  When DIALGROUP is written to
with no arguments, the entire list is replaced with the argument specified.
Other operations are as follows:
  add - add a channel name or interface (write-only)
  del - remove a channel name or interface (write-only)

Functionality is similar to a queue, except that when no interfaces are
available, execution may continue in the dialplan.  This is useful when
you want certain people to be the first to answer any calls, with immediate
fallback to a queue when the front line people are busy or unavailable, but
you still want front line people to log in and out of that group, just like
a queue.
