[macro-superdial]
; add some abilities to Dial(Technology/resource[&Technology2/resource2...][|timeout][|options][|URL]):
;	${ARG1} - Technology/resource[&Technology2/resource2...]
;	${ARG2} - timeout
;	${ARG3} - options
;	${ARG4} - URL
;	${ARG5} - Group
;	${ARG6} - Max. group number
;	${ARG7} - Caller ID name (typically for outgoing calls only)
;	${ARG8} - Caller ID number (typically for outgoing calls only)
;	${ARG9} - CDR account name (over-rides account group setting in sip.conf or iax.conf)
;	${ARG10} - voicemail to send to if noanswer (typically for incoming calls only)
; Usage instructions:
; 	for an outgoing call, in extensions.conf you just list multiple lines like: 
;		exten => s,1,Macro(superdial,IAX2/voipjet/${tfnumber},,,,voip,${MAXVOIPCALLS},,,voipjet) 
;		exten => s,2,Macro(superdial,IAX2/alpeh-com/${tfnumber},,,,voip,${MAXVOIPCALLS},,,aleph) 
;	and it will take the first one that is available
;
;	it also works for incoming like so .. 
;		exten => s,3,Macro(superdial,${PHONE1},15,Ttm,,pstn,${MAXPSTNCALLS},,,,u${GENERALVM})
;		exten => s,4,Macro(superdial,${PHONE1},15,Ttm,,pstn,${MAXPSTNCALLS},,,,u${GENERALVM})
;		exten => s,5,Voicemail(b${GENERALVM})
;	and then goes to unavailable voicemail if one times out .. otherwise (eg if busy) it tries the next extension 
;	if all are busy or unavailable .. it gets to the last priority which is the busy voicemail
;
