; Standard behavior for calling an extension

; Standard extension macro:
;   ${ARG1} - Extension  (we could have used ${MACRO_EXTEN} here as well
;   ${ARG2} - Device(s) to ring
;   -->Note this assumes extension is same as mailbox number
;
exten => s,1,Dial(${ARG2},20)		; Ring the interface, 20 sec
exten => s,n,Goto(s-${DIALSTATUS},1)	; Jump based on status

exten => s-NOANSWER,1,Voicemail(${ARG1},u)	; If unavail send to vm unavail
exten => s-NOANSWER,n,Goto(default,s,1)		; If press #, return to start
exten => s-NOANSWER,n,Hangup

exten => s-BUSY,1,Voicemail(${ARG1},b)	; If busy, send to vm busy 
exten => s-BUSY,n,Goto(default,s,1)	; If press #, return to start
exten => s-BUSY,n,Hangup

exten => _s-.,1,Goto(s-NOANSWER,1)	; Treat anything else as no answer

exten => a,1,VoicemailMain(${ARG1})	; If press *, send to VoicemailMain
