[Asterisk-Users] Dialing dead SIP peers give misleading (BUSY) voicemail result ...

[Darren Nickerson]

Thanks for the helpful reply! Without using macros, the following works
well:

exten => 8102,1,DBget(sipcheck=SIP/Registry/${someone})
exten => 8102,3,Dial(SIP/someone,20)
exten => 8102,102,Voicemail(u8102)
exten => 8102,103,Hangup
exten => 8102,104,Voicemail(b8102)
exten => 8102,105,Hangup

Thanks also for the poke I needed to begin looking into macros. The sample
macro-stdexten (which you recommended customizing) looks like:

exten => s,1,Dial(${ARG2},20)
exten => s,2,Voicemail(u${ARG1})
exten => s,3,Goto(default,s,1)
exten => s,102,Voicemail(b${ARG1})
exten => s,103,Goto(default,s,1)

I don't see a way to add the DBGet check for a SIP registration in a generic
way ... if this is a Zap extension there won't be a registration but we
should still try to dial, right? Do I need a macro-stdZAPexten macro that
looks like the one above, and a macro-stdSIPexten that looks something like
(assumes my SIP naming scheme is based on extension number):

;
; ${ARG1} - Name of SIP peer to dial
;
exten => s,1,DBget(sipcheck=SIP/Registry/${ARG1})
exten => s,3,Dial(SIP/${ARG1},20)
exten => s,4,Voicemail(u${MACRO_EXTEN})
exten => s,5,Hangup
exten => s,102,Voicemail(b${MACRO_EXTEN})
exten => s,103,Hangup

in addition to the macro-stdexten one?
