[Asterisk-Users] Why don't I get a ringing sound?

[Paul Mahler]

I am using the following macro to dial a ZAP channel. When I dial in, *
answers and I go to voicemail. I never hear any ringing, though. It doesn't
work with the Ringing command before or after the Dial command. 

[macro-zapdial]
;
; call a ZAP extension for ${ARG2} seconds, and then voice mail
;   ${ARG1} - Extension
;   ${ARG2} - Time to ring
exten => s,1,Dial(ZAP/${ARG1},${ARG2})
exten => s,2,ringing
exten => s,3,Voicemail(u$[${ARG1} + 99]) ; match the channel to the mailbox
exten => s,4,Goto(${ARG1},1) ; If they press #, return to start
exten => s,104,Voicemail(b$[${ARG1} + 99])
exten => s,5,Goto(${ARG1},1) ; If they press #, return to start

Here is what the log shows: 

-- Zap/1-1 is ringing
