This is just a plain old bad idea, especially if your caller id is not 
consistently and religiously set up.  It seems like you're trusting the 
phones too much.

Personally, my voicemail stuff looks a little like this:

exten => _*98XXX,1,VoiceMailMain(${EXTEN:3}@default)
exten => *97,1,GotoIf($[${LEN(${CALLERID(num)})} == 3]?good)
exten => *97,n,Set(VMBOX=)
exten => *97,n(done),VoiceMailMain(${VMBOX}@default)

and then the standard extension:
; if VOICEMAILTO is set, send voicemail to there instead of ${ARG1}
[macro-stdexten]
exten => s,1,GotoIf($[ "${VOICEMAILTO}" != "" ]?vmto)
exten => s,n,Set(VOICEMAILTO=${ARG1})
exten => s,n(vmto),Dial(${ARG2},20,g)
exten => s,n,GotoIf($[${DIALSTATUS} = BUSY]?busy)
exten => s,n,GotoIf($[${DIALSTATUS} = CONGESTION]?busy)
exten => s,n,GotoIf($[${DIALSTATUS} = ANSWER]?done)
exten => s,n,Voicemail(${VOICEMAILTO}@default,su)
exten => s,n,Goto(done)
exten => s,n(busy),Voicemail(${VOICEMAILTO}@default,sb)
exten => s,n(done),Hangup

The phones (polycom in my case) are set that vmcallback is *97, and *98XXX is 
used more for administrators and DISA-style applications.
