Tim,
I use the following in my dialplan to distinguish between Unavailable (ie:
did not answer), Busy and  Channel doesn't exist.  ChanisAvail goes to
n+101 if the channel is NOT avail.  There is probably a better way to exit
the sequence but that is what works for me.

exten => 11,1,Macro(stdexten,11,SIP/11)

Below is the macro for the above... Have tested it with IAX2, SIP and MGCP.
The first argument is the macro name, 2nd is the voicemailbox, 3rd is the
Channel to dial.

[macro-stdexten]
exten => s,1,ChanisAvail(${ARG2})
exten => s,2,Dial(${ARG2},20,Ttr)
exten => s,102,Voicemail2(u${ARG1})
exten => s,103,Hangup
exten => s,104,Voicemail2(b${ARG1})
exten => s,105,Hangup

LIke I said.. its messy but does work.
