[Asterisk-Users] Detect phone pickup, caller ID AGI

[Kevin DeGraaf]

Hello all,

I have Asterisk running as a simple voicemail server.  I don't have any 
FXS ports, IAX/SIP clients, anything like that, just an X100P attached 
to my phone line in parallel with a number of "normal" phones.

I have a Wait(18) command in my dialplan which works fine; Asterisk 
picks up after four rings and proceeds to record voice mail.  However, 
if I pick up one of the "regular" phones, Asterisk still proceeds.

Can my X100P/Asterisk solution detect a phone pickup and abort, just 
like a "normal" answering machine would do?

Also, is it possible to set up the dialplan such that an AGI is always 
called, regardless of whether another phone is ever picked up, as soon 
as Caller ID data is available (via a method more elegant than a Wait 
statement)?

(I'm interested in having MythTV display the Caller ID information upon 
an incoming call, as soon as Asterisk has decoded it.)
