[asterisk-users] answer machine detection

[Julian Lyndon-Smith]

great help. Thanks for that Matt.

One thing that is really confusing me at this point: if I want to leave 
an automated answer machine message, and amd tells me it's a machine, 
how do I know when to start leaving the message ? Some "intros" are long 
(thanks for calling, me and mine are not here right now, please leave a 
message after the beep) and some are short "Leave a message".

Is there a way of waiting in the dialplan for a beep or something like 
that ?

Julian.
