[asterisk-users] Knowing when an answerphone answers

[Nic Hughes]

Hi all,

I have found that when I use an announcement at the start of the call it 
results in a useless answerphone message if the call goes onto 
answerphone for any reason - the message being a chopped off version of 
the announcement.

Does anyone know of a good way to detect that an answerphone has 
answered - or how to detect the tone that they typically use so I can 
code around this (with a different message).

Thanks, Nic
