[Asterisk-Users] zap device detects hangup when phone switches from answer machine announcement to recording

[Martin Renschler]

Hi,
I have a Panasonic Cordless phone and want to use the built-in answer 
machine instead of an asterisk voice mailbox. The problem is now that 
the answer machine plays the announcement and exactly when it wants to 
record, asterisk reports a zap Hangup. The caller never even hears the beep.
Any idea what is going on, any parameter in the zap config files that 
would fix that?
Thanks
