[Asterisk-Users] x100p card - detect dialtone?

[Rich Adamson]

Does anyone know if there is a zapata.conf option to tell * to 
listen for a dialtone before dialing?

I've got a couple of analog phones on a pstn line shared with a
x100p * fx line. If someone is on the analog phone and another
person initiates a call through * to use the same line, * dials
over the top of the existing conversation. Is there a way to have
* detect dialtone before dialing?
