[Asterisk-Users] How to configure asterisk to emulate FXO signaling ?

[Carlos Munoz]

I'm unable to configure asterisk to provide dial tone, busy tone, detect 
dtmf digits, etc to an analog phone connected to a FXS port. 
Unfortunately, this particular  hardware does not provide FXO signaling. 
Incoming calls work perfect, the phone rings and voice flows on both 
directions. However, I can't place outgoing calls, there is no dial tone 
and dialing out makes no difference.

Does anyone know how to configure asterisk to emulate FXO signaling or 
point me in the right direction ?

Thanks,
