[asterisk-users] Detecting sound before answer

[Mindaugas Kezys]

Hello,

 

Let's say I'm dialing out and before channels are bridged I hear "beep" or
something similar. That way I know I'm calling to other Telco/Provider.

 

Is it possible to detect that "beep" before channel is answered and to
redial through other trunk?

 

 

Regards/Pagarbiai,
