waiting call signal (possible?)
Posted on 2011-03-11
I am using ELASTIX (FreePBX) wrapper of Asterisk 220.127.116.11 and on other machine Asterisk 18.104.22.168.
I want to make the caller hear a waiting call beep when he calls to an extension which is on call. Currently there is an option to enable "waiting call" when the caller just hear regular calling beeps, or to disable "waiting call" and then the caller just hear standard "busy" tone.
How is it possible to implement a "waiting call" tone which the caller will hear while the callee sees a "waiting call".
