Hello everyone, I have a little problem that I want to share and see if someone can give me a hand on this. Here it goes.
I have a system with 4 FXO lines, and couple of IP phones connected to the server, the company that provides us with the analog lines for the FXO ports is a low quality company and most of the time when a call is made in one of the ports a busy tone is heard and then you have to keep trying until the call gets through. What is needed to do is to fix the dialplan that if it sense a busy tone in the called line to jump to the next FXO channel. How can I accomplish this.
Thanks in advance.
