Failed tone instead of busy

matrix8086 used Ask the Experts™

I have an Elastix server with Grandstream 1165 IP phones. I have disabled the waiting calls. When a busy extension is called, the caller is receiving a failed tone (the display it shows "failed" too ) instead of busy tone (the display it must shows "busy" also)

Anyone knows the problem?

Best regards!

The problem appears after an Elastix update and the developers consider it as a feature. But for me and my colleagues is annoying. That's life!
