ok.

Let's say that you call from 1011 to 1010.. Witch extension rings? Other than 1010??? If so paste some output from cli?

Thanks, i solved the problem. It was i telephone error, which takes some configuration from other. As soon as we connect the phone to the network, A chaos was shown.

no prob

Glad you solved it!
