ring back trunk internal extension response?

It is because of the mismatch of signaling.

Please select
“Trunk”->”Analog Trunk”,
and change the value of “Caller ID Start” and “Caller ID Signaling” in the editing page.

In most cases, the problem could be solved by changing the value of “Caller ID Start” from “Ring” to “Polarity” . But if not, please change it to other option.
