Display line number on display

[CuriousSpyder]

Is there a way to be able to see what telephone line a caller is on on the display of the telephone? This would help determine which trunk is having a problem such as static, noise, low volume, dtc.

Thank you.

You could alway capture the SMDR and take a look at which line it is that way.

Give all your trunks a separate line ID.
Make shortcodes to force outgoing calls to use the trunk you want to test.
This would make 100% sure you know what trunk you are using for the call. And you can determine which trunk the static is on
