I tried this a few times and updated the firmware etc but I still can't get callerid. I'm on a BT line.

I have tried using the above command to enable CLID on my BT line on my 2820 PBX..

Does anyone have any idea why the above command line is not being accepted as a valid entry via telnet on the latest firmware??

I have checked and I am typing it correctly but keep getting thrown back the usual "valid entries for this command are blah blah blah" response...

HELP.. I miss my CLID....
