Hi folks,
Im not able to get inbound callerid working with a 2811 and vic2-2fxo. Im using CME ver7.
I also have a 1751v with vic-2fxo-m1 that is working with callerid.
voice-port 0/0/0
connection plar opx 1001
caller-id enable

Caller-id can delivered differently by each carrier, I had a similiar issue and discovered that the telco was using polarity line reversal.
In this scernario, an FXO interface cannot detect line-reversal alerting in the on-hook state.
For this reason, DSPs must be pre-allocated to serve the Type 1 caller ID information when it arrives.
Preallocating the DSPs enables the DSP to continuously monitor for the arrival of caller-ID information.
Configure this command 'caller-id alerting
dsp-pre-alloc' on the FXO port when the incoming subscriber telephone line uses line polarity reversal to signal the start of caller-ID information transmission.
If you debug vpm signal, this should give you an indication in the debug if line-reversal is being used by your telco. Below is a debug example:-
If CLID enabled and line-reversal, the you should see a similar debug as follows:-
