Wireshark - trace Caller ID

[LiveRock]

Hi

I am new to Wireshark. I use it to sniff on the traffic to debug but it creates a gigantic load of data.

Newbie question: How to track 3CX specific data or filter the caller ID when I know the caller ID number?

I tried the filter but is just says it is not a protocol, etc.

Surely appreciate some tips .....

Thank you very much..
