Is there a way to find out what the Caller ID is processed as in SIP?

All my google searches keeps coming up with "Call ID" which is not what I need. I have a customer complaining that the "Caller ID Number" is incorrect on outbound calls.
So when they call out to someone, the wrong number displays. However, everything is programmed right. I pulled a PCAP from our network, but I can't seem to find the filter that would show me the number that is actually being sent.

Can someone help me with the filter for the Caller ID (or at the very least Caller ID Number)?

Does sip.from.user or or answer your question? But then the question becomes, what's between the originator of the call and the recipient? What does the SIP gateway do? Can you get a capture from 'the other side'?

I know for a fact that my number will be masked on outgoing calls to our group. You have to know all activve parties in th chain to know what is happening. but they mey be out of your span of control.
