How to Troubleshoot VoIP Phones That Show the Wrong Caller ID

Caller ID can be set by user profile, PBX route, carrier policy, or number presentation configuration.

Checks to make

Capture the call direction, extension, destination, time, and provider reference. Compare the configured outbound identity with carrier settings, test another route, and confirm authorized numbers with the provider before changing production caller ID.
