How to Troubleshoot VoIP Phones That Show the Wrong Caller ID

11/10/2026

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.

When to get help

Voice support can trace caller ID presentation through PBX and carrier. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
