How to Investigate VoIP Calls That Fail After a Phone Number Port

Porting can affect inbound routing, caller ID, emergency location, or provider provisioning at different times.

Checks to make

Confirm port completion with both providers, test inbound and outbound calling from multiple networks, and record call references. Check number assignment, route propagation, and emergency-service address records before retiring the old carrier path.
