Number Portability and ENUM Expert
Telephone numbers are legal, commercial and technical objects at the same time. A defensible analysis distinguishes allocation rights, portability data, routing logic and the network behavior that ultimately determines whether traffic reaches its destination.
Typical issues
- Number allocation and permitted use
- Portability database records and real-time lookup behavior
- ENUM query construction and response handling
- Routing after porting or reassignment
- Accessibility of number ranges across interconnected networks
Technical approach
- Reconstruct the authoritative numbering and portability record
- Map each lookup and routing decision to the responsible system
- Compare configuration with observed traffic
- Separate regulatory questions from implementation failures
Demonstrated industry involvement
Redworks and COIN implemented real-time CRDB ENUM lookups using portability data to improve routing decisions, reduce unnecessary transit and strengthen call quality. That operational experience informs analysis of numbering and routing disputes.
