Changing Scenarios- Pricing and Routing Issues
Until recently, voice offering, routing, pricing, and billing were made mostly based on the phone number prefix. This means that porting phone numbers from one Voice Carrier to another did not affect call completion.
This is now changing, with prices depending on the network the phone number was ported to or on the geographic zone originating the call.
Hence, being able to resolve the portability issue becomes critical for Voice Carriers.
