Carrier Query Implementations for Asterisk PBX

Least-cost routing with carrier lookups

Integration of NumberPortabilityLookup with the Asterisk PBX enables you to route your outbound VoIP calls via the most cost-effective provider based on the network carrier of the mobile number being called.

Mobile Number Portability

Mobile Number Portability (MNP) (aka Wireless Number Portability or WNP) makes routing voice calls more complex than simply lookup up the prefix of the number (eg "07970 = Orange") - as mobile subscribers are now free to move (port) their service between wireless carriers, porting their phone number with them to their new network provider.
