M4 Local Number Portability allows to connect to Local Number Portability (LNP) database and retrieve information about destination number local portability status (routing number).

LNP DB should be MySQL compatible, required DB fields are described in M4 settings page.


Jurisdictional routing is telephone call routing logic based upon the locations of the calling and called number and regulatory considerations. Jurisdictional routing can be divided into three main parts:

  • Intrastate routing (Intra) - calls within the same state.
  • Interstate routing (Inter) - calls from one state to the other.
  • Indeterminate routing (Indeter) - calls where origination information cannot be determined (for example, calling number is not a valid number).

More information about Jurisdictional routing can be found in this whitepaper.

Jurisdictional routing is activated (activated means it can be enabled/disabled) once LNP Database is configured in M4 settings page.

Once LNP DB is configured, Jurisdictional routing can be enabled in the Origination Point settings.
