M4 MNP Carrier Groups
Description
Using Mobile Number Portability (MNP) to route calls, The MNP database returns a Carrier Identification Parameter (CIP) for ported subscribers (this information is stored in the MNP database column set in Result field in settings page).
One or more codes together form a Carrier Group.
Carrier Group can be assigned to Termination Point, as part of the Mobile Number Portability routing algorithm to select the destination for MNP calls.
TP with Carrier Group is matched with the CIP Carrier Group. If a match is found TP is validated for this call. In other words - only selected TPs can serve MNP Numbers.
Configuration
MNP Carrier Groups can be found in the menu Routing -> MNP Carrier Groups. This menu is available only if Mobile Number Portability' is enabled in settings page.
Here you can create/delete Carrier Groups and add/delete codes to/from them.
The same code can be added to more than one Carrier Group.
