Hi,
In a system with multiple SIP trunks assigned to the same SIP carrier, the system needs to be able to determine which service is calling the SCMC, it does this by matching the number in the SIP message from the carrier, with the number in the "Use Number" Field.
However, in the current SW, the "Use Number" field can only contain one number range.
The way to configure this system is create multiple System Routes to the carrier, each Route will have the Multiple registration feature enabled, and the number range assigned to that Route added to the "Use number" range.
A number range is typically a 100 number range xxxxxxxx00 to xxxxxxxx99. In a country with variable length numbers, you might need lots of routes.
The associated DDI numbers also have to be assigned to the DDI table.
