Route Selection Source Name and Route Selection Name

A route selection source name is the name of the classification of the outgoing route selection policy configured for a call source. A route selection source name maps a call source. When different outgoing route selection
policies are configured for different subscribers of an MSC, different route selection source names can be defined for different call sources. A route selection source name is configured in the Call Source table (ADD CALLSRC).

A route selection name is the name of the route selection policy code configured for calls to called numbers with a specific prefix. During route analysis, a route selection name and a route selection source name co-dertermine an outgoing route. The route selection name is configured in the Route Analysis table (ADD RTANA).
The route selection source name is set for callers, and the route selection name is set for callees. Through the setting of route selection source names, different outgoing routes can be selected for the same route selection name.
