Data and call routing and forwarding

摘要

One or more aspects of the disclosure relate to various functions and processes related to routing of calls originating from other service providers. For example, a method includes receiving a request to route a call or a call session, such as a session initiation request, from a second service provider and proceeding to route the requested call or session through a call routing facility of the first service provider to a requested destination of the call. Routing the call through the call routing facility may include determining a service provider type and/or an origination number type for the call, determining routing information for the call using the type information, and causing routing of the call to a destination of the call based on the routing information. Further aspects of the disclosure relate to various functions and processes related to accessing routing data and/or information from a routing database.
