Abstract
Methods and systems for determining call types are described herein. An intelligent node is configured to determine whether a call is a mobile-to-mobile call between subscribers of a telecommunication service provider based on a response to a request from the intelligent node. The intelligent node may further be configured to send a state request to an interconnecting network of the telecommunication service provider. A node of the interconnecting network determines whether a serving subscriber identifier is included in a routing database of that node. If the identifier is not included, the node responds with an error message. If the identifier is included, the node communicates with a relay function and responds to the request with a state received from the relay function. The intelligent node may also be configured to send an ENUM query and receive an identifier of the telecommunication service provider associated with the serving subscriber.
