ABSTRACT:
A method of routing a request in a communication system. The method comprises searching routing information associated to an identity, and prioritizing either one of the routing information related to the identity for the first type and the routing information related to the identity of the second type. The request is then routed by using the prioritized routing information. The invention advances correct routing in a system where different identity types are available.
