A method and arrangement in a telecommunication network according to "GSM on the Net" or "IPT" intercepts an incoming call for a user registered at an access node for which an intercept service is active. Depending on the type of called party identifier provided with the incoming call, the call is routed to the Service Node. The service node identifies an alias of the access node and sends the access node alias with called party data to the application node. The application node returns to the service node a divert-to identifier associated with the access node, and the service node delivers the call to a different access node identified by the divert-to identifier.
