First Claim
1. A method in a communication network for connecting at least one application server (AS) of an internet protocol multimedia subsystem (IMS) to an intelligent network (IN) through an interface unit, wherein the IMS comprises a call server control function (CSCF) unit connected to the at least one AS arranged for processing call signaling, wherein the method comprises the following steps with respect to a call:
- the interface unit directing call signaling to the at least one AS through the CSCF unit;
the at least one AS processing the call signaling and sending the processed call signaling through the CSCF unit back to the interface unit; and
based on the information received in the call signaling processed by the at least one AS, the interface unit directing the incoming call to a destination.

Abstract
The present invention relates to a method in a communication network for connecting at least one application server (AS) (213) of an internet protocol multimedia subsystem (IMS) (200) to an intelligent network (IN) (100) through an interface unit (301). The IMS (200) comprises a call server control function (CSCF) unit (205) connected to the at least one AS (213) arranged for processing call signaling. In the method the interface unit (301) directs the call signaling to the at least one AS (213) through the CSCF unit (205) and the at least one AS (213) processes the call signaling and sends the processed call signaling through the CSCF unit (205) back to the interface unit (301). Based on the information received in the call signaling processed by the at least one AS (213), the interface unit (301) then directs the call to a destination.
