In accordance with certain embodiments, disclosed herein is a method for shifting charges. The method includes receiving a request for a communication session between at least two endpoints. The request comprises a charging preference that indicates a request for a shift in at least a portion of the charges associated with the communication session. The method further includes transmitting a message to a charging system indicative of the request for the shift in charges based on the charging preference. The method additionally includes determining whether to establish the communication session between the at least two endpoints or to reject the communication session between the at least two endpoints. The method also includes, based on the determination, facilitating in the establishment of the communication session or the rejection of the communication session.

Shifting of communication session charges

A method of enabling configuration of a link between a circuit-switched Private Branch Exchange (CS PBX), and an access gateway node that connects at least one CS PBX to an IP Multimedia Subsystem (IMS). The method is performed at an IMS application server, AS. The AS is configured with timeslot configuration information for each link between the access gateway node and the at least one CS PBX. The AS receives, from the access gateway node, a request for timeslot configuration information for one or more of the links, and identifies the one or more links to which the request relates. The AS then retrieves the timeslot configuration information for the identified link, and sends a response indicating this information to the access gateway node.
