ABSTRACT:
A telecommunication network includes the first subscriber served by one type of telecommunication switch and a second subscriber served by a different type of telecommunication switch. A group affiliation parameter which defines an organization of which the first subscriber is a member is included in a call setup message. Upon receiving the call setup message at a telecommunication switch associated with a called second subscriber, a determination is made of whether the first and second subscribers are members of the same organization. Upon determining that the first and second subscribers are members of the same organization, call handling parameters associated with the first organization are used to process the call request to allow common control of such calls even though the first and second subscribers are associated with different types of telecommunications equipment.
