Abstract

In a telecommunications network having switching points (such as SSPs and/or MSCs) controlled by a control point (such as an SCP), the switching points are provisioned to send messages to the control point when they encounter trigger conditions during processing of a call to a called station that has a forward-to number. When the control point receives the messages, it determines whether a loop condition exists, i.e., whether the call has already been forwarded from the forward-to number. If the control point determines that a loop condition exists, the control point instructs the switching point so as not to forward the call to the forward-to number.
