Abstract
A system and method for providing an on-hold call with a selectable continuous tone source using a service node, comprising a service switching point of a central office connected to a service logic program provisioned on a service node. Using the capabilities of the service node, the service logic program plays a continuous tone through a permanent trunk line connecting the service node to the service switching point. When the service switching point puts a call on hold, the service switching point connects the call through the permanent trunk line to the service logic program that is playing the continuous tone. As a result, the caller hears the continuous tone while the service switching point has the call on hold. In addition, the present invention provides a dual tone multifrequency administrative interface on the service logic program of the service node, which enables a customer to dial the interface, enter a passcode for access, and then choose between a variety of tone types such as a dial tone, a busy signal, a normal ring tone, a reorder signal (fast busy signal), a continuous busy signal, and a continuous ring tone.
