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.
