Abstract
A broadband communication system including an Internet Protocol Telephony Network and public switched telephone network, including apparatus and methods for placing a call on hold in a way that significantly reduces the amount of network bandwidth utilized by the call while the call is on hold. When a call is placed on hold, embodiments of the architecture of the telephony network of the present invention allows the network to essentially 'forget' about the call placed on hold. In other words, a call that is on hold may require very little, or even zero, bandwidth within the telephony network. Accordingly, the total necessary bandwidth capacity of the telephony network may be smaller than it would be if calls on hold were to consume precious network bandwidth as is found in existing telephony systems.
