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.
