Abstract
A ToL/PBX system is provided whereby a single policy may be enforced for both TFA (telephony feature access) and ToL (telephony over LAN) users by making the H.323 gatekeeper (103) aware of those TFA connectors so as to accurately allocate the remaining available bandwidth. According to one embodiment of the invention, the H.323 gatekeeper (103) is notified whenever a TFA call is being made or received.
