  • Apparatus and method for telephony feature access and gatekeeper policy interaction on combined ToL/PBX systems
    Patent number: 7245607
    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.

  • Method and system to provide telephony tones and announcements in a packetized network environment
    Patent number: 6456601
    Abstract: A method and a system of providing call progress tones in a packetized network include storing the call progress tones and pre-programmed audio deliveries at a first device and includes multicasting or broadcasting the tones and deliveries from the first device to a number of telephony-enabled devices. The multicasts are in a format that enable the telephony-enabled devices to individually control transmissions of the tones and deliveries to other devices, particularly calling devices for incoming calls. Typically, the audio deliveries include memory intensive signals, such as announcements and music-on-hold. The progress tones include conventional call status tones, such as ringback, busy and error tones. In one embodiment, the telephony-enabled devices are telephones to which the calls are directed. In another embodiment, the telephony-enabled devices include proxies that process the system-wide multicasts for telephones of the network.

  • Monitoring and controlling channels to improve the interface of calls
    Patent number: 5991387
    Abstract: A method is provided for monitoring channels and controlling calls. Multiple channels provided by at least one digital line are monitored. Based on this monitoring, the present invention determines when all of the multiple channels are occupied. At least one of an incoming call and an established call is given priority when all of the multiple channels are busy. The priority is based on predetermined inputs from a user. The call with priority is provided on one of the multiple channels. The present invention then determines when one or more of the multiple channels are available. When one of the multiple channels becomes available, the action based on the call priority is automatically disabled.
