The present disclosure is directed to a method and system to forcibly unregister and/or prevent registration of a gateway and/or other endpoint in a network region in response to a survivable gatekeeper servicing the network region becoming active.

Method to block split phone and gateway registration

Methods and systems for allocating licenses to devices are provided. More particularly, the devices included in a system may each require a license having a release value that is equal to or greater than the release value of the device in order to be fully operational. Upon the unregistration of a device, the highest cost or value license that can be made available while maintaining proper registration of the remaining registered devices is freed. More particularly, the difference between the number of devices registered and the licenses used is calculated for each release value. A variance for each release value, beginning with the least cost or lowest release value license and working towards the highest cost or value license is then calculated. The highest cost license that can be released is equal to the license value for which the calculated variance is equal to zero.

Method and apparatus for assigning and releasing licenses

The present invention is directed to load balancing call signaling channels at the times that they are established, the use of variable frequency keep alive mechanisms depending on the state of the call signaling channel, and the establishment of a call signaling channel when resources are available or otherwise based on need.

Efficient load balancing and heartbeat mechanism for telecommunication endpoints

Techniques for determination of endpoint Internet Protocol (IP) address assignment in an Internet telephony system are disclosed. In conjunction with the establishment of a voice path between an endpoint and a gatekeeper in the Internet telephony system, a virtual address assigned to the endpoint in a network address translation operation is determined. The virtual address is then communicated to the endpoint as part of or otherwise in conjunction with a registration process prior to establishment of the voice path such that the registration process can complete successfully despite the network address translation operation. Advantageously, the invention overcomes problems associated with voice path registration failures resulting from network address translation in a router, virtual private network (VPN) gateway or other similar network address translation device.
