摘要:
Fault tolerant VoIP systems and methods to operate the same are disclosed. An example method comprises receiving a registration request at an edge device of a voice over Internet protocol (VoIP) system from a user device, selecting at the edge device a communication service providing device from a list of devices configured to provide communication services, sending the registration request to the selected communication service providing device, and receiving a registration response from the selected communication service providing device.

Methods and apparatus for load balancing in communication networks are disclosed. An example method to perform load balancing in a communication network disclosed herein comprises routing a registration request received for a user device in an Internet protocol multimedia subsystem network to a first call processor when the user device is registered with the first call processor and in an active call session with the first call processor, and querying a load balancer to determine whether to assign the user device to at least one of the first call processor or a second call processor when the user device is registered with the first call processor but not in any active call sessions with the first call processor.

摘要:
Example systems and methods to manage location information for emergency services support of an internet protocol (“IP”) communication device are disclosed. A disclosed example method involves storing first and second geographic location information in a first list of geographic location information associated with an internet protocol device. The first list is stored at a service provider server. At least a partial copy of the first list is communicated from the service provider server to the internet protocol device for storing as a second list of geographic location information in the internet protocol device.

摘要:
An apparatus and method are disclosed for processing a communication request from a roaming VoIP terminal. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive from a Voice over IP (VoIP) terminal a request to communicate with a destination point, wherein the request comprises an identification (ID) of the destination point, an ID of the VoIP terminal, and a media access control (MAC) address of a gateway providing the VoIP terminal communication access to the network proxy, and determine from the MAC address of the gateway and the ID of the VoIP terminal whether the VoIP terminal is roaming outside of a home network. Additional embodiments are disclosed.
摘要:
Methods and apparatus to provide voice communication inoperative condition notifications are disclosed. An example method includes detecting an inoperative condition associated with a called voice over internet protocol device, comparing the inoperative condition to a criterion, and forwarding an inoperative condition notification for display on a display device associated with the called voice over internet protocol device when the criterion is satisfied.

摘要:
Example methods and apparatus to control synchronization in voice over Internet protocol (VoIP) networks after catastrophes are disclosed. An example border element comprises a network interface to receive a VoIP network registration request message from a VoIP endpoint, a catastrophe detector to determine whether a catastrophe has been detected, a backoff time module to compute a backoff time using a priority assigned to the VoIP endpoint and an expected number of VoIP network registration request messages, a recovery module to determine whether the VoIP endpoint is currently registered with the VoIP network, and to send a response message having a header representing the backoff time to the VoIP endpoint when the catastrophe has been detected and the VoIP endpoint is not currently registered with a VoIP network, and a signaling processor to process the VoIP network registration request message when the VoIP endpoint is currently registered with the VoIP network.
