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.

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.

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:
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:
A method, a system and a computer readable medium for routing packets across disparate networks are disclosed. For example, the method receives, via a media gateway controller (MGC), an external request from an external requestor for a reservation of a public switched telephone network (PSTN) trunk on a media gateway (MGW) for a communication session between a voice over Internet protocol (VoIP) network and a PSTN network, sends, via the MGC, a H.248 request to the MGW to make the reservation, establishes via the MGW, a communication path and sending a message to the MGC, retrieves, via the MGC, an assigned Internet protocol (IP) address and IP port on the MGW from the message from the MGW, sends, via the MGC, an allocation request to a media terminating session border controller (SBC) and allocates, via the media terminating SBC, a public IP address and a public IP port from an available pool of IP addresses and IP ports at the media terminating SBC.
摘要:
A system that incorporates teachings of the present disclosure may include, for example, an edge device having a controller to receive a Session Initiation Protocol (SIP) message from a user endpoint device (UE) requesting communication services, forward the SIP message to a network element of a Server Office, receive from the network element a first error message indicating communication services at the Server Office are unavailable, replace the first error message with a second error message, the second error message indicating a temporary unavailability of communication services, and transmit the second error message to the UE. Additional embodiments are disclosed.
