Abstract

Systems and methods for dynamically registering a communication device are disclosed. As one example, a communication network architecture is disclosed that includes multiple feature servers, multiple registration redirect servers (RRSs), and multiple communication devices. The feature servers provide services to the communication devices. The RRSs each service a shared virtual Internet Protocol (IP) address and perform load balancing of registration requests on behalf of multiple feature servers located geographically proximate to the RRS. The communication devices are configured to issue initial registration requests intended for any of the feature servers to the shared virtual IP address, whereby upon issuing an initial registration request, a communication device is directed to a particular feature server that is associated with a RRS that is closest to the communication device, and where the particular feature server is selected by a load balancing routine executing on the RRS.

Claims

1. A method comprising:

responsive to receiving a service request from a voice client of a plurality of geographically dispersed voice clients coupled to a communication network, causing the service request to be transmitted to a registration redirect server associated with a closest set of feature servers coupled to the communication network; and

causing the service request message to be directed to a particular feature server of the closest set of feature servers based on a load balancing routine executed by the registration redirect server.
