Abstract
Systems and techniques for providing call server failure protection involve assigning a set of media gateways to each of three or more call servers. Each call server has primary control of the corresponding assigned set of media gateways. A second call server is designated as having secondary control of a first media gateway assigned to a first of the call servers. A third call server is designated as having secondary control of a second media gateway assigned to the first call server. Secondary control is activated in response to a failure of the first call server.
