Abstract
A method and apparatus are provided for processing a contact with a client within a contact distributor. The method includes the steps of providing a primary SIP back-to-back user agent and an associated secondary SIP back-to-back user agent for each resource of a plurality of resources of the contact distributor and setting up a communication connection between the client and a resource of the plurality of resources through the provided primary back-to-back user agent of the resource. The method further includes the steps of an availability server monitoring the communication connection between the client and the resource, the availability server detecting a failure of the primary back-to-back user agent and the availability server transferring the connection from the primary back-to-back user agent to the associated secondary back-to-back user agent of the resource when the primary back-to-back user agent fails.
