ABSTRACT:
A method, apparatus, and communication network system that allows an endpoint to be simultaneously registered with more than one communications server is described. In one embodiment, the communication network system includes a network, a plurality of communications servers that are coupled to the network, and a plurality of endpoints coupled to the network. Each endpoint is capable of being simultaneously registered with more than one communications server. A communication method for an endpoint involves registering a first logical line of the endpoint with a first communications server, and registering a second logical line of the endpoint with a second communications server. Consequently, flexibility is obtained by allowing an endpoint to choose the registering communications server for each logical line of the endpoint.
