Methods and systems to allow multiple SIP applications on a SIP client enabling it to select specific applications and features on a SIP server

摘要

A method is provided for a SIP client to select a SIP application and a SIP feature associated with the SIP application by sending a message to a remote SIP server that includes the identification of the SIP application and SIP feature. The message may be generated by the SIP client using SIP application configuration information stored on the SIP client. The SIP application configuration information includes information about SIP applications and associated features and where the SIP applications can be located. A further method is provided for a SIP enabled device, for example a SIP client or a SIP server, to be provided with SIP application configuration information by a configuration server. Various SIP enabled devices and a configuration server for implementing the methods are also described herein.
