Abstract: A resolution of the address of an SIP proxy in an SIP network, with redundant SIP proxy resources, is provided. To establish a connection in an SIP network, an SIP client typically transmits a request to a DNS server system to obtain an address to gain access to SIP proxy resources. The SIP proxy resources are provided in the form of SIP proxy servers which are part of a peer-to-peer group. Messages are exchanged within the peer-to-peer group via a peer-to-peer protocol in order to communicate responsibilities for SIP domains or user-agent addresses. Adjustable responsibilities are defined within group. The address of the SIP proxy server responsible for the request of the SIP client is made available to the DNS server system so the DNS server system can forward the address to the SIP client so as to allow the SIP client to access the relevant Sip proxy server.
