Abstract
Methods of establishing an IP link between first and second applications running at respective first and second nodes are provided. The first and second applications are arranged to initiate link establishment over a transport layer by issuing a call to their respective operating system socket Application Programming Interfaces. The methods include at said first node, intercepting a socket call generated by said first application and redirecting the socket call to a SIP-based application resident at said first node; and initiating an IP session with said second node using the SIP protocol.
