We are looking to setup a secure SIP lookup directory/exchange where clients upload their VoIP telephone numbers and their corresponding SIP URI address through a website. The primary initial focus is allowing small VOIP providers to peer and exchange calls SIP to SIP if available, as opposed to going VOIP to PSTN and back to VOIP.
