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.

See attached brief for greater summary. Please outline your approach (and why) and experience with open source SIPS software and security.
