SIPop! premiered at Fall 2001 VON. SIPop! is the industry's first and only General Availability Interoperability Event, coordinated by pulver.com. The event is designed to help display entire working solutions by the SIP community. While other SIP Interoperability events exist, none offer solutions that are available for sale and installation in a production network.

When it premiered, SIPop! was found by all to be an ideal platform with which to present complete, working solutions to service providers and enterprises looking to supplement or replace their existing PBXs or traditional PSTN solutions. The strength of the event is its unique offering of all possible product and company partnerships in a live working environment right on the show floor. It is possible for a potential buyer to request an on-demand demonstration of multiple vendors' products, and see for themselves a working solution in moments. This unique offering to the potential buyer and to the demonstrating company is what brings such great value to SIPop! participants.
