One of the things that has made ATG's VoIP / SIP service successful is the equipment used at the edge of the network at each customer's site. About 2 years ago we started to look around for a partner with the right equipment and technology to provide us all the controls we needed. We looked at the usual providers: Adtran, Cisco and etc. However, we found Edgewater, a manufacturer in Santa Clara, CA, that had a product line with a suite of features we could use as our platform.
