I've been in the same boat, Matt. I've been on their website, and the Tolly reports seem to give Shoreline a lot of praise. Makes me think Tolly is a partner of some sorts. So, I went to the Tolly site and saw reports from several vendors. Went to the Avaya site, and they were boasting about their Tolly ratings as well. I'm looking at designing a VoIP network, myself, and asked one guy from a different company, and he recommended Shoreline. As the story goes, the problem with VoIP is not so much the equipment, as it is with the network - latency and jitter, etc. So far as shoreline is concerned, at this point, it looks fine.
