Some websites you run into show you photos of SIP enabled IP telsets, but the interesting thing, is while it can run on top of an Asterisk for an example; a lot of times they are not. Many open source deployments claims on other sites are heresy, especially if not confirmed. I can say where I live many of these SIP phones go out on the Internet with no box on site. And it’s roaring in and it makes me concerned about small business more vulernable to VOIP than enterprises a decade ago.
