Great product and I am testing it as we speak able to setup the extension to work properly in our network and now ready to add voip and pstn converter. Need some advice here, I apologize if these has been asked many times, I did search but boy I am overloaded 1. Sunrocket = anyone able to get this working with SR equipment or some sort of away around it? 2. voip = I saw some tested list on this website, but which one is best bang for the buck? 3. Pstn adapter = which sipura model recommended? I am thinking I need one with 2-4 line coming in. Thanks in advance, Sparky.
