回複：obi110和SPA3102，哪個好？Amazon上obi110的rating要高

I remember that I have answered your question regarding spa3102. obi110 is working with gvoice and that is the selling point. also, it has a second line that you can config to use with another voip servivce. 3102 is very different since it is a voip gateway. there are two ports on the unit and one for your regular phone and one for connect your 3102 to a pstn line.
