Is there such thing? I believe Obi is tied to Google Voice, Vonage and Nettalk have their own system. I think the best way is to try it and see if it's for you or not. Personally I had telephone service with my cable company which isn't bad at all. My problem started when they started charging me for toll call and Canada, which was suppose to be free. I now have nettalk, which is not as good as the cable phone ( however I am not sure if my cable phone is voip or not). If it is voip..it's a little bit more special than your average voip. I also have been on the receiving end of vonage...but to me, it some leave something to be desire (quality wise).
Hello folks,
I am just curious if anybody here is well versed with VoIP hardware for residential use.
My current phone system is with Cablevision (which is VoIP too). I would like to replace it with cheaper alternative. Ooma and OBi are options but I don't know what exactly is it called as in technical lingo.
I am looking for open hardware (similar to OBi) which can be used with any VoIP provider. I am sure companies like Cisco or Linksys must be making it but I am unable to figure out due to the lack of technical jargon.
Many thanks in advance.
