Hi , I am looking for a voip device that’s really good and great value for money ,I seen few devices with my friends but these guys are not very satisfied with what they have and keep complaining of money they pay it for not using it. Thought I’ll put my question here and look at my options .I basically need a voip service which is free for a start so, I’ll not be paying for not using it as my friends do.
Thanks:-
