Hello, i came here to ask if anyone had tried any voip providers meant to be run primarily as a softphone. I plan to use either 3G/4G or wifi with a laptop running ubuntu to make and receive calls. I don't care very much about features, except caller id, which i assume is pretty much standard. I am looking for the cheapest available plan that has loosely limited or unlimited call length and no ads. (i don't see myself talking for more then 30 minutes at the most) And of course the app should run natively in ubuntu.
Has anyone had time to try some of these? Thanks in advance for any input.
