Phone calls work out of the box and I have had very few problems. In very rare occasions I have had the modem refuse to work. Rebooting the machine does not solve the problem where the modem refuses to work. I had to power off the mode and then power it back on to fix this problem. This is exceptionally easy thanks to the <strong>Librem5</strong> design.

- There appears to be built in <abbr title="Voice of Internet Protocol">VoIP</abbr> support. I have not tried this but it should be interesting to see it work.

There is also built in encrypted call support. I have not tried this yet.
