[GTALUG] Softphone on Linux/Windows?

I finally ported my old home phone to VoIP.ms, and installed their softphone on my cell phone.  FYI,     - VoIP.ms does business in US$.     - They bill in 6-second increment (0.1min), so 30sec call is 0.5min. Now, I tried 2 other softphones on Linux:     - ZoiPer Communicator -- binary     - Linphone -- appimage They are okay  I haven't used them heavily to give a meaning feedback, though. Have you used other Softphone on Linux (or Windows), that you liked? --
