to my experience the application and the configuration works fine. in 2 out
of 3 cases the speech quality is ok, and hangup works as well. in some
cases it looks like some timeout occurs. in many of the cases the reason is
just a temporary cut of the mobile internet line. this means a forcibly cut
off line is "the normal case". i saw it happening also with collegues,
using android, and some dellmont service, like actionvoip. or would you say
these services are so low quality that it is pointless to adress it?
