For what it's worth, my VoIP service broke when I upgraded to 1.234.
If that sounds like your problem, then it's not just 1.3b14.
I agree with you. It sounds like a similar or even the same problem. I also had the problem that the other person on the line could not hear me when I initiated the call. But my phones did not ring when someone called me.
I hat a look into the change log to see what's common between 1.234 ans 1.3b14 and in my opinion it ist the "nat source port randomisation"
and the updated of Dnsmasq to 2.45
. May be the problem is related to that.
