Anyone else having the same problem? Been using internetcalls.com on my trixbox for a while then suddenly 2 days ago things go nuts can dial out with no problems, other party can here me, but i can not hear them. Box is on a DMZ and my sipgate and voipfone accounts work well. Reading the voipbuster fourm lots of people also had problems at the sa,e time with various pieces soft & hardphones, but no comments back from teh company. Anyone worked out what the cause is and what the solution might be?
