New error occured : Getting messages like this "Lost 171 audio packets durin last call. (10.76%)"

Hello, I am having a problem with calls from express talk. Like I said in the title, my call ends automatically ALWAYS after 31 seconds reporting no error message.. I am thinking there is a problem in one of the switches in our office or provider (we are currently on 3 switch system). When I connect through my cell phones wi-fi hotspot and 3G, everything works allright so it´s not bad program config issue. Anyone have any idea what causes this ? Thanks for any reply
