[Asterisk-Users] Static on inside end of conversation

[Health Masters]

We have the same problem lately we thought maybe our upgrade and testing 
of the .13 firmware.. but we are running 20 phones on a  p4 2.6 w/512 4 
PSTN lines on TDM400P and have 3 fat client pc's and 7 pcexpanions ( 
http://ncomputing.com/ ) running to a fat client. We did not have the 
issue on firmware .09 or .12. What firmware are you using?
