color=#0000ff size=2>so you think this problem is asterisk and not a internet
problem? My customers also complain alot about IAX2 connection to teliax
which seemed to work better in older * versions. I have tried everything

<DIV dir=ltr><FONT face=Arial size=2>This is definitely something that changed
in the 1.07 to 1.24 upgrade. We have a pair of identical 1.07 servers

<DIV dir=ltr>I might try recompiling with the old jitterbuffer to see if it
