Hi -
I had a client recently move their asterisk system (asterisk 1.4.26,
dahdi 2.2.0.1, aex800 w/vpm module) to a new location, a building
that's nearly 150 years old. I was not personally able to go there,
but the person who did the move said the building's demarc room was
scary-- water leaks,

Before using this version, did you have audio clipping issues (this version

Weeks ago, we installed HPEC and got such serious audio clipping issues we

should be taken care of now. However, if you still see ANY sort of
