[Asterisk-Users] Zaptel/PRI problem

Tan,
My warnings & notices have stopped completely.
I was getting them once every few hours though, instead of
once every few minutes.
However, in the process of trying to resolve issues, we also
rolled back the codebase to 3/5/2004.  This *maybe* a red
herring, but I see several other people on the list
experiencing problems which went away after a 3/5/2004
roll-back.  Now, ours did not (initially) go away.  But the
rollback + interrupts seems to at-least stop the spurious
PRI errors.
