Sorry, INT16_MIN again actually. The main point still stands though, I think.

Just to verify, a 16-bit divion of INT16_MIN by -1 results in INT16_MIN
again?
If the issue only occurs in this case, why aren't there checks to see if we
can simplify sdiv in cases where we know that numerator is not INT16_MIN or
the denominator is not -1. For example, we could simplify divides involving
one operand consta...

Bandwidth management and ADSL router
Hi All;
I discover that most of the voice cutting complain are coming from the Internet bandwidth when we are connecting two remote offices togethor via Asterisk or any other IP PBX.
