I am using a server with asterisk and I am trying to prioritize voip
traffick -- I am a newbie at this traffic shaping, so please bear with
me. I used the script below and what happens is thatall traffic in
the bulk class stops after a couple of minutes. Also, should I
include the ports for rtp in the filter statements with the ports 5061
and 4569? Note I have a fairly big pipe -- supposed to be able to do
the full 100mb out.
Here is the script.
#!/bin/sh
