I am using shorewall as my firewall and traffic shaping platform; however, I'm wondering what more I can do to help mitigate upstream jitter issues. I have a fair amount of bandwidth, but the connection is not stable and enough so that jitter causes VoIP calls to be choppy.
I am already shaping the VoIP traffic and assigning it the highest priority. I am planning to switch from guaranteeing 80% of the bandwidth to a set limit of 1Mb/s which should be more than sufficient.
Is there something more I can do, if so, at which level? The problem with the call quality happens at both ends. If I implement some sort of buffer on my end, that will fix the call choppiness when I attempt to hear others, but what can I do to fix others hearing me?
