Is it worth it? - QoS VoIP traffic for GW to internet.



  • Hi All,

    I'm using PFSENSE as my internet gateway for comcast business class internet.  I currently use VoIP.ms as my SIP voip provider and would like to find a way to prioritize the traffic.

    My issue here is that others in the house will load up a youtube video and kill my VoIP quality. It's my understanding that QOS is only as good as the two connection points over a dedicated link where ALL traffic is passing.

    I suppose what I'm looking for here is too cap / slow the youtube traffic when I have VoIP traffic on the network.



  • Hey rbblue8,

    I too use voip.ms over IAX2 though. Now I am no expert but my solution was to create a PRIQ queue with VOIP and let everything else fall under the default queue. I then deleted and recreated the voip floating rule to lock down the source and destination with port 4569 (IAX2 udp port) in both direction. So I have 2 rules, 1 VOIP rule for voip.ms server ip to internal asterisk server and 1 VOIP rule asterisk server to voip.ms both using the qVOIP queue. PRIQ is a simple priority queue so it will choke anything lower then the queue that needs the bandwidth, so the VOIP queue with throttle the default in my case. I find my call quality to be great especially with incoming calls. Someone might have a better solution but this is one you could try.



  • Hey,

    Thanks for the response!  :-)

    Do you see a noticeable difference when you make a call while downloading?

    If you cap both your upload and download to just below your providers true limit, I found it sounds as good as if there was no one downloading at all. Just a couple of minor hickups but I was just calling my cell phone and leaving a message to hear the difference. I very rarely saturate my line so for this I did remove my sabnzbd's cap on usenet while downloading to do. So give it a shot, I think you'll be happy with it.
