[pfSense Support] Traffic Shaper - VoIP

[John Cianfarani]

Finally got around to testing the shaper again today with VoIP on snapshot 02-19-06.   Tried several things but I could not make it work.   Setup is as follows: 4mbit/800kb cable modem, nothing else connected but a wrap pfsense and 1 phone. Phone is using SIP to connect to a remote asterisk box in a colo center codec is g711.   Inside: LAN Download: 4000 Outside: WAN Upload: 600 (was a little more conservative with this number) Check prioritize voice, type = asterisk and allotted BW of 256Kbits. Nothing else selected just next to the end.     Tested a fews calls just to the asterisk box (like voice mail) and the voice stutters several times a second.  After a few calls after about 5-8secs it would clear up for maybe 2seconds and then resume stutter.  This is a the same issue I’ve seen all my tests of the traffic shaper in the past. Watching the traffic queue screen during a call shows the qVOIPup and qVOIPDown queues with about 15kb or so each and the drops just keep counting higher.  The qlandef  and qwandef both show small amount of traffic of a few 1-2 kb a sec and no drops.  All other queues show 0 traffic and 0 drops. If I turn off the shaper the voice is perfect again.   If you need any more information just ask.  I can probably even setup a temporary asterisk box if you need to connect to test stuff out.   Thanks John Cianfarani
