VOIP with TOS=5 on inbound traffic
-
I trying to work out some occasional choppy inbound audio with voip in an asterisk system. My network is 2 vlans. One for data one for voice. The one and only switch in the network, a swr224g4p, seems to be doing a good job at prioritizing voip traffic out to the router which is currently a ddwrt linksys. I have pfsense 2.0 beta livecd on a old pc as a test to replace the linksys with pfsense. I needed 2.0 to have traffic shaping functionally for multiple vlans.
I am now questioning my approach. The ISP is the SIP provider. My location is on a point to point T1 to them with only 2 hops to the PSTN interconnect. They are telling me that they mark all voip traffic coming to me with TOS=5. How does this effect the traffic shaper?
Should I be taking a different approach. All of my pfsense use thus far is for multi-wan. No real traffic shaper experience. Everything I 've seen says I don't want TOS set. But does that apply with the end to end control of the T1? -
It won't matter in this case. ToS is useful for prioritizing traffic before putting it onto a slower link. It is not very likely that the T1 is actually faster than your LAN setup, so I can't see this making any difference whatsoever.
