I want to reserve the proper amount of bandwith on my broadband connection when making a VoIP phone call.
So, my QOS Policy is "On when phone in use", QOS QDisc is "TBF", and Maximum Uplink Speed is ??
I'm using G711u as my preferred codec (the most demanding byte count wise, I think).
I need to reserve 64 Kbps, up and down, so that's 128 Kbps. So if my average uplink speed (as measured at a site like speedtest.net) is 950 Kbps, then the value for the Maximum Uplink Speed would be (950 - 128) = 822 Kbps, right? If my measured, averaged speed is 1367 Kbps then my Maximum Uplink Speed would be (1367 - 128) = 1239 Kbps, right?
I think I might be missing something because other posts I've read sometimes advise a value like 10-20% of the average uplink speed. I'm confused as to why it would ever be a percentage because is not the max byte count always known when using a particular codec like G711u?
What am I missing to properly configure my SPA2102 for a particular codec and the known performance of my WAN connection?
