I replaced an old router with a Linksys RV016 at a small office comprising about 15 computers and 15 VOIP Phones (using G729a requiring ~80kbps). I am hearing complaints about the following
1) Incoming VOIP Quality is bad, Outgoing is fine.
2) Downloads to computers are slower than before.
I am a bit new to VOIP but have some solid networking experience. However I am concerned I do not fully understand the bandwidth management of this device and I think the Linksys documentation is a little light.
Should I be using priority instead of rate control?
Are the MIN/MAX rate control figures shared among the IP addresses or are they applied to each? I have adjusted these rates up and down without any improvement (although I haven't been back to test myself).
Below are the settings for the router. If anyone has any suggestions I would appreciate the input.
