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.
ISP Speed: 3 M Up/Dn
Router: Linksys RV016
WAN1: 10M Full (per ISP Modem)
DHCP Enabled: .150-199 (for Computers)
DHCP Resrved: .101-149 (for VOIP Devices)
Bandwidth Management: Rate Control
All TCP/UDP Traffic~192.168.1.101-149~UP~256/512
All TCP/UDP Traffic~192.168.1.101-149~DN~256/512
(Also used min max of 1024, 1548)
VOIP1~UDP~5060- 5090 (As per VOIP provider)
VOIP2~UDP~16384-16482 (As per VOIP provider)

(only used by me for adjusting configuration remotely)
I have this problem too.
