Obi202 Echo Help Please
tpir72:
Right now it is setup OBI is VOIP and Router:
Modem > OBI > Switch > Other Computers/Devices
I did have Modem > Router > Switch > Computers and Devices (including OBI)
Both setups have Echo issues.
I recently tried OBI in the first layout above to keep VOIP ahead of everything else.
I don't fully understand when I used Vonage and Skype..... No Echo....
Regards,
Terry

Has anyone tried this in OBI202 or Google Voice to kill Echo?
How/where do I change this?
VoEAudioProcessing::SetEcStatus

Terry
lhm.:
Try removing OpenDns from all configs as a test. Use 8.8.8.8 (Google) or 4.2.2.6 (Verizon).
Obi recommends not using Open DNS.
"The OBi is Using openDNS & the Google Voice Status Always Says Backing Off
You cannot use openDNS with the OBi. To workaround this issue, please do the following:
• Modify the DNSServer1 parameter value by accessing the OBi's web page.
• Select System Management from the left-side navigation menu
• Select Network Settings
• Locate the parameter called: DNSServer1
• Make DNSServer1 = 4.2.2.2 (This is a free public DNS server)
• Select Submit to save and Reboot the OBi
The OBi should no longer show Backing Off."
ipse:
I'm not an expert, but why would DNS play a role in his echo problem? Once the IP of the server is resolved, the rest is pure IP traffic, DNS is out of the picture.
I'd rather look into QoS and packet processing - I have an Obi110 and religiously configured QoS (MAC based) on ny Tomato router. No echo.

That may work.
Some other possible remedy suggested in the past:
Make this default setting: OBi's Ethernet ports to 100 mb/s full duplex
