Echo with OBI202 using pstn USB dongle
AndyJ:
Just to add to this... I recently purchased an OBiLINE for use with an OBi200, and hear significant echo. I've been through every ACImpedance setting, and tried adjusting the ChannelTXGain and ChannelRXGain, but cannot get rid of it. Phones plugged into the same jack used by the OBiLINE have absolutely no echo. I can hear the echo even if I connect the OBiLINE to an OBi110's phone port (where there should be an exact 600 ohm impedance match), which completely eliminates the PSTN as a factor.
I've opened a support ticket, so I'm hoping there is some solution.
(I also get very frequent DTMF talk-off with the OBiLINE, but that's another issue...)

Very sorry to say that it seems a consistent problem with that model :( After several tickets and VERY HELPFUL but sadly useless Obihai staff support, we decided to go back to our trusted 110 and never looked back. No traces of echos on that one!

Correction. It may be your experience that there is consistent echo, but it is not an intrinsic problem with the device. I have three of these set up in three different locations and never had a bit of echo, even when the gains were set too hot.

I have the same problem . I Changed the impedance and it reduce but didn't stop. Have you had any luck with support?

Which gain(s) did you turn down and what settings did you end up at? These aren't the first reports of echo I've seen... Just got an Obi 200 and would like to know.
