Obi202: Setting to increase the volume for the caller?

<< < (2/2)

SteveInWA:
It's not intuitive, but "Tx gain" is the amplification of the sound being sent by the OBi (transmitted) to the earpiece of the phone attached to the OBi's telephone interface, and "Rx gain" is the amplification level of the sound being received by the OBi from the phone's microphone.  Most ATAs control the audio gain using these terms.

So:  experiment with the Rx gain, until your helper on the other end of the call says it's loud enough without getting distorted:  not loud enough, use a higher gain number.  Too loud and clipping or distorted sound, back off to a lower number.

I'm having the same issue, what are the preferred numbers you all use for both Rx and Tx Gain (Obi202)?

EDIT:  My settings are not saving anyway, so I am stuck with -5 and -4, which isn't the default.

Further EDIT:  It if I go through the ObiExpert through the web interface as opposed to the local address, the settings save, things sound good at +9/+9.

There are no "preferred" or "correct" values.  It depends on the audio characteristics of the telephone plugged into the device, and your own hearing.
