Callers are having difficulty hearing me although I hear them fine. Are there any adjustments I can make in advanced settings that would boost the upload quality or speed so they can understand what I'm saying?
I am using Google voice with a 202 and have plenty of bandwidth on speed tests.
Do you mean that they are hearing you (audio is indeed reaching their end), but the volume is too low, or do you mean that your voice is not reaching their end (no sound)?
If you mean the former, and you have not messed with the default settings already, then it's caused by a poor quality telephone plugged into the OBi.
You will need a helper, with a phone number you can call, who can be your "audio meter'.
You can increase the volume received by the OBi from your telephone's microphone. You need to use the OBiTALK web portal, click on your device, then get into expert configuration mode. Go to Physical Interfaces-->PHONE1, and find the
ChannelRxGain parameter. Uncheck BOTH boxes to the right of its value. Write down the default value, so you can return to it, if you get too far off. Increase the number, a few dB at a time, until your called party can hear your voice with no distortion -- if it distorts, lower the dB number. Note that the default value is a negative number, so, if it starts at -4, then change it to -2, for example, and see if that helps. If not, change it to 0, then 2, then 4, etc. You must scroll down to the bottom of the page and click Submit to make the change, and wait a few minutes for your device to reboot.
Note that we are adjusting the receive gain. That may sound backwards, but it means, the level of amplification that the OBi adds to the sound it is receiving from your telephone's microphone.
