Trying to use ATA 192 with this firmware 11-2-2MPP0101-013 and changing the input and output gain settings on the Regional page to get more or less volume. They do not appear to work. If I change the input and output gain settings, submit them, then there is no change to the delivered volume or the received volume on the connected phone. Tried powering ATA 192 down and up again. The settings on the web page are as I configured, but the delivered volume is unchanged.
Did the same on the earlier model SPA122 (which we are trying to replace with the ATA 192) and the volume is changed.
How do I get the gain settings to work?
