We have a number of customers out there with SPA-942s and have also found
ourselves having to increase the input gain to 6.

We've not had issues with the background noise, but we have sometimes found
that the input gain introduces echo, even on purely IP-IP routes. It's only
intermittent and not enough to bother the majority of users, but it does
crop up from time to time.

Apart from the config interface, I wonder if there's anything preventing
Linksys from providing other options apart from -6, 0 and 6 ? I think
something like 3 or 4 would probably achieve the desired volume increase
without causing the introduction of echo.

Has anyone tried forcing non-standard figures through a provisioning system?
