I have installed a "temporary" CTX system in a building that is being expanded. Users are having a hard time hearing on calls due to the background construction noise, even with handset volume at max.

I was wondering if there is anywhere to adjust the trunk line audio level in system programming? I looked a bit, don't see anything.

Or, if there are any other tweaks I could do to get a bit more ovlume for them?

Thanks!
