    NV6310/NV6355 - rx/tx gain on FXS ports for modem passthrough

      For the few times that credit card/fax machines give trouble using these, what do you do if an outside loop in unavailable? I have read in the past with similar products that reducing the tx and rx gain could help. I just was not sure if this applied to these models with the later software.
