T.38 support was the primary reason for choosing that model. Before the
SPA-112, we used SPA-2102 which had the major disadvantage of being a
router. It meant we had to log in to the box to enable provisioning on
the WAN interface (and just hope that no one plugged a cable into the
LAN).

The SPA-112 is a much better solution.

So far only one bug found: Sudden 90% fax call failure rate in one
specific setup with 4 ATAs, whereas all the ATAs used by other customers
continued to work fine. Problem solved with firmware 1.3.1.
