ip stacks are not all that complicated.  they even exist for 8bit µps.

all the code it available to grab and will fit in a reasonable flash.

cf http://www.elphel.com/model313/ for a running on a xilinx fpga for
hardware-speed video compression and a ETRAX100LX 32-bit cpu running
linux for control and networking.

take one of those cpus, a bit of ram and flash, suitable fxo chip(s)
(whether fpga or dsp) and you have enough to do what cisco's ata-186
does.  to be like an ata-188 just add a single-chip 5-way ethernet
switch:  one port connects to the cpu's ethernet port, the other
four are available for external connections.  if you don't have enough
space for four rj45 ports just leave one or two of the swich chip's
ports unconnected.

it should be doable for significantly less than cisco charges.

i agree that this would be a great product for digium, especially as
they can have it support iax and in effect be a mini * server.
