I use the ASAP TF555 switch (roughly $120) to feed voice telephones,
an answering machine, and two Unix nodes all off the single relatively
expensive foreign exchange phone line I have between Scotts Valley and
San Jose.  My UUCP partners just have to add a few digits and commas
after the phone number in their dialing scripts.  It works great and
saves me a fortune.  

The only caveat.  When the DTMF gets faster than 60 ms., the ASAP
starts dropping digits. To counter this with my speedy UUCP partners,I
just make sure they add more digits = 555-1234,,888,888,888. At 70 ms.,
the switching would be reliable with simply 555-1234,,88,88, for
example.
