UBR924s work as well as a cheap voice solution, but if you are going to
spend 750 on an 827, consider getting a couple of MC3810s with FXS and
MFT-T1s. I got an outrageously good deal on mine, $850 for the pair and
while there aren't that many deals like that out there, you should be
able to get a couple of them for 1500 at the most. This gives you the
ability to run ATM back-to-back between them and to do VoFR and VoATM in
addition to VoIP. Depending on how much you want to play with voice,
you can load the AVM up with whatever combination of FXS, FXO and E&M
ports that you want. Otherwise, they function like a 2501 with a faster
processor.
