Do you need 216 fax-lines????????

>From brief scan on the net:
One TDM2400 with six FXS modules costs about 1700 euro's. You need nine
(9*24=216) For hosting the TDM's, you'll probably need 5 machines,
costing ????

One Rhino channelbank with 24 lines cost 2700 euro's. You need nine
(9*24=216) To interface to the rhino's you'll need 9 * T1 lines.
TE411 are about 1900 Euro's

With channelbanks, you might be spending a little bit more money,
but you'll probably only need one ot two machines, instead of of pile.

But why do you really need 216 POTS-lines?
With channelbanks and T1 lines, you'll be spending about 130 euro's per
line. You can have nice desktops phones for less.
Why not one or two channelbanks and 200 new iax-phones?


My 0,02 euro's
