Most devices you will be using will be in some multiple of 24 as that is
the number of channels in a T1. An Adit 600 will allow you up to 48
channels as it is capable of handling 2 T1s on the back and 6 x 8port
cards. So your 100 phones is just 3 Adit 600s, 2 of which are fully
deployed and the 3rd only need have a single 8 port card. Then you need
at least a TE4XXP card and either a T100P or a second TE4XXP card to get
the channels out to the ADITs.

While there is no codec, there is echo canceling and there is servicing
the cards in a timely manner. So you need a pretty decent machine so it
can handle the timing, but it won't be slammed.
