Since an ata can only do compression on one phone line at a time,
consider it to be nothing more than a single line device if bandwidth is
of concern. Also notice the various problems with SIP that crop up from
time to time. It is actually more useful to use IAX and a small PC with
TDM cards than an ATA.

As for the billing, you can track individual users of IAX in the CDR and
can easily use it this way for your billing.
