have xo reconfig to 24 loop start lines each channel to have its own number. config each channel to be loopstart same as reg phoneline
What xo is sending requires a pbx or key system to translate the incoming 4 digits to route to a ext that has the the same digits.or is translated
as for the t-1 siganal it can be what ever, d4 esf
just has long as the channel bank matchs xo
do not put lines in a hunt group, then these lines
should act just like reg pots lines. Or buy a phone system that can have t-1 & analog exts then when a call came in, no matter what channel it comes in on will be routed to the modem that has that did #
Hope this helps
