Any type of circuit available as an analog line is also available
over a T1. It just minimizes the amount of copper required to deliver
service.
You must look at you original order from your telephone company to
determine the type of circuits they are delivering. They may be POTS
1FB in which case there are no digitis. They may be E&M with none. Or
they may be DID which would be sending digits. Although only the
order would identify the exact number of digits. If they are DID then
you were probably assignen at least one block of 20 numbers to be
delivered on the circuit.
Of course then you need to know how many trunks/circuits you have
active on the T1. For outgoing calls you control which ones to use
for any given call. for incoming they may be divided into multiple
trunk groups with different numbers coming in on different channels.
If they are non DID circuits then they should hit the s exten in
whatever context you have defined for them in zapata.conf on an
incoming call.
Good luck

You can use a normal T1. I have one between an Asterisk box and a
Vodavi switch.
I use 10 channels between them with E&M signalling. Zaptel.conf:
loadzone = us
defaultzone = us
span=1,1,0,esf,b8zs
#bchan=1-10 # set this to 1-15,17-31 for E1
#dchan=24 # set this to 16 for E1
e&m=1-10
#fxsgs=1-10
Then Zapata.conf has:
immediate=no
overlapdial=yes
switchtype=national
signalling=em_w
emdigitwait=1000
channel=>1-10
You have to be careful of timing and such, because basically its
really
no fancier then a set of lines that happen to be on a T1. It opens
and
line and literally sends 4 DTMF codes to the server to tell it
where its
calling. For all intents and purposes it could be a bundle of 10
normal
phone lines.
It is our only site using this method because they wanted a fortune
for
a PRI card. Our Avaya and Nortel PBXs all talk to their Asterisk PBXs
using PRI, MUCH easier. The basic T1 signalling and EM Wink is truly
horrid to work with when the PBX is as dumb as a box of rocks like our
Vodavi system.

Are they configured for inbound calls? If so how?
Usually the telco sends the last 4 digits of the called
phone number
down the line.
Uhm...., don't you need PRI signalling for that?
