[A*UG] PRI and line sharing

[Mark Barry]

Most of the time what I have seen from TWT for this type of setup in
sometimes refereed to as an integrated T. They provide a box that terminates
one side to the PRI and the other to the data network. If it is an older
setup, it might have the PRI terminated into a channel bank.
In any case my original comment stills stands, that your TWT provider needs
to make the DIDs hunt across all the PRI lines.

When the calls come in to Asterisk from the PRI card/channel, it will have a
variable (DID) that you can read in your dial plan and then route the call
to an IVR or where ever you want.
