[asterisk-users] Big practical systems

[Joel Maslak]

I believe this looks like a standard channel bank.  Asterisk generates all audio.  Ring and hook status are sent out of band.  Dial tones are in-band.  Ringback, busy, congestion are in-band audio.  I would think a standard T1 card would be fine.

That said, I would verify this with the LEC.
