[asterisk-users] Connecting Asterisk and BT Versatility PBX via NT BRI port

Does the BT Versatility system you are trying to connect require a voltage
on the line, which it would normally get from the BT connection?

Some BRI equipment does, and some does not, and it may be the Panasonic
system you refer to is happy without the voltage, while, perhaps, the BT
Versatility needs it.

If you find out that it does need the voltage, I do not think the OpenVox
card you mentioned will supply it, but I can point you to a solution if

All the best,
