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?<div><br></div><div>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.</div>
<div><br></div><div>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 required.</div><div><br></div><div>All the best,<br><div>

Hi, it seems have problem with physical issue layer 1, first check wiring connection, by the way  you can check with card led (If ISDN  plugs into the port, the LED will not blink, but in red color.) after  dahdi alarm status, and dahdi restart command.<br>

At last should be signalling mode to signalling = bri_cpe_ptmp<br>
Good luck<br>
