<br>
I've been trying to get my ISDN-10 line up for the past few days, but<br>
its been going up and down. I am using OpenVox D110P card on<br>
asterisk version 1.4.21. It seems to me like a cable problem. I tried<br>
using Ethernet straight cable (12, 45, 36, 78) and also a "straight"<br>
cable where the twisted pairs are on 12, 34, 56 and 78. The problem<br>
remains the same.<br>
