Installed and set up PRI today with a Digium TE110P, Line Coding - NI1 - National ISDN 1, Line Framing - ESF, Hunting Sequential/Most Idle, everything went well, worked right from the start, however as we started to make a few calls we noticed an annoying "click" (random but persistent). Spent some time with Digium Tech support, they helped eliminate some echo we had but couldn't get rid of the click. If I called a regular PSTN line, I could hear the noise as could the dialled party, if I dialled an Unlimitel DID only the called party could hear it.
Next we spent about 4 hours on the phone with Hell Canada, eventually got a tester on the line who told us he was seeing errors on our equipment, after another hour of badgering he told us the problem looked like syncronisation and asked if we were syncronised with their main branch clock, or timing device (can't quite remember, been a long day), is there a way to do this? We ran ./zttool and scored an average of 99.9875, the lowest score being 98.99, so I think I can rule out interupts, if anybody could point me in the right direction, it would be greatly appreciated, thanks, Mark.
