Putting a call on hold doesn't introduce anything into the phone line. I have seen other manufacturer's systems drop lines on hold because there isn't enough loop current to maintain the line seizure. I've never seen this occur on any XTS equipment and you do appear to have ruled out the LCOBs. Have you checked the loop current between an active call and a call on hold? Have you tried Derrick's button test yet?

You know unused co lines can be programmed as MOH sources. Is it possible that was done at some point and now the line is live again? If so the system maybe connecting the co as MOH when you put someone on hold, they would get dialtone and then the line times out and starts howling. I bet the caller on hold might be able to dial a number!

went out to the site.swapped out the cpu card, no change. checked the co settings. the co lines were programed for MOH #1, they do not have MOH. change from 1 to 0 and the problem is gone.

MOH ports 1 and 2 are on the MISB card. That card could have tdm errors.

I started to ask if you had an MISB installed, because missing will cause this is if MOH is enabled. I didn't think of it at first because the MISB came standard with all systems for years.

Derrick - good job! I didn't even think about MOH. And ditto on the MISBs. I can't recall that I ever had a system installed without one. I even still have spares because I always ordered packages whenever I needed an expansion KSU. They were basically free at that point.
