Clicking On Lines 2

I have an issue where we are experiencing a clicking sound on the phones. Im still a newbie at this so please bear with me. Its almost like the sound when someone goes off hook. But it happens every 30 seconds or so. I have ruled out telco by some testing I have done and I have swapped out my combo card for a known good one. The problem is only there during external calls. Extension to extension calls are fine. Could this be some sort of impedance setting I have to adjust or something like that? The problem was more severe with the old combo card, but once I swapped it out it became better but definitely still there. Any help or ideas are greatly appreciated. Thanks in advance.
 
test the lines directly with a test set and see if you still get the clicking sound, and yes run the impedance test on all analog lines.
 
also check the cabling from the dmarc to the phone system
 
We had a very similar problem recently and it was the control unit. something was wrong in the backplane.

I checked the telco side of things with my test set and there was no clicking. I also plugged in a cable from analog port 7 to a line port and simulated a call therefore taking the telco completely out of the equation and still had the problem.
 
The most common cause of this is the RJ31X jack used by the alarm company for line seizure. Most alarm systems will check about every thirty seconds to verify the analog line is active. It does this by a very brief off hook action. I would verify the number used by the alarm system and consider a dedicated line.

If you verified through SSA that you were testing with the "dial tone" from port 7 and not one of the real telco lines, and your test call did not leave the system on a telco line, you have a hardware issue. It's either the combo card or the control unit.

Run the test again, with ALL outside lines disconnected from the system, and just your loop around connected, calling an internal extension.
 
I just had this very same issue with 2 different ATM4V2 cards on DS8 modules at two different locations. Swapping the daughter board (ATMV2) cleared the problem. These were both new systems, ordered a day apart, installed in two different cities. The problem appeared after about two days in service. The serial numbers were very close, and Avaya is replacing them for me. Not sure if the combo cards use the same daughter board or not, but in my case, it appears to be a bad batch.
 
op when you swapped out the combo cards with known good ones, how did you verify they were known to be good? are these replacement combo cards new?
 
Here is what we found from Avaya-

"We just got confirmation from Avaya backbone that they are working on this problem. they do not have anything official out yet, but have told us to make sure we are, for the time being, installing all trunk modules (combos and ATM4’s) in slots 3 & 4 on new systems. This seems to alleviate the issue. Any old ones that you encounter, of our recently installed customers, please contact support and they will arrange for this to be fixed by Avaya, but as of this email, please do your due diligence to put the cards in the proper slots to avoid any issue in the first place. And please test and make sure they are working.

More to follow when Avaya comes out with an official bulletin."

We are having the same issue. The only common denominator we had was the same version of IPO & the same provider. In this case Charter Comm. We are going to try this Andhee & see how this works.
