I have a strange problem with random phones at random times going off hook by themselves and making a long tone until the user picks up the handset and hangs it back up. I have been keeping record of the different phones doing this and they are not tied to a specific card. So, I don't think it is a particular DTIB card going out. I have several different types of phones on the system: 12&24btn Infinite/display and non-display modles plus 30btn LKD display phones. This is an XTS system Eng. Ver3.50.2-3FE3. Any suggestions on troubleshooting this issue would be greatly appreciated. Thanks,

Try a 2 pin line cord and disconnect any unused pairs that are connected to the jack. This has solved the issue for me in many instances of the same problem that you are describing.

Thanks oobie, I will give that a try.

I've seen that many times when a single phone is going bad. Its one condition where non-authorized repair centers are not worth using. If anyone has had better success than I have in this regard, please chime in.

Several phones going bad all at once? That I haven't seen. Is it possible that one phone is phantom dialing to those other phones? What do all the displays show?

I tried changing all the problem phones to 2 conductor pinouts on the line cords. This had no affect on the problem though. I haven't yet verified if there is anything on the display when the off hook squawk condition occurs.

I had one phone that used to randomly phantom dial the operator & other extensions before I changed from a DVXII to an XTS phone cabinet. This is one of the problem extensions now. I did change this person's phone out prior to the cabinet changeover which seemed to resolve the phantom dial problem.

However, knowing that this same extension is one of the ones currently having issues, it is possible that just the port and not specifically the phone itself is actually having a problem. It could be phantom dialing again. I did re-use the same DTIB cards from the old DVX system.

In my experience, I have only seen this condition when phones go bad. Why you have so many is a new one. But if you have two DTIBs and can swap them, you can see if the problem follows or stays at the phones. If it stays at the phones, I would then examine the site for any possibility of EMF or RF type of interference.

I had a bad DTIB cause this kind of problem. Phones would go off hook, call each other, page the whole office and call the operator. It was a lot of fun for awhile.

Thanks MNDAVE and Derrick. I think I will try and get another DTIB card and see if anything improves after replacing my suspect card. I will report on the results. Thanks again.

I'm assuming the phones squawk when you are answering the phone. This is just a thought. Had a STSe squawk when answering the phones. Caller ID ring delay was not set. I set the delay to 5 & squawk was gone. Not sure if this your problem, but it was mine.

This squawk happens at random times to random extensions and it occurs while the handset is onhook. The phone just randomly goes offhook and a Long squawk (Tone) comes from the speakerphone and continues until the user picks up the handset and and hangs it backup up again.
