Got a client that called about their system doing something very strange. Checked all cabling and connections, had AT&T verify their lines, and still no results. :confused: While on the phone in a conversation, the system appears to mute the call totally (Both sides - Caller and Receiver) this happens for 4 to 5 seconds, then all of a sudden the caller is back and both parties hear each other. I've seen where calls are dropped, but MUTED??? Has anyone got any ideas? It is a KX-TA824 with 7 extentions using KX-T7731 phones. Thanks in advance

I've seen on the 624 where a short on the data pair of any station will knock all 8 ports on the card out. If it is a high-resistance short, it would be just enough to cause an overload that quickly resets within a few seconds. In the cases where I've seen this, the culprit has been when stainless steel wall phone jacks were mounted on a metal ring. The clearance was just barely enough to short the yellow and black terminals.
If possible, I'd isolate this by disconnecting any and all wall-mounted phones AT THE KSU for a while and see if the problem clears up. If so, then a simple process of elimination should have you straight in no time.

Kirk, there is a software patch for that or just upgrade it to the latest version. The patch was released around June of 08 as I recall. You can download it from the BTS site. -------------------------------- MrG

Thanks for you replies!
First I must say that we did not install any of the cabling, and that the system was bought by the customer as a refurbished unit. It also has been installed for over 7 months now. This problem only started 3 months ago. So the system operated fine for 4 months.
They state it has gotten worse over time, and is particularly on one extension, but has happened on other extensions, and it doesn't matter what line they are on.
I believe ED is on to something, as this was my main concern after visiting the site 3 months ago, when they first told me about this problem. (I will take pictures tomorrow and post them here for you to see)
During the first trouble call, they told me it was dropping the calls, not muting them, and after a 3 hour visit checking connections, connectors and cross-connects, we could never get it to do it.
So tomorrow, we are going to start by checking, verifying and testing all the cabling to each phone. They are stating that it happens 3 or 4 times a day now, so maybe we can get it to happen while we are there to narrow down the problem. I think Ed has a good idea by isolating each phone. By the way Ed, they only have 1 wall-mounted phone and I do not think it is on a Metal plate. But I will use your idea by disconnecting all the phones, and then reconnecting them one at a time.

YEs, Yes, Yes I have the same problem for the last few months. A 4-5 second silience on both ends with the remote party hearing like a short DTMF tone or screech. My end will hear silence with and increase in back ground volume like someone picks up an another phone on an old POTS line system, if that makes sense. I thought it was my VOIP lines and had replaced modems and adaptor boxs with no fix. Found out it also happens on my POTS line! Had a previous KXTA-624 with no issues. If it is a firmware fix, what is the latest version for KXTA-824 as I have Y911AG070731(M)3.0.3. If there is an upgrade can I get it from someplace else other than BTsupport as I don;t have a login? Thanks for this post as I have been trying to solve this for a while!

I see there is a patch on the Panasonic dealer site. I can send it to anyone that can not get on the site.

Thanks a million Phone Girl! The patch worked like a charm and fixed all my drop out issues. To bad that this issue is not widely known out on the web! I went from a 3.0.3 to 3.0.3I firmware to all those that may have issues like mine.
