I haven't disconnected all of the phones, but I got an extra phone and removed each phone, one at a time. After replacing a phone, I waited until the problem happened again and then replaced another phone. I'm pretty sure that it's not the phones, although I suppose it could be related to the power supply. If that's the case, then perhaps the NUMBER of phones that the unit is driving is an issue. > It may be a problem in the system.

I suppose that if I remove the expansion card and the problem stops occurring, then I can limit it to the card or to the power draw. Of course, this problem sometimes occurs only once a week, so it can take quite a while to determine if the problem has gone away. > I had a 624 experiencing odd problems, swapping and unplugging phones didn't > help.

By the way, 2 of the ports are connected to SLT answering machines, with the TAM setting enabled. (No, this isn't the same system that my TVS75 is connected to.) Come to think of it, I'm not sure that I've unplugged the TAMs in my tests. Other than that the system is pretty vanilla. By the way... One other symptom I've noticed that I forgot to mention... W hen two system phones are conferencing with an outside call and one hangs up, the system sometimes disconnects the call (as if the second extension wasn't off-hook). I don't know if this is related. (It appears to occur mostly in conjuction when I hang up my KX-TD7895.) Todd: Does any of this sound familiar to you? FYI my system is a -0, so I doubt that your -4 upgrade is responsible for this unless you damaged something in the process. My system also has 2 active CO lines and an expansion card. The expansion card has 3 CO lines as well as 8 extensions. I don't have CID. -- Mark _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
