I have a TA824 set up with several incoming CO lines and several PT extensions. The system is programmed so that certain CO lines ring to certain extensions, and some extensions never ring except for transfers and intercom calls. That part works fine. If I unplug the PT phone and plug in an SLT or fax into any extension jack - even the ones programmed to never ring - the SLT rings every time a call comes in on any CO line. Needless to say, this doesn;t work very well with the fax. If I plug an SLT in parallel with a PT phone, the PT phone does what it should, and the SLT never rings. I am confused. Any help out there?

I am a bit rusty on this, but I assume that the 824 handles this similarly to other Panasonic systems. What appears to be the case is that as long as a PT phone is conected in parallel, the system can "see" it. It then assumes that the existing PT programming should remain intact.

If you connect just a standard analog device, the system doesn't know what's there (standard analog or "single-line" phones and devices have no intelligence to tell the system they are there). The system's basic characteristics are to revert to standard port programming defaults. I am sure that there are ways to overcome this limitation.

Doc Boy, you will be better served when one of the Panasonic moderators chimes in, but before then, you need to fill out a complete profile. It's just a common courtesy thing that we ask of our members.

I've not run into that problem before (but after thinking about it not sure Ive ever tried). My first thought is if you are using auto answer (allowing intercom calls)000 and have the ring switch on the phone turned off instead of turning off the ringing through programming.
Just my 2c worth.

"and some extensions never ring except for transfers and intercom calls."
How did you tell these extensions not to ring?
I think Phone_girl_NE may have hit on something.
You need to disable ringing for those extensions in fields 408, 409 and 410
