OK; here's a problem tim. Probably not with 99% of all people, but with my configuration, it IS a problem. So much so, that I would probably only use this clone feature as an OUTGOING LINE ONLY. I would NOT use it to answer calls. Ok, here's the deal.

The most basic of setups; NO PROBLEM. 1 phone in port 1 and a 2nd phone in port 2. Calls out simultaneously on both lines. Works fine. Incoming call; answer either phone and it's fine. Talking on one; incoming call; call waiting beep (I believe) and I can answer with the 2nd phone. ALL GOOD NO PROBLEM.

Advanced Setup: My port (line 1) is my standard line. I have it wired into my house wiring. I have 6 phones currently connected into the house wiring. I have had more, but currently just 6. All normal outgoing and incoming calls work fine. If I add the 2nd phone to port 2; all OUTGOING calls are still fine. I can have a call in progress on port 1, and make a 2nd call on port 2. HOWEVER; if during an incoming call, if I have the 2nd phone connected to port 2 and I try and answer an incoming call on that phone, I get dead air, the distant end continues to ring, and then the GS 502 reboots itself.

Again; OUTGOING is fine; but answering incoming on the 2nd port locks up the adapter. This ONLY happens when I have my house phones all connected to port 1 at the same time. If I only have 1 phone connected to port 1, no problem.

So, it's probably a current issue with the 502. We can't expect that little box to handle the type of line current that ma bell sends down the line. I will experiment to determine if it's a PARTICULAR phone on my house line, or just when it's "MORE THAN SO MANY" phones connected. I'll let you know.

On a side note; I assume that this is a feature that a person could have turned OFF if they wanted to. 1st: Not everyone has a need for it. 2nd: Some people, if they wanted a 2nd actual number/line would prefer that port 2 be used for that INSTEAD of having to have a 2nd adapter. Just an observation. Personally, based on our call usage, I really don't have a need for this feature. But it is definitely something that could be very useful to some people no doubt. Anyway, that's the issue I am having. Something you might want to jot down some place in case other have their adapter wired into their house wires and are using numerous phones. Also, part of my test will be to change around and have the single phone in port 1 and the 6 wired house phones in port 2. I'll let you know. later.... mike.....
