Hi,

I recently tried to install a phone in a vacant jack and now all inbound calls are routed to this phone. I tired different phones and with the same result. There are 2 Jacks that I have the problem with all others are behaving normally. When I unplug the phone in the new jack then the inbound calls are directed to the correct phone.

If I plug in both phones two both of the 2 mutant Jacks they both ring for all inbound calls.

Any Suggestions?

You made the assumption that an empty jack is programmed and ready for use, without even looking into the programming....

Somehow, all inbound calls are pointed to whatever are assigned to the ports to which the jacks are cross connected, and when you plugged in the phones, the calls started ringing. (There is either a vacancy/no answer or OOS redirection occuring).

Best thing to do is trace the cables back to find the ports your phantom cables cross connect to, then research the ports - if you are really interested in trying to find out the "why" - personally, I would just leave the programming as it is, but lift the jumpers off the ports and tag them so nobody tries to cross connect them ever again.

As for your phones, program two new phones on open ports and re-terminate the jumpers.

Thanks for your reply.

What is a Jumper? And which wires should I be looking at? I have three boxes One large gray box one with Norstar written on it, one gray box with flash on the cover and one "box" no cover with alot of wires coming into it? It has 5 rows of wires. 3 with labells T R and then 101 T R 102 T R 103 etc

The last two rows are blue with hand written numbers from 1 -17.

I know this is probably way out of my league for comprehension but I thought I would try.

I found another Jack which makes three all in a row along the same wall but the forth jack on the wall works correctly. When I plug in this phone it says there is a message waiting for me. But there is no message for that assigned extension. The installation was when completed for all the phones when first installed.

Thanks for your help.

No worries. This site is about sharing information. :)

All phone system installations (regardless of the type) follow standards for wiring, although the convention may differ from manufacturer to manufacturer. For example, some phones use a single twisted pair, some use two pairs, etc. One lead of each pair is called the Tip, the other is called the Ring. These names come from the early days of telephony when switchboard operators used long leads with plugs to patch calls through - the plugs had a tip and a ring; the tip made contact to a lead inside of a jack when insereted, while the ring made contact to the outside of the jack - the tip is the positive lead, the ring is the negative. Hence, the lables T and R. The numbers will line up to either the cables going out to the desks, or the ports, without seeing it I can't really say... sorry.

Cables (often 25 pair, and refered to as 'tails') are used to connect a phone system's line cards (on which phones are programmed) to punch blocks. These blocks make up the main distribution frame, or 'mdf.' Likewise, cables that terminate to desk areas are also terminated on separate punch blocks. The stranded wire used to connect the mdf to the floor cables are called 'jumpers.'


If you are checking the messages and there are none, try leaving a message for the extension and then check the mailbox - this should force the message waiting indicator to clear.

You might want to just try some simple checks on your phones. Plug the phone into that working jack and rur FEATURE * 0 and press the intercom button. This should display the phones extension in the display. Do this for each jack to get all the extensions.

Once you have the extensions you can at least tell a service provider what you would like the phones to look like, eg. ext 221 or ext 225. 221 may have all ringing incoming lines and 225 might be just outbound.

In the norstar if the set relocation feature is not turned on the ports start at 101 on 221 ( assuming you have 3 digit extensions ) so if you count up you will know what port the phone is on. This would be found as Calvin stated on the cross connect field. The field from your blue/grey box marked norstar should have two amphenols (the 25 pair cable sometimes call tails) one for the outside phone lines and one for the phone extensions. This should be labelled to say TRK's or STN's and may have the port numbers writen down depending on the company who installed.

You can find the ports associated with the extensions you got from doing Feature * 0 and the "jumpers" that go to the house wiring field (jacks). These should be labelled with the jack numbers, if the jacks are not numbered you have no double check for accuracy.

You can now swing the jumpers from jack to jack to move set programming where you want it.

Depending on the size of your system you may have more than just two Amphenols. A norstar 0x32 would have 3. One for lines, two for extensions.

This is probably to much info but you can go and look at your system and see what is relevant and what isn't.
