Displaying "phone off hook" message. Any suggestions as to what is causing this? I have done the following: replaced the cord from my DSL box connection to the wall FAX connection, unplugged the power cord from the HP while it was on, pressed * and 6 to reset, return to factory settings, unplugged from the back of HP the connection to the tower--NOTHING WORKS.

A "Line in Use" message generally means that the phone can't get a dial tone. If all of the handsets/phones for that line are on standby or on hook, you need to check the wiring and incoming connection. First, connect a new RJ-11 cord between the phone and the jack. Check if there is a dial tone with the new cord. At least once, I saw a handset cord used in place of the RJ-11 cable. This combination will give this type of issue. If you have a DSL line, check the filter and replace it if it is inside.

For the rest of the wiring trouble-shooting, I like to check the wiring with a basic corded phone. Check if the test phone gets a dial tone at the first jack. If it does, then your first phone has a problem. If there is no dial tone, try plugging in the test phone at another jack on that extension line. If there is a dial tone, that suggests a problem at the first jack or the wiring to that jack. If you do not have a dial tone or there is no second jack, find your service connection. Open the box and look at the connections. If there is an RJ-11 jack, plug in the test phone. If you have a dial tone here, you have a wiring problem. If there is no RJ-11 jack or no dial tone, contact your telephone company. They can test the phone line and determine if the problem is inside or outside.

If the jack could be faulty, remove the cover plate. Look for any loose wires. There are two types of jacks - keystone and screw terminals. To replace a wire in a keystone jack, you will need a punch-down tool available at most hardware stores in the electrical and wiring aisle. Do not strip the wire; just place it in the correct position and push the wire into place with the tool. For the other type of jack, strip a small section of wire and secure it under the screw. See http://www.lanshack.com/wire_phone_jack.aspx to see the terminal connections.

In many places, the phone company technicians will fix an outside problem for free. This includes a DSL filter in the service box. (There are some phone companies that are trying to force system upgrades and will avoid fixing older wiring.) If the problem is inside but not at the jack, you may want a professional to search for the issue. Your phone company technicians will often do this for a fee.

I hope this helps.

(I've had dial tone issues several times. Some were caused by rodents chewing on the copper wires (underground service). Others were due to work crews digging up the wire. A final outage issue had to do with a lightning strike damaging the DSL filter. With a fiber optic connection, we've had two service issues. The first was just after the installation and involved only one jack. That cable had been dropped during the service upgrade. After locating the RJ-11 cable behind the siding and connecting it to the service box port, the problem was solved. The second required a service call - the fiber optic modem card began to fail and couldn't properly translate the signal. The card was replaced solving all of the problems.)

Check your phone line with a) a new cord between the base and the jack and b) a different phone (I prefer an old cordless phone). If you still get a "line in use" message (alternate errors: fast busy signal or no dial tone), use your test phone at a different jack and determine if the issue persists. If you can, find where your phone service comes in and open the box. If you are lucky and have a fairly new service connection, you'll be able to plug your RJ-11 phone line in and check if there is the problem is at the box. If you can't test at this point, you need to contact your phone company to diagnose if the problem is inside or outside.

If the problem is only with the KX-TG65111 phone, try unplugging the base from the phone line and the cord from the wall jack, disconnecting the base AC power cord (from both sides - phone first) and removing the batteries the handset. After a few minutes, plug in phone line, power cord and batteries and test again. If it still fails, then the phone needs service. These cordless phones are not designed for the home user to service. If the phone is under warranty, contact Panasonic. Otherwise, decide if it is worth having the unit serviced or replacing.

If no phone works at this one jack but does work at another jack, you have a wiring problem at the jack or in the wall to the jack. Try opening up the outlet and check for loose or damaged wires. The jack is either wired directly to screw terminals or punch down terminals. For the screws, it's relatively easy to strip the insulation and retighten the connections. For the punch down style, you will need the appropriate tool. (It's available from many hardware stores in the wiring section.) See http://www.lanshack.com/wire_phone_jack.aspx for a diagram of the pins in the jack wiring.

If none of your inside jacks work, look at the exposed wiring and check for any obvious damage. Otherwise, you'll need to find the problem in the walls. You may want a professional to do the job.

If the problem is outside, your phone company will fix the probem for you for free. If the problem is inside, they'll fix the problem for a fee.

If you have a DSL line and a filter on the line, check and replace that if it is part of your inside wiring.

I hope this helps.

(I've gotten a line in use error with a DSL filter problem after a nearby lightning strike. Since my filter is inside the service box, my telephone company handled the repair.)

The router needs to have a modem to run off from, Even DSL provides modems if you do not have a modem then your DSL ISP (Internet Service Provider) did not provide you with one. I would suggest to follow the ethernet cord and see where it plugs into. You will need a modem to use a router.

Hi,
Please find some battery placed into your phone behind or inside. You need to replace those batteries as the drained battery cannot provide needed power for your device operate normally.

Thanks

Hi Jeannie,

Based on your problem I assume that you have DSL. When you get hooked up for DSL they send filters that you are supposed to put between EVERY phone and the jack. (Don't forget phone lines for satellite and alarm systems).

If your dsl drops every time the phone rings, there are usually 2 things that cause this.

1) A bad filter in your house. If a filter is bad or missing it can cause the dsl to drop either when the phone rings or if someone picks up the phone with the bad filter.

2) The other reason could be on your ISP's side. It's called a POTS splitter. You have one of these if you have BOTH phone and DSL. It's what sort of combines the 2 together. There are a number of problems that can occur with a bad pots splitter. i.e. DSL works - phone totally dead, Phone works-dsl - totally dead, disconnects, etc...

I suggest that you hook up the dsl modem by itself. DISCONNECT ALL PHONES IN THE HOUSE. Do NOT have anything connected at all except the dsl modem. No filters, phones, directv, digital cable, or anything else in a phone jack. Then when you are up and surfing, take your cell phone and call your house. Technically it should just ring and ring. Unless you have voice mail in which case it will go to voice mail after so many rings. Anyway, see if when the line is ringing in your cell phone if it is dropping you off. If it DOESN'T, then it's probably one of the filters, jacks, or wiring. If it still disconnects, it's probably the POTS splitter with your ISP.

Good luck and if this helped please help me out and leave feedback!

Thanks!

I had this same problem. I changed the phone cord to a 2 conductor DSL phone cord. Problem solved. Try it. It should work for you.

e4 error code that means it ihas defective base unit. it happened due to a spike in the power lines that may cause this error

Fax machines need an RJ-11 phone cord and are ANALOG

DSL uses RJ-45 and is DIGITAL.

Don't waste your money on a DSL filter, they won't work reliably.

From ethernet of embarq plug it to the Internet port of Linksys. Your PC should be connected to port 1 of Linksys

The cord that plugs into the DSL filter is a phone line and the other end plugs into your DSL modem. Also, every other jack that has a phone or fax or answering machine or caller id box has a DSL filter as well, in between the jack and the device.
