Intercom Function Stopped Working

Help! I work in a small office (we have four of these phones) and we greatly rely on the intercom function. About a week or two ago, it just stopped working. Most of the time it simply says "no answer" on the phone "intercoming" but it never rings through. On a rare occasion, it will finally ring through, but you can't answer it. I've tried unplugging and replugging all the phones. I've restored default settings. I've called RCA's customer service. Nothing has worked. Does anyone have any suggestions? My boss wants it fixed yesterday... and I'm all out of ideas. Any help would be appreciated! Thank you.

SOURCE: Intercom

I do not have any information on your specific phone but I'd like to try and help. Typically a multi-line phone set up like this would need a way to intercom between phones. I have not seen one that can utilize the same wires as the phone service but I also have not looked. It would also need each phone to have it's own identification (extension assignment). You only need two wires for each phone line but for intercom there most likely needs to be another pair of wires connecting all the phones together. I hope you have a manual. Look carefully at the section dealing with wiring up the phones to the phone lines. It should mention intercom at some point and what is required. Also, you can have up to 16 phones. Each phone must have a setting to choose a number between 1-16 or maybe 10-25, 100-115. By default these will all be at the same setting and you would not be able to intercom.

You have disable paging service on the phone itself. its under regional/phone settings. better yet, delete all the vertical activation codes and service features to no.

How to use the intercom system

  • Check your telephone to see if it has an intercom feature. Many wireless phones that come with multiple units allow you to temporarily turn one unit into an intercom to contact other units attached to the same wireless phone system. Depending on the model, you can contact all the other phones at once, or a single specific phone, by pushing the intercom button and entering the other mode. To put the phone back into regular mode, all you have to do is switch off the intercom option.

  • Contact your telephone provider. Some telephone service providers allow landline phones to call themselves, which enables the phone to function as an improvised intercom. You would simply pick up the phone, dial and then close the connection. Once the phone is answered elsewhere in the house, you will have established a line to another phone and you can speak normally on it. This has largely been eliminated due to lack of need as technology advances, but it may still be an option with some providers.

  • Purchase and install an intercom system that will work through an existing phone line. Many of these products, some of which are produced by Panasonic, operate as a halfway point between a traditional intercom system and a phone line. The exterior intercom links directly to the phone line, and you can pick up the phone and talk through the intercom unit outside once the system is properly set up

    Intercom / page problem with AT&T phones model 944 and 955

    Do you have DSL on this line? Make sure you have filters on the lines going to the phones or take the line coming out of your DSL modem and split it to the phones.

    Also, try unplugging your fax, computer modem or credit card machine and test the intercom. Sharing one line for several devices can make the intercom unhappy.

    Intercom on one of the office phones has stopped working?

    Press Feature * 0, then press the button you think is the 2nd intercom button. What does it say on the display?

    Chances are that the button got erased. Do you know how to get into system admin programming?

    Be sure you are pressing the correct extension key for the phone you are attempting to call. Just press 'intercom' and the key number (from the right side of the phone marked 1-16).

    PLEASE, PLEASE try and help me...I can't tell you how much this would be appreciated. I have a Panasonic KTS4100 4 line phone (2 corded phones in our office, and one cordless). I have NO IDEA how to use...

    Just in case you missed the manual:

    There are 2 conditions you need to be aware of

    1 No DSL on the line
    2. Set the intercom extension of the second phone

    By default, both have been assigned ext 11. The intercom uses the same frequencies as a DSL line to transmit, so that could be the noise you are hearing.

    Page 23 tells you how to set the intercom extension, and the DSL warning is almost at the bottom of every page from 18-22.

    Phone not working. I left it unpluged all night to reboot. Same proplen. No service in or out. Badse keeps flashing "Welcome Please wait"

    Pls check if the intercom function works. If yes, then the base is simply waiting for the presence of a dialtone on the telephone line. It would be required to check your telephone wire connections. Further, if you have an extension telephone, pls verify that indeed you have dialtone along the same line. In most instances, you may need to contact your phone provider to verify service.

    If no intercom function, it may simply need pairing again or redo the initial install setup.

    Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

    Good luck and kind regards. Thank you for using FixYa.
