Our phone seems to be stuck in the intercom mode.

Programming a Panasonic KX-T7730 phone to share the same line with a cordless phone using a splitter requires specific steps to ensure proper operation. Keep in mind that splitting a phone line may affect the overall call quality and performance, so it's important to follow the instructions carefully. Here's a general guide to help you set it up:

1. Obtain the Necessary Equipment:
   • Panasonic KX-T7730 phone
   • Cordless phone (compatible with the line splitter)
   • Telephone line splitter (designed to split the line to multiple devices)
2. Connect the Splitter:
   • Plug one end of the telephone line from the wall jack into the "Line" or "Input" port on the splitter.
   • Plug the other end of the splitter into the "Line" or "Input" port on the KX-T7730 phone.
   • Plug the cordless phone's base unit into the "Phone" or "Output" port on the splitter.
3. Configure the KX-T7730:
   • Lift the handset of the KX-T7730 phone.
   • Press the "Program" button, followed by the desired extension number (e.g., "101") or the "Intercom" button.
4. Select the Line:
   • Press the "0" or "CO" button on the KX-T7730 phone's keypad to select an available outside line (usually labeled as "CO" lines).
5. Make a Test Call:
   • Place a test call from the cordless phone to ensure that both devices are functioning as expected. Verify that you can make and receive calls from both phones.
6. Adjust Settings (if needed):
   • Depending on your specific requirements and the features of your phone system, you may need to adjust settings such as ringing patterns, call forwarding, and call waiting. Refer to the user manual for your KX-T7730 phone for instructions on adjusting these settings.
7. Testing and Troubleshooting:
   • Test the setup thoroughly by making and receiving calls from both the KX-T7730 phone and the cordless phone.
   • If you encounter any issues with call quality, dropped calls, or interference, consider consulting a professional technician or your phone service provider for assistance.

Try pressing Intercom then 7311 and 7321. You may have to hit the pound key after each one.

When the system is installed, you need to make sure that only the lines equipped are in the access plan (program 400 in a TA series box). When you go to the intercom on a phone and dial "9" you should get an outside line every time. If that works, system and personal speed dials include that access code as part of the number. eg my test number is 914197845522 9+1+10 digits.

In a TA series system, the lines have to appear on the phone. Press PROGRAM and the CO buttons. Are they assigned? If they are, then you probably have a Class Of Service or Electronic Station Lock issue. Both of them would prevent the phone from getting an outside line.

Carl

Get a picture of that and send it to Panasonic! Your phone would be the *ONLY* one that does, since the button has no light.

Now, the AUTO ANS/MUTE button lights up when pressed to put the intercom in the Auto Answer mode under certain conditions. That could be the one you're seeing. It either forces intercom calls into auto answer if it's a ringing call, or into handsfree answerback if it's a voice call. It also indicates a muted microphone on speakerphone calls.

Carl

Make sure the Auto Answer button is not lit on the empty desk phone, then you could use either 40 to answer all calls, or 4+ the extension number to absolutely answer that phone.

You have a couple of answers, depending on which phone system the phone is connected to.

Pres PROGRAM and dial 1. If the display says PREF. OUT then dial 1 and press STORE then PROG. You now have no PREFERENCE so you get the intercom by default. You get it back or change it by PROG 12 for idle line, or 13x (1-8) for a specific line.

If you didn't get anything with those numbers, try PROG 19 STORE. Then the AUTO ANS key will step you through the choices. That's used on TDA TDE and TAW boxes.

Carl

If using the KX-T7730 phone on a Panasonic 308/616/824 system press Program 11 and then AUTO DIAL / STORE . Press Program to exit programming mode.
