No ringing sound for second incoming call

sounds like you have it on hold.

Firstly, you have not indicated which phone system your phones are connected to, e.g. KX-TA824, KX-TDA50 or other, so I'm a little in the dark. That being said, most of the Panasonic Systems only display Caller ID information (CID) to phones that are programmed to "Ring" on the line with the incoming call, and the line button flashes green to show it's ringing... so you must "system program" ringing for the line(s) on each phone. If the CID is not displayed on a particular phone, then that line is likely not programed to ring on that phone (it's light may flash red instead of green). After you "system program" the line to ring, you can still shut off the ringing sound on a phone using the slide switch on the left edge of the phone if you don't want to hear ringing, and this will not interfere with the CID display. Also, on a second note, CID does not display on the first ring coming in from the phone company (TELCO). The CID signal is sent from the TELCO to your system after the first ring has ended, during what would be the silence period that would occur before the second ring, if there was no CID. It is for that reason that most knowledgeable installers program lines with a five second delayed ring; in this way, you don't know the call has arrived until after enough time has passed for your system to receive the CID signal... this is why it seems the CID appears instantly, with an incoming call. Check out the line programming for each line and set it to ring with a 5 second delay. If you don't set up a delay, your phones will ring and if you answer the call immediately, its likely it won't allow the system to receive CID, so no CID will be displayed for that call.

First assing the flexible ringing day, night, lunch in programs 408 to 410, the assign the delay ringing for the extensions you want in 411 to 413.

PRESS PROGRAM #* STORE

A couple of ways, the easiest is to dial *41103 on the intercom. *40 may also work, but it picks up any ringing outside line.

You have to do 2 things: Make it ring and turn on Line Preference-Incoming Ringing line. The first is done from SYSTEM programming in programs 408/409/410 for DAY/NIGHT/LUNCH. The second is defaulted to Ringing so if the phone rings, it's supposed to work. If you've changed it, then from your idle phone you press PROGRAM and dial 22 STORE. (21 is no preference and 23 plus a number is a specific line).

There are 2 things that would prevent you from being able to answer a ringing phone by picking up the handset. Your phone has to be ringing, and you need to set preferred line ringing on incoming calls.

The second part is easy. Press PROGRAM 99 and dial 22 STORE on your phone. Now when a call rings on your phone you can pick it up. If you can't, then your phone is not ringing.

Ringing is set in system programming.

Examples
Receptionist Call Routing. If you want calls to be answered by the receptionist first, set the lines at the receptionist’s extension to Immediate Ring and the lines at the users’ extensions to No Ring. (This is the factory setting)
Receptionist Backup. If you want all calls on a line to ring directly at users’ extensions -with the receptionist providing backup -set the line at the users’ extensions to Immediate Ring. Then set the line (or lines) at the receptionist’s extension to Delayed Ring. An incoming call that is not answered by a user within 20 seconds will also ring at the receptionist’s extension.
Programming
To change the way outside lines or pools ring at an extension:

1. Press [ Feature ] [ 0 ] [ 0 ] [ System Program ] [ System Program ] [ Central Tel Program ].
2. Enter the number of the extension to be programmed for Line Ringing. The green lights next to the line or pool buttons on the phone show the current Line Ringing settings for all lines assigned to the extension. (If a line is not assigned to a button, the green light next to the button is off.) The following ringing options can be shown by the green light next to the line button.
   • Immediate Ring - on steady
   • Delayed Ring - flashes slowly
   • No Ring - flutters quickly
3. To change Line Ringing for any line, press the line or pool button until the button light shows the correct setting (the setting for the currently selected line or pool also appears on the display).
4. Continue programming or exit programming mode.

Somewhere you should have a programming and operating manual for your phone system. Typically in a Panasonic you turn on CALL WAITING for both Intercom and Outside lines via a code you dial at each phone on the intercom (7311# 7321# for a TA).

This is assuming that the lines are already programmed to ring at the phone.
