I have one phone in a large phone system (NEC SV8100 DT 300 series). When you call this phone with the full number (externally dial), it rings fine. If you dial it internally (using just the extension), the calling phone's display says "voice call" and the extension number, but does not ring on either end.

Assuming that the standard numbering plan was used by your installer (SV8100/SV9100)
To set the system Time:
1. Press Speaker.
2. Dial 728.
3. Dial two digits for the hour (24 hour clock, 13 = 1:00 PM).
4. Dial two digits for the minutes (00~59).
5. Press Speaker to hang up.

I think you have change its internal setting so reset your phone again so its again setup your phone and your problem has been removed like phone ring.

So much of our modern communications is now VOIP, uses the internet to complete your call. Problem is internet gets slow, or there's 10 different places where voip settings can get messed up and you need a certified service tech to track this down. Even having normal landlines may not help if calls your other offices are routed only over VoIP.

I am not sure which country you are in, but in Australia your divert depends on your phone carrier not your model. If your carrier and call plan supports call forward you just dial their set number and follow the prompts to turn on or off.

What model of NEC phone system do you have? Go look in the phone or data room and look at the PBX. You might also be able to press Feature 3 to get some information which would be helpful to a tech. If it is an SV8100 try this:

Here are two methods to turn off background music, one of these should work depending on which Panasonic phone system your phone is connected to.

1) With phone idle, press the 1 key on the dial pad (turns off background music when it is on and turns on background music when it is off).


2) With phone idle, press intercom button then dial *751 on the dial pad followed by 0 on the dial pad to turn off background music(confirmation tone will be heard) and end by lifting handset and replacing in cradle.

Simply press the RED (end call) button. The call will then be sent to voicemail.

You can toggle each individual phone extension as to whether or not it recieves a "voice" call or a "ring-first" call.

At the extension, press "SPEAKER - 60" it will display the mode. Press the * (asterick) key to toggle between the modes. Then press SPEAKER again to set.
