Single-Line Telephone Problems

If more than one single-line telephone cannot dial correctly, even though they are receiving calls, use the steps below to test the touch-tone receivers (TTRs) for a single-line telephone.

1Pick up the handset; then dial *04 and the 2-digit number of the TTR you want to test.

■If you hear a busy tone, the receiver is in use/off hook.

■If you hear a reorder tone, you have misdialed or have reached an invalid TTR. Try again.

■If you hear a dial tone, go to Step 2.

2Dial 123456789*0#.

You should hear a dual-tone multi-frequency (DTMF) signal as you press each button. If the test is successful, you hear a three-beep confirmation tone one to three seconds after you press #.

3Hang up and repeat Steps 1 and 2 for each TTR.

4If this test fails, replace the module containing the faulty TTR.

If all TTRs fail this test, repeat the test, using a different telephone that works. If the tests are successful, replace the original telephone.

If users cannot make outside calls on a touch-tone telephone, check the individual trunk for rotary-dial programming. See System Programming for details.

Call Forwarding Problems

Call Forwarding problems usually occur when someone activates Call Forwarding unintentionally, resulting in a user receiving other users’ calls.
