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.
Pick up the handset; then dial

you want to test.
Dial
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 #.
Hang up and repeat Steps 1 and 2 for each TTR.

If 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.
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.
