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
*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.
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.
