Voice Transmission Problems

works.

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.
1. 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.
I
If you hear a reorder tone, you have misdialed or have reached an invalid TTR. Try again.
I
If you hear a dial tone, go to Step 2.
I
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 #.
3. Hang up and repeat Steps 1 and 2 for each TTR.
4. 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 system programming
for the individual trunk for rotary-dial programming.
