Possible Cause 1: Forced Account Code Entry is active.
What to do: Find out if
Forced Account Code Entry (#307) is assigned to your extension.
If it is, follow the procedure for entering an account code.
■
■
If you can make a call, the problem is solved.
If Forced Account Code Entry is not assigned to your extension, go to Possible
Cause 2.
Possible Cause 2: Dial Mode is set incorrectly.
What to do: Find out if you have touch-tone or rotary service and set the
Dial Mode (#201)
to “Touch-Tone” or “Rotary.”
■
■
If you can make a call, the problem is solved.
If the Dial Mode is already set correctly, go to Possible Cause 3.
Possible Cause 3: Someone may have changed the Outgoing Call Restriction setting.
What to do: If you were able to make a call without any trouble before, find out if someone
changed the
Outgoing Call Restriction (#401) for your extension.
■
If you were able to call on the phone before, and no one changed your Outgoing Call
Restriction (#401) setting, go to Possible Cause 4.
Possible Cause 4: Local phone company is not accurately receiving the dialing signals.
What to do: Isolate the problem. Use the telephone to make calls on different lines. Then,
make calls on different phones using the same line.
■
■
If you cannot make calls from one phone on all lines, follow the procedure for “Other
Problems with Phones,” Possible Cause 2.
If you cannot make calls using different phones, go to Possible Cause 5 on the next
page.
