Other Problems with Phones

What to do:
If calls could be made without trouble before, find out if someone
changed the Outgoing Call Restriction (#401) for the extension.
If someone changed the Outgoing Call Restriction setting, verify that the
change was an appropriate one.
If no one changed the Outgoing Call Restriction setting, go to Possible
Cause 4.
Possible Cause 4:
Station Lock was used to lock the extension.
What to do:
Use Station Unlock from extension 10 to unlock the extension.
If you can make a call, the problem is solved.
If the extension was not locked, go to Possible Cause 5.
Possible Cause 5:
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 “System Phone Does Not Work,” Possible Cause 2.
If you cannot make calls using different phones, go to Possible Cause 6.
Possible Cause 6:
Too many standard devices are trying to dial simultaneously. (If
the problem is on a system phone, go to Possible Cause 7.)
What to do:
Stay on the line and wait for dial tone, or try to call later.
If you can make a call, you may want to increase the number of touch-tone
receivers by adding 206 (1 receiver), 400 (2 receivers), or 308EC (6
receivers) modules to avoid future problems. Call the hotline (see page
6-1). If you wait 30 seconds and still do not hear a dial tone, go to Possible
Cause 7.
Possible Cause 7:
Local phone company line is faulty.
What to do:
One at a time, unplug each outside line from each 206, 308EC, 400,
and 200 module in the control unit. Then plug each line into a standard telephone
and try to make a call.
If the trouble occurs on the standard phone, try another line cord; if the
trouble persists, report it to your local phone company.
If the trouble does not occur on the standard phone, the trouble is with your
control unit. Call the hotline (see page 6-1).
