Line CPC/Disconnect Clear
If calls are accidentally disconnected in mid conversation, it usually
indicates a problem with the telephone line. TalkSwitch is always looking
for a hang-up signal, called a CPC or Disconnect Clear signal, from the phone
company. If the line has power fluctuations or if the line card at the central
office is defective, CPC signals in the 250 ms range might come down the
line and cause TalkSwitch to hang up. Try increasing this value to correct
the problem.

Ringback Control
If an extension seems to ring back as if a caller was on hold, but when
answered, no one is there, it could indicate a debounce problem with the
phone hook switch. When someone at the extension hangs up, the handset
bounces slightly to cause a flash signal that can be seen by TalkSwitch
before the hang-up. As a result, TalkSwitch puts the line on hold. To help
with this problem, increase this value until it stops ringing back.

Fax Detection
If fax calls are not directed to the fax machine, you may need to set this
option to Detect 1 tone. If it is set to Detect 1 tone and people complain they
have accidentally been routed to the fax machine, set this value to
Detect 2 tones.
