Line CPC/Disconnect Clear
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 recall 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 till it stops the ringbacks.
Fax Detection
If fax calls are not directed properly 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, then set this value to
detect 2 tones.
This parameter controls when the system assumes a call on a telephone line
has been cleared from the network, by detecting a disconnection of the
telephone line. It is set to a default value based on Location. Some
telephone companies use a specific timed disconnect signal (K-Clear) to
indicate when a call has been released. In other cases it is set to a value to
release the call if the line is no longer connected to the network.
