Hook Flash is a quick transition of the phone's hook
switch from Off-Hook state to On-Hook state, and back to
Off-Hook state.
This parameter specifies the upper time limit in
milliseconds such that if the hook switch stays at the
intermediate On-Hook state for longer than this time
limit, the OBi device will not recognize the state transition
as a HOOK FLASH event, but instead as an ON HOOK
event followed by an OFF HOOK event
Hook Flash is a quick transition of the phone's hook
switch from Off-Hook state to On-Hook state, and back to
Off-Hook state.
This parameter specifies the lower time limit in
milliseconds such that if the hook switch stays at the
intermediate On-Hook state for less than this time limit,
the OBi device will not recognize the state transition as a
HOOK FLASH event, but consider the hook switch remains
at Off-Hook state throughout the transition (in other
words, the transition is discarded as a glitch if it happens
too quickly)
Minimum time apart between two successive hook flash
events to be recognizable by the device as a double hook
flash event. The unit is in millisconds.
This option is only available in OBi110
Maximum time apart between two successive hook flash
events to be recognizable by the device as a double hook
flash event. The unit is in milliseconds.
This option is only available in OBi110
A short delay in milliseconds before OBi generates a CPC
signal to the PHONE port after the far end has hung up
during a call
OBi device generates CPC (Calling Party Control) Signal by
removing power from the PHONE port for a short period.
This parameter specifies the length of this period in
milliseconds. CPC signal tells the attached phone
equipment that the far end has ended the call
Tip/Ring voltage polarity the line is idle, before a call is
connected, or after one side hangs up. Choices are:
Forward, or Reverse
Tip/Ring voltage polarity when the line is connected on a
call.
Note: By using a different polarity for an Idle and a
Connected line, OBi effectively generates a polarity
reversal signal to the PHONE port, which can be used to
signal the attached phone equipment that the call is
either connected or ended.
