Send Hook Flash Signal to PSTN
Device does not act on hook flash events detected on the
PHONE port. It either ignores hook flash events OR
regenerates similar hook flash events on the PSTN line if
the phone user is currently in a call using the PSTN line
service when the hook flash event happens. This option
may be useful in cases where the user has traditional call-
waiting or 3-way calling services on his PSTN line service;
hence he can control those PSTN supplementary services
using hook flash signals. However, the OBi in this case
would automatically disables its own call-waiting function
on the PHONE port, and the user would have no means to
tell OBi to make 3-way calls.
Note that an alternative way to let OBi generate a hook
flash signal to the PSTN line is to use a double hook flash
event by hook flashing twice within 700 ms. See the
description of the parameter EnableDoubleHookFlash in
this table. With this enabled, you can still let the device
handle normal hook flash event locally and preserve the
call-waiting and 3-way calling functionalities.
This option is only available in OBi110
CallerIDEnable Enable Caller ID Signal generation. This option can be set
to Yes even if the attached phone is not capable of
displaying Caller ID. There is no harm in sending Caller ID
signal while the phone is in the on hook state. Yes
CallWaitingCallerIDEnable Enable Call Waiting Caller ID (CWCID) Signal generation.
CWCID signal is sent to the phone when it is in the off
hook state. It starts with a handshake between the OBi
device and the attached phone, by exchanging audible
short tones. OBi will proceed with the transmission of the
remaining Caller ID signal only if the handshake succeeds
(with a phone is capable of displaying CWCID). In that
case the phone mutes the handset earpiece until the
CWCID signal is complete. Some users however may still
find the audible handshake tones objectionable,
especially if their phones do not support CWCID. We
recommend to those users to set this option to No, if they
do not want CWCID feature, or do not have phones that
are capable of displaying CWCID. Yes
MWIEnable Enable MWI Signal (stutter dial tone) generation. If
enabled, any SP voice service enabled on the device that
has MWI Service enabled will trigger the generation of
stutter dial tone if there are new voicemails for the
subscriber on the service provider’s voicemail system. Yes
VMWIEnable Enable VMWI Signal generation. If enabled, any SP voice
service enabled on the device that has VMWI Service
enabled will trigger the generation of VMWI signal if
there are new voicemails for the subscriber on the service
provider’s voicemail system. Yes
CallTransferEnable Enable Call Transfer. Call Transfer, if enabled, is initiated Yes
