Flash Lengths
Accepted Flash Length:
These options control the Flash length allowed from a Local Extension
that TalkSwitch considers to be an intentional Flash. The range can be
adjusted to accept anything from 300 ms to 1 second. The default range
for accepting a Flash signal at a Local Extension is between 400 ms and
800 ms. Most phones emit a 600 ms Flash signal when the 'Flash' or 'Link'
button is pressed.
Transmitted Flash Length:
This option controls the transmitted Flash length from TalkSwitch to the
Telephone Company lines. TalkSwitch emits a Flash when forwarding or
bridging calls using the 3-Way Calling/Conference or Centrex Transfer
service, or when transferring calls through an existing PBX system. The
value can be adjusted from 250 ms to 1 second. The default setting is 400
ms. If you notice that you are having problems with any of the
TalkSwitch features that use 3-way calling, experiment with this value.
Double Flash time
When two flashes are detected, TalkSwitch needs to calculate the time
between the flashes to establish if they were intended to propagate a flash
at the CO or to place a call on hold and then quickly retrieve it. The Double
Flash time values signify the maximum time between two flashes that
TalkSwitch recognizes as an intended flash to the CO. When two flashes are
detected with a time gap larger than the value displayed, no flash is
propagated at the CO. The value can be adjusted from 200 ms to 2000 ms
with the default set at 1200 ms.
3-Way Calling wait time
This option adjusts the time required between flash hook and a dial string.
Some telephone company 3-Way Calling/Conference services require
different time allowances after the flash signal to re-establish dial tone. The
default time is 2 seconds so TalkSwitch can let the lines settle after going off
hook before sending the DTMF digits.
Ring Patterns
Click the 'Check Ring Pattern...' button and call any extension. After three
rings the sequence of the ring pattern displays in a new window. The time is
displyed in milliseconds.
