Description
■ Analog interfaces: If the parameter is enabled, it is
possible to configure the FXS/FXO interface to wait for
dial tone per destination phone number (before or during
dialing of destination phone number). Therefore, the
parameter IsWaitForDialTone (configurable for the
entire device) is ignored.
■ Analog interfaces: The FXS interface send SIP 200 OK
responses only after the DTMF dialing is complete.
■ The corresponding global parameter is
EnableDigitDelivery.
DialPlanIndex
Enables PSTN CAS channels/endpoints to receive
incoming IP calls even if the B-channels are in off-hook
state.
■ [0] Disable (default)
■ [1] Enable = When enabled, the feature operates as
follows:
a. A Tel-to-IP call is established (connected) by the
device for a B-channel.
b. The device receives a SIP BYE (i.e., IP side ends
the call) and plays a reorder tone to the PSTN side
for the duration configured by the
CutThroughTimeForReOrderTone parameter. The
device releases the call towards the IP side (sends
a SIP 200 OK).
c. The PSTN side, for whatever reason, remains off-
hook.
d. If a new IP call is received for this B-channel after
the reorder tone has ended, the device "cuts
through" the channel and connects the call imme-
diately (despite the B-channel being in physical off-
hook state) without playing a ring tone. If an IP call
is received while the reorder tone is played, the
device rejects the call.
Note:
■ If the parameter is disabled and the PSTN side remains
in off-hook state after the IP call ends the call, the
device releases the call after 60 seconds.
■ A special CAS table can be used to report call status
events (Active/Idle) to the PSTN side during Cut
Through mode (see
■ The corresponding global parameter is
