Call Cut-Through Parameters
Parameter Description
Web: Enable Calls Cut
Through
EMS: Cut Through
CLI: calls-cut-through
[CutThrough]
Enables FXS endpoints to receive incoming IP calls while the port is in
off-hook state.
 [0] Disable (default)
 [1] Enable
If enabled, the FXS interface answers the call and 'cuts through' the voice
channel if there is no other active call on the port, even if the port is in off-
hook state.
When the call is terminated (by the remote IP party), the device plays a
reorder tone for a user-defined time (configured by the
CutThroughTimeForReorderTone parameter) and is then ready to answer
the next incoming call without on-hooking the phone.
The waiting call is automatically answered by the device when the current
call is terminated (configured by setting the parameter EnableCallWaiting
to 1).
Note: This feature is applicable only to FXS interfaces.
CLI: cut-through-anable
[DigitalCutThrough]
Enables PSTN CAS channels/endpoints to receive incoming IP calls even
if the B-channels are in off-hook state.
 [0] Disabled (default)
 [1] Enabled
When enabled, this feature operates as follows:
1 A Tel-to-IP call is established (connected) by the device for a B-
channel.
2 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 set by the
CutThroughTimeForReOrderTone parameter. The device releases the
call towards the IP side (sends a SIP 200 OK).
3 The PSTN side, for whatever reason, remains off-hook.
4 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
immediately (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.
Notes:
 If this 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.
 This feature can also be configured in a Tel Profile and therefore,
assigned to specific B-channels that use specific CAS tables.
