SIP User's Manual 6. Configuration Parameters Reference
6.8.9 FXS Call Cut-Through Parameter
The FXS offhook, call cut-through parameter is described in the table below.
Table 6-41: Call Cut-Through Parameter
Parameter Description
Enable Calls Cut
Through
[CutThrough]
Enables FXS endpoints to receive incoming IP calls while the port is in an
off-hook state.
 [0] Disable = Disabled (default).
 [1] Enable = Enabled.
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 party), the device plays a
reorder tone for a user-defined time (configured by the parameter
TimeForReorderTone) 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.
6.8.10 Automatic Dialing Parameters
The automatic dialing upon off-hook parameters are described in the table below.
Table 6-42: Automatic Dialing Parameters

Where,

hooked and no digit is pressed for a user-defined duration
(configured by the parameter HotLineToneDuration), the
destination phone number is automatically dialed.
