SIP User's Manual 3. Web-Based Management
Parameter Description
Enable Calls Cut
Through
[CutThrough]
Enables users to receive incoming IP calls while the port is in 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 option is applicable only to FXS interfaces.
Enable User-Information
Usage
[EnableUserInfoUsage]
Enables or disables usage of the User Information loaded to the device in
the User Information auxiliary file. (For a description on User Information,
refer to ''Loading Auxiliary Files'' on page 210.)
[0] Disable = Disabled (default).
[1] Enable = Enabled.
Out-Of-Service Behavior
[FXSOOSBehavior]
Determines the behavior of undefined FXS endpoints as well as all FXS
endpoints when a Busy Out condition exists.
[0] None = Normal operation. No response is provided to undefined
endpoints. A dial tone is played to FXS endpoints when a Busy Out
condition exists.
[1] Reorder Tone = The device plays a reorder tone to the connected
phone / PBX (default).
[2] Polarity Reversal = The device reverses the polarity of the
endpoint, marking it unusable (relevant, for example, to PBX DID
lines). This option can't be configured on-the-fly.
[3] Reorder Tone + Polarity Reversal = Same as 2 and 3 combined.
This option can't be configured on-the-fly.
[4] Current Disconnect = The device disconnects the current of the
FXS endpoint. This option can't be configured on-the-fly.
First Call Ringback Tone
ID
[FirstCallRBTId]
Determines the index of the first Ringback Tone in the CPT file. This
option enables an Application server to request the device to play a
distinctive Ringback tone to the calling party according to the destination
of the call. The tone is played according to the Alert-Info header received
in the 180 Ringing SIP response (the value of the Alert-Info header is
added to the value of this parameter).
The valid range is -1 to 1,000. The default value is -1 (i.e., play standard
Ringback tone).
Notes:
It is assumed that all Ringback Tones are defined in sequence in the
CPT file.
In case of an MLPP call, the device uses the value of this parameter
plus 1 as the index of the Ringback tone in the CPT file (e.g., if this
value is set to 1, then the index is 2, i.e., 1 + 1).
