SIP User's Manual A. Configuration Parameters Reference
Parameter Description
For this parameter to take effect, a device reset is required.
EMS: Current Disconnect
Duration
[CurrentDisconnectDuration]
Defines the duration (in msec) of the current disconnect pulse.
The range is 200 to 1500. The default is 900.
Notes:
This parameter is applicable for FXS and FXO interfaces.
The FXO interface detection window is 100 msec below the
parameter's value and 350 msec above the parameter's value.
For example, if this parameter is set to 400 msec, then the
detection window is 300 to 750 msec.
For this parameter to take effect, a device reset is required.
[CurrentDisconnectDefaultThre
shold]
Defines the line voltage threshold at which a current disconnect
detection is considered.
The valid range is 0 to 20 Volts. The default value is 4 Volts.
Notes:
This parameter is applicable only to FXO interfaces.
For this parameter to take effect, a device reset is required.
[TimeToSampleAnalogLineVolt
age]
Defines the frequency at which the analog line voltage is sampled
(after offhook), for detection of the current disconnect threshold.
The valid range is 100 to 2500 msec. The default value is 1000
msec.
Notes:
This parameter is applicable only to FXO interfaces.
For this parameter to take effect, a device reset is required.
A.12.9 Tone Parameters
This subsection describes the device's tone parameters.
A.12.9.1 Telephony Tone Parameters
The telephony tone parameters are described in the table below.
Table A-61: Tone Parameters
Parameter Description
[EnableMOH]
Enables the option for using an external audio source that is connected
to the device's AUDIO connector (on the CPU module). When enabled,
the device uses the incoming audio from this connector instead of
playing the Held Tone defined in the Call Progress Tones (CPT) file.
[0] = Disable (default).
[1] = Enable.
Note: EnableHold must be set to 1 to enable this feature.
[PlayHeldToneForIP2IP]
Enables playing a Held tone to an IP-to-IP leg instead of putting it on
hold.
[0] = Disabled. The device interworks the re-INVITE with a=inactive
from one SIP leg to another SIP leg. (default)
[1] = Enabled. The device plays a Held tone to the IP if it receives a
re-INVITE with a=inactive in the SDP from the party initiating the call
