Version 7.2 1183 Mediant 500L Gateway & E-SBC
User's Manual 69. Configuration Parameters Reference
Parameter Description

For the parameter to take effect, a device reset is
required.
configure voip > interface fxs-fxo >
current-disconnect-duration
[CurrentDisconnectDuration]
Defines the duration (in msec) of the current disconnect
pulse.
The range is 200 to 1500. The default is 900.
Note:
 The 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 the parameter is set to
400 msec, then the detection window is 300 to 750 msec.
 For the parameter to take effect, a device reset is
required.
[CurrentDisconnectDefaultThreshold] Defines the line voltage threshold at which a current
disconnect detection is considered.
The valid range is 0 to 20 Volts. The default is 4 Volts.
Note:
 The parameter is applicable only to FXO interfaces.
 For the parameter to take effect, a device reset is
required.
configure voip > interface fxs-fxo >
time-to-sample-analog-line-voltage
[TimeToSampleAnalogLineVoltage]
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 is 1000
msec.
Note:
 The parameter is applicable only to FXO interfaces.
 For the parameter to take effect, a device reset is
required.
69.10.9 Tone Parameters
This subsection describes the device's tone parameters.
69.10.9.1 Telephony Tone Parameters
The telephony tone parameters are described in the table below.
Table 69-61: Tone Parameters
Parameter Description
SIP Hold Behavior
configure voip > sip-definition
settings > sip-hold-behavior
[SIPHoldBehavior]
Enables the device to handle incoming re-INVITE messages
with the "a=sendonly" attribute in the SDP, in the same way as
if an "a=inactive" is received in the SDP. When enabled, the
device plays a held tone to the Tel phone and responds with a
SIP 200 OK containing the "a=recvonly" attribute in the SDP.
