Version 7.2 1069 Mediant 500 MSBR
User's Manual 74. Configuration Parameters Reference
[PSTNAlertTimeout] call and sends a SIP 408 request timeout response to the SIP party that
initiated the call.
Analog: Defines the Alert Timeout (in seconds) for calls to the Tel side.
This timer is used between the time a ring is generated (FXS) or a line
is seized (FXO), until the call is connected. For example: If the FXS
device receives an INVITE, it generates a ring to the phone and sends
a SIP 180 Ringing response to the IP. If the phone is not answered
within the time interval set by the parameter, the device cancels the call
by sending a SIP 408 response.
The valid value range is 1 to 600 (in seconds). The default is 180.
Note: (Digital interfaces) If per trunk configuration (using
TrunkPSTNAlertTimeout) is set to other than default, the
PSTNAlertTimeout parameter value is overridden.
RTP Only Mode
configure voip > sip-
definition settings > rtp-
only-mode
[RTPOnlyMode]
Enables the device to send and receive RTP packets to and from
remote endpoints without the need to establish a SIP session. The
remote IP address is determined according to the Tel-to-IP Routing
table (Prefix parameter). The port is the same port as the local RTP port
(configured by the BaseUDPPort parameter and the channel on which
the call is received).

[0] Disable (default)

[1] Transmit & Receive = Send and receive RTP packets.

[2] Transmit Only= Send RTP packets only.

[3] Receive Only= Receive RTP packets only.
Note:

The parameter is applicable only to the Gateway application.

Digital interfaces: To activate the RTP Only feature without using
ISDN / CAS signaling, you must do the following:

Configure E1/T1 Transparent protocol type (set the ProtocoType
parameter to 5 or 6).

Enable the TDM-over-IP feature (set the EnableTDMoverIP
parameter to 1).

To configure the RTP Only mode per trunk, use the
RTPOnlyModeForTrunk_x parameter.

If per trunk configuration (using the RTPOnlyModeForTrunk_ID
parameter) is set to a value other than the default, the
RTPOnlyMode parameter value is ignored.
[RTPOnlyModeForTrunk_
x] Enables the RTP Only feature per trunk. The x in the parameter name
denotes the trunk number, where 0 is Trunk 1. For a description of the
parameter, see the RTPOnlyMode parameter.
Note: For using the global parameter (i.e., setting the RTP Only feature
for all trunks), set the parameter to -1 (default).
Media IP Version
Preference
media-ip-ver-pref
[MediaIPVersionPreferenc
e]
Global parameter that defines the preferred RTP media IP addressing
version (IPv4 or IPv6) for outgoing SIP calls. You can also configure this
feature per specific calls, using IP Profiles
(IpProfile_MediaIPVersionPreference). For a detailed description of the
parameter and for configuring this feature in the IP Profiles table, see
Configuring IP Profiles on page 404.
SIT Q850 Cause
configure voip > sip-
definition settings > sit-
q850-cause
Defines the Q.850 cause value specified in the SIP Reason header that
is included in a 4xx response when a Special Information Tone (SIT) is
detected on an IP-to-Tel call.
The valid range is 0 to 127. The default is 34.
