Mediant 500L MSBR
Parameter Description
CLI: anonymous-mode
[AnonymousMode]
Determines whether the device's IP address is used as the URI host
part instead of "anonymous.invalid" in the INVITE's From header for
Tel-to-IP calls.
 [0] = (Default) If the device receives a call from the Tel with
blocked caller ID, it sends an INVITE with
From: “anonymous”<anonymous@anonymous.invalid>
 [1] = The device's IP address is used as the URI host part instead
of "anonymous.invalid".
This parameter may be useful, for example, for service providers
who identify their SIP Trunking customers by their source phone
number or IP address, reflected in the From header of the SIP
INVITE. Therefore, even customers blocking their Caller ID can be
identified by the service provider. Typically, if the device receives a
call with blocked Caller ID from the PSTN side (e.g., Trunk
connected to a PBX), it sends an INVITE to the IP with a From
header as follows: From: “anonymous”
<anonymous@anonymous.invalid>. This is in accordance with RFC
3325. However, when this parameter is set to 1, the device replaces
the "anonymous.invalid" with its IP address.
EMS: P Asserted User Name
CLI: p-assrtd-usr-name
[PAssertedUserName]
Defines a 'representative number' (up to 50 characters) that is used
as the user part of the Request-URI in the P-Asserted-Identity
header of an outgoing INVITE for Tel-to-IP calls.
The default is null.
EMS: Use URL In Refer To
Header
[UseAORInReferToHeader]
Defines the source for the SIP URI set in the Refer-To header of
outgoing REFER messages.
 [0] = (Default) Use SIP URI from Contact header of the initial call.

[1]
= Use SIP URI from To/From header of the initial call.
Web: Enable User-Information
Usage
CLI: user-inf-usage
[EnableUserInfoUsage]
Enables the usage of the User Information, which is loaded to the
device in the User Information auxiliary file. For a description on User
Information, see ''Loading Auxiliary Files'' on page 615.
 [0] Disable (default)
 [1] Enable
Note: For this parameter to take effect, a device reset is required.
[HandleReasonHeader]
Determines whether the device uses the value of the incoming SIP
Reason header for Release Reason mapping.
 [0] = Disregard Reason header in incoming SIP messages.
 [1] = (Default) Use the Reason header value for Release Reason
mapping.
[EnableSilenceSuppInSDP]
Determines the device's behavior upon receipt of SIP Re-INVITE
messages that include the SDP's 'silencesupp:off' attribute.
 [0] = (Default) Disregard the 'silecesupp' attribute.
 [1] = Handle incoming Re-INVITE messages that include the
'silencesupp:off' attribute in the SDP as a request to switch to the
Voice-Band-Data (VBD) mode. In addition, the device includes
the attribute 'a=silencesupp:off' in its SDP offer.
Note: This parameter is applicable only if the G.711 coder is used.
