Parameter Description
'Contact Restriction'
contact-restriction
[EnableContactRestrictio
n]
Determines whether the device sets the Contact header of
outgoing INVITE requests to ‘anonymous’ for restricted calls.
■ [0] Disable (default)
■ [1] Enable
configure voip >
sip-definition
settings >
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".
The 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” <anonym-
ous@anonymous.invalid>". This is in accordance with RFC
3325. However, when the parameter is set to 1, the device
replaces the "anonymous.invalid" with its IP address.
configure voip >
sip-definition
settings > 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.
configure voip >
sip-definition
settings > use-aor-
in-refer-to-header
[UseAORInReferToHead
er]
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.
'User-Information Usage'
configure voip >
sip-definition
settings > user-
inf-usage
[EnableUserInfoUsage]
Enables the usage of the User Information, which is loaded to the
device in the User Information Auxiliary file. For more information
on User Information, see User Information File.
■ [0] Disable (default)
■ [1] Enable
Note: For the parameter to take effect, a device reset is required.
configure voip >
sip-definition
settings > handle-
reason-header
[HandleReasonHeader]

Reason mapping.
