Information Usage
Version 6.4
Determines the device's response to an incoming SDP that includes
an IP address of 0.0.0.0 in the SDP's Connection Information field
(i.e., "c=IN IP4 0.0.0.0").

[0] = Sets the IP address of the outgoing SDP's c= field to 0.0.0.0
(default).

[1] = Sets the IP address of the outgoing SDP c= field to the IP
address of the device. If the incoming SDP doesn't contain the
"a=inactive" line, the returned SDP contains the "a=recvonly" line.
Determines whether the device sends the initial INVITE message with
or without an SDP. Sending the first INVITE without SDP is typically
done by clients for obtaining the far-end's full list of capabilities before
sending their own offer. (An alternative method for obtaining the list of
supported capabilities is by using SIP OPTIONS, which is not
supported by every SIP agent.)

[0] Disable = The device sends the initial INVITE message with an
SDP (default).

[1] Enable = The device sends the initial INVITE message without
an SDP.
Determines whether the device sets the Contact header of outgoing
INVITE requests to 'anonymous' for restricted calls.

[0] Disable (default)

[1] Enable
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.
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 value is null.
Defines the source for the SIP URI set in the Refer-To header of
outgoing REFER messages.

[0] = Use SIP URI from Contact header of the initial call (default).

[1] = Use SIP URI from To/From header of the initial call.
Enables the usage of the User Information, which is loaded to the
device in the User Information auxiliary file. (For a description on User
