Parameter Description
with an SDP.
 [1]
Enable = The device sends the initial INVITE message without an
SDP.
[DisableCryptoLifeTimeI
nSDP]
Enables the device to send "a=crypto" lines without the lifetime
parameter in the SDP. For example, if the SDP contains "a=crypto:12
AES_CM_128_HMAC_SHA1_80
inline:hhQe10yZRcRcpIFPkH5xYY9R1de37ogh9G1MpvNp|2^31", it
removes the lifetime parameter "2^31".
 [0] Disable (default)
 [1] Enable
Web/EMS: Enable
Contact Restriction
[EnableContactRestricti
on]
Determines whether the device sets the Contact header of outgoing
INVITE requests to ‘anonymous’ for restricted calls.
 [0] Disable (default)
 [1] Enable
[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
[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
[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.
Web: Enable User-
Information 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 399.
 [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
