Parameter Description
CLI: reg-on-conn-failure
[ReRegisterOnConnectionFailure]

[1] Enable
CLI: expl-un-reg
[UnregistrationMode]
Enables the device to perform explicit unregisters.
 [0] Disable (default)
 [1] Enable = The device sends an asterisk ("*") value in the
SIP Contact header, instructing the Registrar server to
remove all previous registration bindings. The device
removes SIP User Agent (UA) registration bindings in a
Registrar, according to RFC 3261. Registrations are soft
state and expire unless refreshed, but they can also be
explicitly removed. A client can attempt to influence the
expiration interval selected by the Registrar. A UA requests
the immediate removal of a binding by specifying an
expiration interval of "0" for that contact address in a
REGISTER request. UA's should support this mechanism
so that bindings can be removed before their expiration
interval has passed. Use of the "*" Contact header field
value allows a registering UA to remove all bindings
associated with an address-of-record (AOR) without
knowing their precise values.
Note: The REGISTER-
specific Contact header field value of "*"
applies to all registrations, but it can only be used if the Expires
header field is present with a value of "0".
Web/EMS
: Add Empty Authorization
Header
CLI: add-empty-author-hdr
[EmptyAuthorizationHeader]
Enables the inclusion of the SIP Authorization header in initial
registration (REGISTER) requests sent by the device.
 [0] Disable (default)
 [1] Enable
The Authorization header carries the credentials of a user

message populates the Authorization header with the following
parameters:
 username - set to the value of the private user identity
 realm - set to the domain name of the home network
 uri - set to the SIP URI of the domain name of the home
network
 nonce - set to an empty value
 response - set to an empty value
For example:
Authorization: Digest
username=alice_private@home1.net,
realm=”home1.net”, nonce=””,
response=”e56131d19580cd833064787ecc”
Note: This registration header is according to the IMS 3GPP
TS24.229 and PKT-SP-24.220 specifications.
Web: Add initial Route Header
CLI: add-init-rte-hdr
[InitialRouteHeader]
Enables the inclusion of the SIP Route header in initial
registration or re-registration (REGISTER) requests sent by the
device.
 [0] Disable (default)
 [1] Enable
When the device sends a REGISTER message, the Route
header includes either the Proxy's FQDN, or IP address and
