'Add initial Route Header'
Parameter Description
■ [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".
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 agent (UA) in a request to a server. The sent
REGISTER 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.
Enables the inclusion of the SIP Route header in initial
registration or re-registration (REGISTER) requests
sent by the device.
■ [0] Disable (default)
