This feature supports the inclusion of the SIP Authorization header in initial registration
(REGISTER) requests sent by the device. This feature is enabled by the new
parameter, EmptyAuthorizationHeader.
The Authorization header contains 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 - value of the private user identity
• realm - domain name of the home network
• uri - domain name’s SIP URI of the home network
• nonce - empty value
• response - empty value
This feature complies with registration procedures according to the IMS 3GPP
TS24.229 and PKT-SP-24.220 specifications.
An example of a REGISTER message with an Authorization header is shown below:
REGISTER sip:home1.net SIP/2.0
