SIP Registration
Registration is the process by which centralized SIP Server/Registrars become aware of the
existence and readiness of an endpoint to make and receive calls. The phone supports a num-
ber of configuration parameters to allow this to happen. Registration can be authenticated or
un-authenticated depending on how the server and phone is configured.
For operation with an OpenScape Voice server, set
Server type
to "OS Voice". When HiQ8000
is to be used, set it to "HiQ8000". The expiry time of a registration can be specified by
Regis-
tration timer
.
Unauthenticated Registration
For unauthenticated registration, the following parameters must be set on the phone: Terminal
number or Terminal name (see Section 3.6.1.1, “Terminal Identity”), SIP server and SIP regis-
trar address (see Section 3.6.6.1, “SIP Addresses”).
In unauthenticated mode, the server must pre-authenticate the user. This procedure is server
specific and is not described here.
Authenticated Registration
The phone supports the digest authentication scheme and requires some parameters to be
configured in addition to those for unauthenticated registration. By providing a
User ID
and a
Password
which match with a corresponding account on the SIP registrar, the phone authen-
ticates itself. Optionally, a
Realm
can be added. This parameter specifies the protection do-
main wherein the SIP authentication is meaningful. The protection domain is globally unique,
so that each protection domain has its own arbitrary usernames and passwords.

A challenge from the server for authentication information is not only restricted to the
REGISTER message, but can also occur in response to other SIP messages, e. g.
INVITE.
