Registrar Configuration
SIP devices can communicate directly if the URL of both devices is known, but in general, SIP gateways are used
in a network to enable functionalities such as routing, registration, authentication, and authorization.
Registration at a registrar server can be useful because in many cases, only the SIP address of a user is known
but the location (SIP address of the device) is unknown or may change. A registrar server keeps track of the
location of user agents from which the registrar server has received REGISTER requests. Thus, only the SIP
address of the user needs to be sent to the registrar server, which then returns one or more contact addresses
of the user.
If the Dialogic

as soon as it is active. Thus, all local addresses configured for registration are registered with the server. You
may use either a private registrar service or a public registrar server.

right hand side. To open the online help for a specific parameter, click the parameter and a window with the help
