VERVIEW
A UA registers with the registrar by sending a REGISTER request containing such
information as address, route, and number. Thus, when it is called by some other
UA through a proxy server, the proxy server can consult the registrar for its
registration information.
The basic functions that a UA must have are to initiate session requests as a caller
and make responses as a callee. After a user attached to a UA-supported router
working as UA dials a number, the router sends a session request to the called UA
as a caller either directly or through one or more proxy servers.
SIP authentication information is required in the following two cases:
User agents (UAs) use a proxy server and the proxy server needs to authenticate
■
UAs.
The peer SIP device needs to authenticate the local device during SIP message
■
exchange.
Authentication information selection rule
The authentication information, if configured by using the user command, in
POTS entity view is preferred. Otherwise, the authentication information
configured in SIP client view is used.
CAUTION:
If realm is configured on the SIP UA, ensure that the value is the same as that
■
configured on the server. Otherwise, the SIP UA will fail the authentication due
to mismatch. If realm is not configured on a SIP UA, the SIP UA will perform no
realm match and consider that the value of realm configured on the server is
trusted.
If it is necessary to configure authentication information in POTS entity view,
■
the same authentication information is recommended for the POTS entities
configured with the same telephone number.
In the case of authentication, it is forbidden to execute the user command
■
after the registration function is enabled because this operation may result in a
registration update failure.
Configuration prerequisites
The configuration on the SIP server is completed.
