SIP UA configurations are simple. You can identify most of the problems, if there is
any, by viewing configuration and debugging information.
The following are some problems that you may encounter:
"Failed to Set Up Calls in the Proxy Server Approach to SIP Routing" on page
■
2382
"Failed to Register with the Registrar" on page 2382
■
"Failed to Set Up Point-to-Point Calls" on page 2383
■
"Failed to Send REGISTER Requests" on page 2383
■
Symptom
The UA could not set up calls when the proxy server approach was adopted to SIP
routing.
Solution
Do the following:
Perform the display current-configuration command to check for
■
information about the SIP proxy server.
If the proxy server is not configured, configure it in SIP client view.
■
Symptom
The UA could not register with the registrar.
Solution
Check that:
A route to the registrar is available.
■
The local configuration is consistent with that of the registrar.
■
A SIP authentication password is configured by using the user command on
■
the voice gateway if authentication is necessary.
The configuration of realm in the authentication information is consistent with
■
that on the registrar. If the realm argument is locally configured, you must
ensure that the local configuration is the same as that on the registrar.
Otherwise, the voice gateway will not initiate an authentication request. If the
realm argument is not locally configured, the voice gateway will not judge the
configuration of realm on the server and consider the server is trusty.
