[Freeswitch-users] Restrict SIP registration

[Mehroz Ashraf]

Brian ,It looks interesting but you should be confident enough altering a
FS source code :) , that I wont bother at least. And I guess, you have to
recompile FS each time you are making a change in that string?

A code snippet :
 if (user_agent_filter) {
                if (switch_regex_match(user_agent, user_agent_filter) ==
SWITCH_STATUS_SUCCESS) {
                        if (sofia_test_pflag(profile, PFLAG_LOG_AUTH_FAIL))
{
                                switch_log_printf(SWITCH_CHANNEL_LOG,
SWITCH_LOG_DEBUG,
                                                                  "SIP auth
OK (REGISTER) due to user-agent-filter.  Filter \"%s\" User-Agent
\"%s\"\n", user_agent_filter, user_agent);
                        }
                } else {
                        ret = AUTH_FORBIDDEN;
                        if (sofia_test_pflag(profile, PFLAG_LOG_AUTH_FAIL))
{
                                switch_log_printf(SWITCH_CHANNEL_LOG,
SWITCH_LOG_WARNING,
                                                                  "SIP auth
failure (REGISTER) due to user-agent-filter.  Filter \"%s\" User-Agent
\"%s\"\n", user_agent_filter,

user_agent);
                        }
                        goto end;
                }
        }

 can block a specific User-agent comparing that value in the first nested
IF condition.
But my vote goes to xml_curl method !
