Always Auth
Reject
When an incoming INVITE or REGISTER is to be rejected, for any
reason, always reject with an identical response equivalent to
valid username and invalid password/hash instead of letting the
requester know whether there was a matching user or peer for
their request. This reduces the ability of an attacker to scan for
valid SIP usernames. This option is set to 'yes' by default.
Authenticate
Options Requests
Enabling this option will authenticate OPTIONS requests just like
INVITE requests are. By default this option is disabled.
Allow Guest
Calling
Allow or reject guest calls (default is yes, to allow). If your gateway
is connected to the Internet and you allow guest calls, you want
to check which services you offer everyone out there, by enabling
them in the default context.
