Match Auth
Username
If available, match user entry using the 'username' field from the
authentication line instead of the 'from' field.
Realm
Realm for digest authentication. Realms MUST be globally unique
according to RFC 3261. Set this to your host name or domain name.
Use Domain as
Realm
Use the domain from the SIP Domains setting as the realm. In this case,
the realm will be based on the request 'to' or 'from' header and should
match one of the domain. Otherwise, the configured 'realm' value will be
used.
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.
