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.
