The MTA initially creates a
“
SIP Server list
”
which contains the IP addresses resolved
from the settings
of “Proxy Server”, “SIP
Domai
n” and the “EMS Server”.
See also
below for adding additional Trusted SIP
entities.
Action on Failed
Validation
Drop silently. The MTA simply drops the
incoming SIP request messages.
Reject with 400. The MTA replies with an
error SIP response code of 400 to the
sender.
Additional Trusted
SIP Entities
Input one or more addresses (IP or FQDN)
for additional servers from which the MTA
will accept incoming SIP messages. These
servers are in addition to those in the
“
SIP
Server List
”
which the MTA automatically
creates (see above).
