Description
Secure Calls
from IP Enum
Disable,
SecureIncomingC
alls,SecureAllCalls
Instant Determines the device’s handling (allowing
or rejecting) of the receipt of IP calls. This
feature is useful for preventing unwanted
SIP calls, SIP messages, and/or VoIP
spam.

[0] Disable = The device accepts all SIP
calls (default).

[1] Secure Incoming Calls = The device
accepts SIP calls only from IP
addresses defined in the 'Outbound IP
Routing’ table/’Tel to IP Routing' or
Proxy Set table, or IP addresses
resolved from DNS servers from FQDN
which appear in the Proxy Set table. All
other incoming calls are rejected.

[2] Secure All Calls = The device
accepts SIP calls only from IP
addresses (in dotted-decimal notation
format) defined in the 'Outbound IP
Routing’ table or Proxy Set table, and
rejects all other incoming calls. In
addition, if a fully-qualified domain name
(FQDN) is defined in the routing table or
Proxy Set table, the call is allowed to be
sent only if the resolved DNS IP
address appears in one of these table;
otherwise it is rejected.
Note: If the parameter is set to [2], when
using Proxies or Proxy Sets, it’s
unnecessary to configure the Proxy IP
addresses in the routing table. The device
allows SIP calls received from the Proxy IP
addresses even if these are not configured
in the routing table.
Filter Calls to IP Enum
No, Yes Instant Enables or disabled filtering for outgoing IP
calls. When enabled, the Gateway routes
calls only to the IP addresses specified in
the Tel to IP routing table. Calls to
unknown IP addresses are rejected.
Max Number of
Active Calls Integer
1 – 2016 Instant Defines the maximum number of calls that
the gateway can have active at the same
time.
