Note: For a detailed description of this table, see 'Configuring
Inbound IP Routing Table' on page 317.
Determines whether to route IP calls to the Trunk Group (or IP
Group) before or after manipulation of the destination number
(configured in 'Configuring Source/Destination Number Manipulation
Rules' on page 287).

[0] Route calls before manipulation = (Default) Calls are routed
before the number manipulation rules are applied.

[1] Route calls after manipulation = Calls are routed after the
number manipulation rules are applied.
Determines the device's policy on accepting or blocking SIP calls (IP-
to-Tel calls). This is useful in preventing unwanted SIP calls, SIP
messages, and/or VoIP spam.

[0] Disable = (Default) The device accepts all SIP calls.

[1] Secure Incoming calls = The device accepts SIP calls (i.e.,
calls from the IP side) only from IP addresses that are defined in
the Outbound IP Routing Table or Proxy Set table, or IP
addresses resolved from DNS servers from FQDN values defined
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) that are defined in
the Outbound IP Routing Table table or Proxy Set table, and
rejects all other incoming calls. In addition, if an 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
tables; otherwise, the call is rejected. Therefore, the difference
between this option and option [1] is that this option is concerned
only about numerical IP addresses that are defined in the tables.
Note: If this parameter is set to [1] or [2], when using Proxies or
Proxy Sets, it is 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 addresses are not configured in the
routing table.
Enables filtering of Tel-to-IP calls when a Proxy is used (i.e.,
IsProxyUsed parameter is set to 1 - see 'Configuring Proxy and
Registration Parameters' on page 218).

[0] Don't Filter = (Default) The device doesn't filter calls when
using a Proxy.

[1] Filter = Filtering is enabled.
When this parameter is enabled and a Proxy is used, the device first
checks the Outbound IP Routing Table before making a call through
the Proxy. If the number is not allowed (i.e., number isn't listed in the
table or a call restriction routing rule of IP address 0.0.0.0 is applied),
the call is released.
Note: When no Proxy is used, this parameter must be disabled and
filtering is according to the Outbound IP Routing Table.
