Mediant 500 E-SBC
Parameter Description
Number Manipulation Rules'' on page 361 ).

[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.
Web: IP Security
EMS: Secure Call From IP
CLI: ip-security
[SecureCallsFromIP]
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 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.
Web/EMS: Filter Calls to IP
CLI: filter-calls-to-ip
[FilterCalls2IP]
Enables filtering of Tel-to-IP calls when a Proxy Set is used.

[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.
Web: IP-to-Tel Tagging Destination
Dial Plan Index
CLI: ip2tel-tagging-dst
[IP2TelTaggingDestDialPlanIndex] Defines the Dial Plan index in the Dial Plan file for called
prefix tags for representing called number prefixes in
Inbound Routing rules.
The valid values are 0 to 7, where 0 denotes PLAN1, 1
denotes PLAN2, and so on. The default is -1 (i.e., no dial
plan file used).
