SIP User's Manual 12. Configuration Parameters Reference
Parameter Description
asterisk ('*') wildcard to represent any number between 0 and
255. For example, 10.8.8.* represents all addresses between
10.8.8.0 and 10.8.8.255.
If the source IP address (SourceAddress) includes an FQDN,
DNS resolution is performed according to the parameter
DNSQueryType.
For available notations for depicting a range of multiple
numbers, see ''Dialing Plan Notation for Routing and
Manipulation'' on page 413.
For a description on using ini file table parameters, see
''Configuring ini File Table Parameters'' on page 368.
Web/EMS: IP to Tel Routing Mode
[RouteModeIP2Tel]
Determines whether to route IP calls to the Hunt Group before or
after manipulation of the destination number (configured in
''Configuring Number Manipulation Tables'' on page 152).
[0] Route calls before manipulation = Calls are routed before
the number manipulation rules are applied (default).
[1] Route calls after manipulation = Calls are routed after the
number manipulation rules are applied.
Web: IP Security
EMS: Secure Call From IP
[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 = The device accepts all SIP calls (default).
[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.
Web/EMS: Filter Calls to IP
[FilterCalls2IP]
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 136).
[0] Don't Filter = device doesn't filter calls when using a
Proxy (default).
[1] Filter = Filtering is enabled.
When this parameter is enabled and a Proxy is used, the device
