SIP User's Manual 6. Configuration Parameters Reference
Parameter Description
Web: IP Security
EMS: Secure Call From IP
[SecureCallsFromIP]
Determines whether the device accepts SIP calls only from
configured SIP Proxies or IP addresses defined in the 'Tel to IP
Routing' table (refer to ''Configuring the Tel to IP Routing Table''
on page 131). This is u
seful in preventing unwanted SIP calls,
SIP messages, and/or VoIP spam.
[0] Disable = The device accepts all SIP calls (default).
[1] Enable = The device accepts SIP calls only from IP
addresses defined in the 'Tel to IP Routing' table and rejects
all other calls.
Notes:
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.
This feature is supported only for numerical IP addresses in
the 'Tel to IP 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 - refer to ''Configuring Proxy
and Registration Parameters'' on page 94).
[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
first checks the 'Tel-to-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 'Tel-to-IP Routing' table.
[IP2TelTaggingDialPlanIndex]
Determines the Dial Plan index in the external Dial Plan file
(*.dat) in which string labels ("tags") are defined for tagging
incoming IP-to-Tel calls. The special “tag” is added as a prefix to
the called party number, and then the 'IP-to-Hunt Group Routing'
table uses this “tag” instead of the original prefix. Manipulation is
then performed (after routing) in the Manipulation table, which
strips the “tag” characters before sending the call to the
endpoint.
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).
The routing label can be up to 9 (text) characters.
Notes:
The routing must be configured to be performed before
manipulation.
For a detailed description of this feature, refer to ''Dial Plan
Prefix Tags for IP-to-Tel Routing'' on page 381.
