MP-500 MSBG
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
201 ). This is useful in preventing unwanted SIP calls,
SIP messages, and/or VoIP spam.
ƒ
[0] Disable = The device accepts all SIP calls (default).
ƒ
[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:
ƒ
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.
ƒ
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
147 ).
ƒ
[0] Don't Filter = device doesn't filter calls when using a
Proxy. (default)
ƒ
[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.
