Mediant 1000B Gateway & E-SBC
Parameter Description
IP-to-Tel Routing
configure voip > gateway routing
ip2tel-routing
[PSTNPrefix]
Defines the routing of IP-to-Tel routing rules.
The format of the ini file table parameter is as follows:
[PSTNPrefix]
FORMAT PstnPrefix_Index = PstnPrefix_RouteName,
PstnPrefix_DestPrefix, PstnPrefix_TrunkGroupId,
PstnPrefix_SourcePrefix, PstnPrefix_SourceAddress,
PstnPrefix_ProfileName, PstnPrefix_SrcIPGroupName,
PstnPrefix_DestHostPrefix, PstnPrefix_SrcHostPrefix,
PstnPrefix_SrcSIPInterfaceName, PstnPrefix_TrunkId,
PstnPrefix_CallSetupRulesSetId, PstnPrefix_DestType;
[\PSTNPrefix]
For a detailed description of the table, see ''Configuring IP-to-
Tel Routing Rules'' on page 484.
IP to Tel Routing Mode
configure voip > gateway routing
settings > ip2tel-rte-mode
[RouteModeIP2Tel]
Determines whether to route IP calls to the Trunk Group
before or after manipulation of the destination number
(configured in ''Configuring Source/Destination Number
Manipulation Rules'' on page 503).
 [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.
IP Security
configure voip > sip-definition
settings > ip-security
[SecureCallsFromIP]
Determines the device's policy on accepting or blocking SIP
(IP) 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
only from IP addresses that are configured in the Tel-to-IP
Routing table or Proxy Sets table, or IP addresses resolved
from DNS servers from FQDN values configured in the
Proxy Sets 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 Tel-to-IP Routing table or Proxy Sets
table, and rejects all other incoming calls. In addition, if an
FQDN is defined in the routing table or Proxy Sets 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 the 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.
Filter Calls to IP
configure voip > sip-definition
settings > 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 the 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.,
