SIP User's Manual 6. ini File Configuration
Table 6-12: Number Manipulation and Routing Parameters
ini File Field Name
Web Parameter Name
Valid Range and Description
ENUM query containing the destination phone number is sent to the
DNS server. The ENUM reply includes a SIP URI, used as the
Request-URI in the outgoing INVITE and for routing (if Proxy is not
used).
 For detailed information on this feature and for configuring the Tel to
IP Routing table using the Embedded Web Server, refer to 'Tel to IP
Routing Table' on page 122.
For available notations, refer to 'Dialing Plan Notation' on page 116.
PSTNPrefix
Configures the routing of IP-to-Tel calls to Trunk groups (also
configured in the Embedded Web Server's 'IP to Trunk Group Routing
Table' screen -- refer to 'IP to Trunk Group Routing' on page 126).
Format of this ini file parameter table:
[PSTNPrefix]
FORMAT PSTNPrefix_Index = PSTNPrefix_DestPrefix,
PSTNPrefix_TrunkGroupId, PSTNPrefix_SourcePrefix,
PSTNPrefix_SourceAddress, PSTNPrefix_ProfileId;
[\PSTNPrefix]
Where,
 DestPrefix = Destination number prefix
 TrunkGroupId = Trunk group ID (1 to 99)
 SourcePrefix = Source number prefix
 SourceAddress = Source IP address (obtained from the Contact
header in the INVITE message)
 ProfileId = optional IP Profile ID (1 to 4) that can be applied to each
routing rule
For example:
[PSTNPrefix]
PSTNPrefix 0 = 10, 2,*,10.13.8.9, 1;
[\PSTNPrefix]
Notes:
 To support the In-Call Alternative Routing feature, you can use two
entries that support the same call, but assigned with a different
Trunk group. The second entry functions as an alternative selection
if the first rule fails as a result of one of the release reasons listed in
the AltRouteCauseIP2Tel table.
 Selection of Trunk groups (for IP-to-Tel calls) is according to
destination number, source number,and source IP address.
 The source IP address (SourceAddress) can include the 'x' wildcard
to represent single digits. For example: 10.8.8.xx represents all IP
addresses between 10.8.8.10 and 10.8.8.99.
 The source IP address (SourceAddress) can include the 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 DNSQueryType.
 This parameter can appear up to 24 times.
