Valid Range and Description
PSTNPrefix = a,b,c,d,e
a = Destination Number Prefix
b = Trunk group ID (1 to 99)
c = Source Number Prefix
d = Source IP address (obtained from the Contact header in the INVITE
message)
e = IP Profile ID (1 to 4)
Selection of trunk groups (for IP to Tel calls) is according to destination
number, source number and source IP address.
To support the 'in call alternative routing' feature, users can use
two entries that support the same call, but assigned it with a
different trunk groups. The second entree functions as an
alternative selection if the first rule fails as a result of one of the
release reasons listed in the AltRouteCauseIP2Tel table.
An optional IP ProfileID (1 to 4) can be applied to each routing
rule.
The Source IP Address can include the 'x' wildcard to represent
single digits. For example: 10.8.8.xx represents all IP addresses
between 10.8.8.10 to 10.8.8.99. The '*' wildcard represents 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 field includes an FQDN, DNS resolution is
performed according to DNSQueryType.
0 = Don't remove prefix (default)
1 = Remove PSTN prefix (defined in the IP to Trunk Group routing table)
from a telephone number of an incoming IPàTel call, before forwarding it to
PSTN.
For example:
To route an incoming IPàTel Call with destination number 21100, the IP to
Trunk Group Routing table is scanned for a matching prefix. If such prefix is
found, 21 for instance, then before the call is routed to the corresponding
trunk group the prefix (21) is removed from the original number, so that only
100 is left.
Applicable only if number manipulation is performed after call
routing for IPàTel calls (RouteModeIP2Tel = 0).
0 = Route calls before number manipulation (default)
1 = Route calls after number manipulation
Defines order between routing calls to Trunk group and manipulation of
destination number
0 = Route calls before number manipulation (default)
1 = Route calls after number manipulation
Defines order between routing incoming calls to IP, using routing table, and
manipulation of destination number
Not applicable if Outbound Proxy is used.
