Description
Remove Prefix on IP to
Tel Calls
Enum
No, Yes
Instant Determines whether the gateway removes
the prefix from the destination number for
IP-to-Tel calls.
No – Don't remove prefix
Yes – Remove the prefix (defined in the
'IP to Trunk Group Routing' table) from a
telephone number for an IP-to-Tel call,
before forwarding it to Tel.
For example: To route an incoming IP-to-
Tel call with destination number 21100, the
'IP to Trunk Group Routing' table is scanned
for a matching prefix. If such a prefix is
found (e.g., 21), then before the call is
routed to the corresponding Trunk Group,
the prefix (21) is removed from the original
number, and therefore, only 100 remains.
Notes:
Applicable only if number manipulation is
performed after call routing for IP-to-Tel
calls (i.e., IP to TEL Routiung Mode is set to
Route Before Map).
Similar operation (of removing the prefix) is
also achieved by using the usual number
Operation rules.
