Calling party number routing table

The calling party number (calling-e164) table is used to route calls based on the calling-e164 in the call setup
message. This number in general corresponds to the extension number of a PBX or MSN of an ISDN termi-
nal. The table can be used to route calls from extensions, which have particular call routing requirements (i.e.
Terminals which require non VoIP capable ISDN services). The call router looks for the longest match starting
with the first digit of the calling party number.
Note
The calling party number is sometimes inserted or modified by a PBX.
Sometimes there is no calling party number at all. This all depends on the
equipment you connect to the device.
Note
The T-indicator cannot be used in calling party number tables. (Overlap
dialing only makes sense for called party numbers).
Example: Calling party number routing table
This example shows how to create a calling party number routing table that routes calls based on the last three
digits of the calling party number (the extension part). The key .%52[35]$ means that every number that starts
with any digit (.) appearing zero or more times (%) followed by 52 and a 3 or 5 matches the entry. For exam-
ple, the following calling party numbers match the first entry: 0998882523 or 0998882525 or simply 523 or
525.
378
All entries match the dialed number of 111, but entry #4 matches best because
the expression is more precise (longer) than entry #1-#3. Entry #4 is selected
but the call is not placed immediately because the entry contains the T-indica-
tor. The router waits for additional digits and then places call to interface IF4
when the digit-collection timeout elapses.
Note: If the user enters an additional digit during digit-collection on a T-indica-
tor, the router must not change the destination entry anymore.
Entry #1, #2 and #3 match the dialed number of 112. Entry #1 has only an
expression of one digit while entry #2 and #3 have an expression that specify
two digits. Entry #3 matches better than entry #2 because entry #3 explicitly
specifies the digits while entry #2 contains a wildcard for the second digit. Thus
entry #3 is selected and the call is placed immediately to interface IF3.
Entry #1 and #2 match the dialed number of 121, but entry #2 matches better.
The call is immediately placed to IF2.
Only entry #1 matches the dialed number of 191. Thus the call is routed imme-
diately to interface IF1.
The lookup procedure is the same as for dialled number 111. The call router
waits for additional digits and places the call after the digit-collection timeout to
interface IF4.
Same as for 1111, but the pound (#) terminates the digit collection; the call is
immediately placed to interface IF4.
