The first (D*) group matches the numbers before the Pound (hash) sign and the second (D*) group
matches the number after the Pound sign. Therefore in the
Call out number
field, $1 will replace the first
(D*) group, $2 will replace the second (D*) group after the # sign (the TCS-4 extension) and the ! sign will
indicate to the second ISDN gateway that the first part is an ISDN number and the second portion is the
TCS-4 extension. In this example, the first ISDN gateway will call out 456!789 to the second ISDN
gateway which will receive it as a TCS-4 request (see below)
Set up the second ISDN gateway with an ISDN to IP dial plan:
o
Called number match
: 456
o
Action
:
Enter the auto att TCS-4
The second ISDN gateway treats 456!789 as a TCS-4 request and any digits after “!” as the TCS-4
extension. It matches 456 to this dial plan and calls the TCS-4 extension 789 to connect to the IP
endpoint
For the ISDN to IP TCS-4 dialing rule, you have to use *, # or ## to separate the ISDN number and the
TCS-4 extension depending on the ISDN endpoint manufacturer. However, in this case, when you are
dialing from the IP endpoint to the first ISDN gateway, you can either use * or # irrespective of the
endpoint you’re using. For example, when you dial 123456#789 from the IP endpoint, you could also dial
123456*789. In the latter case, simply change the
Called number match
of the first ISDN gateway from
123(D*)P(D*) to 123(D*)S(D*) (S denotes *).
Notes:
It is not possible to send alphanumeric characters as a TCS-4 extension from the IP side. That is,
you cannot dial 123456*MCU or 123456#MCU from an IP endpoint because the extension
number (after the * or #) is parsed by the dial plan and there is no way to match letters in the
Called number matches
field. Therefore the $1 and $2 groups on the dial plan of the first ISDN
gateway would only match numbers and not characters.
It is not possible to send an IP address as a TCS-4 extension from the IP endpoint to the first
ISDN gateway.

The dial plan rule below forwards any some calls from the ISDN network to an auto attendant on the
Cisco TelePresence MCU. It allows for some calls to arrive with a TCS-4 extension. It has a catch all rule
that forwards other calls to an operator.
The dial plan shown below is the ISDN to IP dial plan:
