Setting up dial plan rules when using TCS-4

TCS-4 is a protocol that only applies to H.320 video calls and is a method of signaling an extension
number after an H.320 call has been established. By using a TCS-4 extension to pass the extra digits to
the ISDN gateway, customers can dial from a predefined endpoint phone list, rather than entering the
extension using DTMF in the auto attendant.

ISDN to IP calls

There is a new Action in the ISDN to IP dial plan: Enter the auto attendant + TCS-4. When used, the call
enters the auto attendant and sends a TCS-4 request; when the auto attendant receives the reply, it dials
out the TCS-4 extension. Usually the TCS-4 reply is fast enough that the ISDN gateway auto-attendant is
not displayed; however, you may see it briefly with the TCS-4 extension shown.
To send a TCS-4 extension:
•
from a Cisco endpoint, dial the ISDN number followed by a * and then enter the TCS-4 extension.
For example, if the ISDN gateway TCS-4 dial plan incoming number match is 1234 and the
required TCS-4 extension is 5678, dial 1234*5678 from your Cisco endpoint. The ISDN gateway
will then connect to the TCS-4 dial plan and dial out 5678 from the ISDN gateway auto attendant
without you having to enter the extension via DTMF

Example dial plan rules
This rule allows a caller to
connect to a PIN protected
audio conference on an audio
bridge.
In this example, the audio
bridge will answer the call.
After a two second pause the
ISDN gateway sends the
DTMF tones for the conference
ID (555); these are the digits
after the exclamation mark (!)
which indicates where the
number to dial ends and the
DTMF tones begin. There is a
four second pause
(represented by two commas)
and then the ISDN gateway
sends the PIN (888). The audio
bridge requires a caller to press
pound/hash after the ID and
the PIN; these are represented
with 'P'.
This rule catches any other
called number and will place it
as a video-conferencing call
(that is video and voice) using
the lowest bandwidth.
