Configuring Isdn Caller Identification Callback - 3Com 3032 Configuration Manual

Configuring ISDN Caller
Identification Callback
By default, the system does not enable callback function and is not configured
with any Windows NT server callback dial number.
2 Configure the PPP callback server in the resource-shared DCC implementation
When resource-shared DCC are adopted to implement PPP callback, the PPP
authentication configuration at server end is the same as that of circular DCC,
except that the server in the resource-shared DCC implementation can only
originate a return call according to the dial number configured in the
command. See "Configure the PPP callback server in the
callback-number
circular DCC implementation" in Dial-up.
Use the
local-user callback-number
and callback dial number in system view, and perform other configurations in
dialer interface view.

In an ISDN environment, implementing DCC callback through the ISDN caller
identification function requires no authentication, nor are there other
configurations requirements.
Features of ISDN caller identification callback
In the applications of ISDN caller identification callback, the callback server can process
a incoming call in three ways, depending on the matching result of the calling number
and the dialer call-in command at the local end:
Denies the incoming call: The
but no match is found for the dial-in number and the configured dialer callers.
Accepts the incoming call: The
or a match is found for the dial-in number and a
configured without the keyword "callback".
Calls back: The
dialer call-in
is found for the dial-in number and a
with the keyword callback.
The best match for the incoming number and the
determined on the basis of right-most matching. The character "
represents any characters. If multiple
incoming number, the following rules will apply for determining the best match:
Primary rule: The best match is the number with the fewest "
