Configuring Isdn Caller Identification Callback With C-Dcc - HPE FlexNetwork MSR Series Comware 5 Layer 2 - Wan Access Configuration Manual

character. If a dial-in number matches multiple dialer call-in commands, the best match is
selected in the following order:
The one with the fewest asterisks (*).
The one that is found first.
At the server end, identify the dialer call-in commands matching incoming calls.
3.
In C-DCC, upon receipt of an incoming call, the server compares the incoming number
against the dialer call-in commands configured on the physical dialup interface or its
corresponding dialer interface for a match.
In RS-DCC, upon receipt of an incoming call, the server compares the incoming number
against the dialer call-in commands configured on the involved dialer interface for a match.

Configuring ISDN caller identification callback with C-DCC

You can configure the router as the client or server of ISDN caller identification callback with C-DCC.
Configuration guidelines
•
To make a successful callback for an incoming number, make sure that the dial string
configured in the dialer route or dialer number command on the dialup interface at the server
end is exactly the same as the incoming number.
•
To leave enough time for a server to call back, set the interval for DCC to make the next call
attempt on the client at least 10 seconds longer than that of the server. Hewlett Packard
Enterprise recommends that you set interval on the server to 5 seconds (the default) and that
on the client to 15 seconds.
