Configuring ISDN caller identification callback with C-DCC
Configuring ISDN caller identification callback with C-DCC involves configuring
the server end and the client end.
1 Configure the client of ISDN caller identification callback
Follow these steps to configure the client of ISDN caller identification callback:
To do...
Enter system view
Enter dial interface (physical
or dialer) view
Configure a destination
address and dial string
Set the interval between two
calls
2 Configure the server of ISDN caller identification callback
Follow these steps to configure the server of ISDN caller identification callback:
To do...
Enter system view
Enter dial interface (physical
or dialer) view
Configure the local end to
place ISDN return calls for the
specified ISDN calling number
Configure one or multiple
destination addresses and dial
strings
Use this command instead of
the dialer route command if
only one remote destination
address is involved
n
To make a successful callback for an incoming number, ensure that the dial
■
string configured in the dialer route or dialer number command on the dial
interface at the server end is exactly the same as the incoming number.
To leave enough time for a server to call back, the interval between two calls
■
on the client need to be at least 10 seconds longer than that of the server. It is
recommended that the interval on the server be set to 5 seconds (the default)
and that on the client be set to 15 seconds.
Use the command...
system-view
interface interface-type
interface-number
dialer route protocol
next-hop-address [ mask
network-mask-length ] [ user
hostname | broadcast ] *
dial-number [ autodial |
