the server end and the client end.

Follow these steps to configure the client of ISDN caller identification callback:
To do...
Enter system view
Enter dialer interface view
Configure a dial string for
calling a remote end
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 dialer interface view
Configure the local end to place
ISDN return calls for the specified
ISDN calling number
Configure a dial string for calling a

The number configured in the dialer number command on the dialer
■
interface is not required to be 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

Configuring ISDN leased line
ISDN leased line can be configured with C-DCC but not RS-DCC. This function is
fulfilled through establishing semi-permanent ISDN MP connections. Such
application requires that a leased line has been established on the PBX of your
telecom service provider and has been connected to the remote device.
