Versatile Routing Platform

DDR Configuration

zGeneral support (both ends have fixed network layer addresses and have implemented RFC1570).

zSupport when Client end needs dynamic distribution of network layer addresses.

zSupport when only Server end has implemented RFC1570.

2)In ISDN environment, use ISDN calling line identification function to realize callback.

IV. Configure ISDN calling line identification callback

To support ISDN calling line identification callback, a dialer caller command is provided at ISDN interface.

1)The configurations when ISDN calling line identification callback is combined with Legacy DDR.

Table DC-1-24Use Legacy DDR to configure ISDN calling line identification callback

Operation

Command

 

 

Enter the configuration mode of the designated dial

interface interface-type interface-number

interface (used in global configuration mode)

 

Perform callback or connection for an incoming call that

dialer caller remote-numbercallback

matches remote-number (used in the configuration mode

or dialer caller remote-number

of the dial interface)

 

Set delay time before callback (used in the configuration

dialer enable-timeout seconds

mode of the dial interface)

 

remote-numberin dialer caller command refers to the telephone number of the remote end.

2)The configurations when ISDN calling line identification callback is combined with Dialer Profile.

Table DC-1-25Use Dialer Profile to configure ISDN calling line identification callback

Operation

 

Command

 

 

 

Enter the configuration mode of the logic dial interface

interface dialer

interface-number

(used in global configuration mode)

 

 

Perform callback or connection for an incoming call that

dialer caller remote-numbercallback

matches remote-number (used in the configuration mode

or dialer caller remote-number

of the dial interface)

 

 

Set delay time before callback (used in the configuration

dialer enable-timeout seconds

mode of the dial interface)

 

 

3)Application features of ISDN calling line identification callback

i. An incoming call is processed in any of the following three ways based on the matching of incoming call number and the locally configured dialer caller:

zReject the incoming call—if dialer caller has been configured and the incoming call number doesn’t have any matching dialer caller.

zAccept the incoming call—dialer caller has not been configured, or the incoming call number matches the dialer caller without the key word “callback”.

zCallback—the incoming call number matches the dialer caller containing the key word “callback”.
