ii.The matching between the incoming call number and dialer caller is “right end matching”, with “*” representing any character.

iii.If multiple dialer callers match the incoming call number, then select one in line with the following principle:

zMajority principle: first select the one with less “*”.

zMinority principle: first select the one that is found first.

iv. Specify the dialer caller related to an incoming call in line with the following principle:

zIf the physical interface receiving the call is an interface bound by Legacy DDR, then, in “dialer caller” configured by the logic dial interface to which it belongs, search the dialer caller matching the incoming call number.

zIf the physical interface receiving the call is an interface bound by Dialer Profile, then, in all “dialer callers” configured by the logic dial interface to which it belongs, search the dialer caller matching the incoming call number.

v. Before callback, take enable-timeout value configured at the corresponding dial interface (or the physical interface that directly enables DDR) as the delay time.

vi.For an incoming call which is determined as needing callback according to dialer caller, it is also necessary to configure, at the corresponding interface, dialer map completely consistent with dial string and incoming call string (when combining with the dialer string of Dialer Profile, dialer string has to be configured, which needn’t be consistent with the incoming call string).

V.Configure PPP callback

In applying PPP callback, configure one end as Client end and the other end as Server end.

1)The system provides three configuration commands to implement PPP callback Please use the following two commands in the configuration mode of the dial interface.

Table DC-1-26PPP callback commands in the configuration mode of the dial interface

Operation	Command
Set the local end as callback Server end/Client end	ppp callback accept request
Configure callback by searching the matching dialer map	dialer callback-server username
according to the name of the remote end or by the callback dial
string. At this time, dialer map command must contain name	or dialer callback-server dial-string
parameter, otherwise callback is impossible

The first command is configured at Server end, used by DDR to determine whether to call back by using the dial string provided PPP, or to call back according to the configuration contents of dialer map.

The key word “accept” in the second command sets the router as Server end and the key word “request” sets the router as Client end.

Please use the following command in global configuration mode.

Operation	Command
The call string for the local end to determine callback	user name [callback-dialstring telephone-number]
according to the name of the remote end
