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:
z Majority principle: first select the one with less “*”.
z Minority principle: first select the one that is found first.
iv. Specify the dialer caller related to an incoming call in line with the follo wing principle:
z If 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 belon gs,
search the dialer caller matching the incoming call number.
z If 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 correspond ing dial
interface (or the physical interface that directly enables DDR) as the dela y time.
vi. For an incoming call which is determined as needing ca llback according to dialer
caller, it is also necessary to configure, at the corresponding interface, dialer map
completely consistent with dial string and incoming c all 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 ca llback
Please use the following two commands in the configuration mode of the d ial interface.
Table DC-1-26 PPP 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
according to the name of the remote end or by the callback dial
string. At this time, dialer map command must contain name
parameter, otherwise callback is impossible
dialer callback-server username
or dialer callback-server dial-string
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 Ser ver 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
according to the name of the remote end user name [callback-dialstring telephone-number]
