Solution 3:
Use Circular DCC to implement ISDN caller identification callback.
1 Configure RouterA:
[Router] dialer-rule 1 ip permit
[Router] interface bri 0
[Router-Bri0] ip address 100.1.1.1 255.255.255.0
[Router-Bri0] dialer-group 1
[Router-Bri0] dialer route ip 100.1.1.2 user usera 8810152
2 Configure RouterB:
[Router] dialer-rule 2 ip permit
[Router] interface bri 1
[Router-Bri1] ip address 100.1.1.2 255.255.255.0
[Router-Bri1] dialer-group 2
[Router-Bri1] dialer route ip 100.1.1.1 user usera 8810148
[Router-Bri1] dialer call-in 8810148 callback
Router-to-PC Callback
for DCC
A router and a PC implement PPP callback via the serial interfaces over PSTN. As
shown in the following figure, the PC and RouterA are interconnected via the
modems across PSTN. Circular DCC is adopted in this case. The PC is specified to
be the callback client whereas RouterA to be the callback server. They implement
callback according to the configuration of the
dialer route command. RouterA
uses the address 100.1.1.1 and the PC accepts the address assigned by RouterA.
