Solution 3:

Use Circular DCC to implement ISDN caller identification callback.

1Configure 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

2Configure 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 A router and a PC implement PPP callback via the serial interfaces over PSTN. As for DCC 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.
