ISDN caller number callback configuration example

Network requirements
As shown in
traditional DDR. Then, Router B can make a return call by using an ISDN caller number when Router A
calls Router B.

NOTE:
Make sure the stored program controlled switch (SPCS) in the ISDN network supports sending ISDN
calling numbers.
Configuration procedure
1. Configure Router A:
# Create dialer group 1 and configure a dial rule for it.
<RouterA> system-view
[RouterA] dialer-group 1 rule ip permit
# Configure an IP address for interface BRI 2/4/0.
[RouterA] interface bri 2/4/0
[RouterA-Bri2/4/0] ip address 100.1.1.1 255.255.255.0
# Enable traditional DDR on the interface.
[RouterA-Bri2/4/0] dialer circular enable
# Associate the interface with dialer group 1.
[RouterA-Bri2/4/0] dialer-group 1
# Configure the dial string for calling Router B.
[RouterA-Bri2/4/0] dialer route ip 100.1.1.2 8810052
# Set the holddown timer to 15 seconds.
[RouterA-Bri2/4/0] dialer timer enable 15
# Configure BRI 2/4/0 to carry ISDN calling number 8810048 in the message sent to the called
party.
[RouterA-Bri2/4/0] isdn calling 8810048
