ISDN caller number callback configuration example
Network requirements
As shown in Figure 56, configure ISDN caller number callback on Router A and Router B by using
traditional DDR, so that when the Router A calls Router B, Router B can make a return call by using an
ISDN caller number.
Figure 56 Network diagram
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.
