The default dialer idle-timeout period is 120 seconds. So if there is no
traffic for a 120 second period, the call will disconnect.
You can increase/decrease using "dialer idle-timeout xx" under the bri
interface or dialer interface.
However, you should want the call to disconnect when there is no traffic to
avoid accumulating large ISDN bills from the provider.

Subject: Solie lab 16-pg 536--backup interface using ISDN
Good Evening,
I am having issues working this lab where item 5 states "both routers
must be capable of initiating ISDN calls" . Solie's solution places the
backup interface cmd on both routers' serial interface. On my lab, this
brings both sides into a standby state and neither will call the other.
When removing the backup interface cmd off one router, backup works well
except the B channels start to disconnect on the called router after the
120 second timeout.
Is Solie incorrect on this config? If not, can someone tell me what I
am doing wrong?
Below is the config where R1 will call R2; however, R2 disconnects the
call after 120 seconds:
R1-Greenbay
interface BRI0
ip address 170.20.20.1 255.255.255.252
