Statement introduced in Junos OS Release 7.5.
On J Series Services Routers with interfaces configured for ISDN, configure the dialer to terminate the incoming call and call back the originator after the callback wait period. The default wait time is 5 seconds. To configure the wait time, include the callback-wait-period statement at the [edit interfaces dl n unit logical-unit-number dialer-options] hierarchy level.
The incoming-map statement is mandatory for the router to accept any incoming ISDN calls.
If the callback statement is configured, you cannot use the caller caller-id statement at the [edit interfaces dln unit logical-unit-number dialer-options] hierarchy level.
