Statement introduced in Junos OS Release 7.5.
On J Series Services Routers with interfaces configured for ISDN with callback, specify the amount of time the dialer waits before calling back the caller. The default wait time is 5 seconds. The wait time is necessary because, when a call is rejected, the switch waits for up to 4 seconds on point-to-multipoint connections to ensure no other device accepts the call before sending the DISCONNECT message to the originator of the call. However, the default time of 5 seconds may not be sufficient for different switches or may not be needed on point-to-point connections.
To configure callback mode, include the callback statement at the [edit interfaces dln unit logical-unit-number dialer-options] hierarchy level.
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.
