Is it possible to do the following?
When R6 loses route to 5.0.0.0, dialer watch causes R6 to Dial R5.
R6 & R5 are configured for callback. When R6 calls R5, R5 should disconnect the call and return the call to R6.
Please refer to the configs below. Callback works on its own. Dialer watch works on its own. Put them together, and you get problems.
R6 calls R5. R5 disconnects call, and prepares to call back. Meanwhile, dialer watch on R6 causes R6 to establish a new call straight after the original call is disconnected by R5.
Are there some timers to cause dialer watch on R6 to wait for a specified time, before dialling again (so that it can receive the callback from R5)?
