DETAILED STEPS
Example
The following example sets a timeout of 20 seconds for calls that are transferred to busy destinations:
call-manager-fallback
timeouts busy 20
Configuring the Ringing Timeout Default
The ringing timeout default is the length of time for which a phone can ring with no answer before
returning a disconnect code to the caller. This timeout prevents hung calls received over interfaces such
as Foreign Exchange Office (FXO) that do not have forward-disconnect supervision. It is used only for
extensions that do not have no-answer call forwarding enabled.
