Adding a timeout
You can specify a timeout during which call forwarding is
not active (i.e., call forwarding does not take effect until
this number of seconds has passed after the phone receives
the call attempt). To do this, adding an asterisk (*) and the
time period in seconds to the codes listed above.
Example: You want to forward fax calls to 972-555-1111
when not able to take calls, but let 25 seconds
pass first.
