• If a route is used to make an attempt to switch a call and the call can be suc-
cessfully signalled to the called terminal (terminal responds with an
Alerting
message) and if a value greater than
0
has been entered in the
Timeout
field for this route, then a search will be made for a further route, if the call is
not accepted within the specified number of seconds. This corresponds to the
“Call forwarding no response (
CFNR
)” function. If you enter a
Timeout
of
more than 120 seconds, this timeout will have no effect since the global time-
out for setting up the call will expire first. Since, if timeout is entered, availa-
ble alternative routes will always be tried, after a failed call, it has the same
effect as the “Call forwarding busy” (
CFB
) function.

Check the
Final
box in the
Map
entry if, after attempting to switch a call using a
map entry, you want to prevent further routes from being tried out.
You can likewise check the
Final
box in the
Map
entries for a route with destina-
tion
MAP
. In this case, no further
MAP
entries will be evaluated but a search will
still be made for other appropriate routes.
