Hi Majai,

call-forward noan

To configure call forwarding so that incoming calls to an extension (ephone-dn) that does not answer are forwarded to another number, use the call-forward noan command in ephone-dn or ephone-dn-template configuration mode. To disable call forwarding, use the no form of this command.

call-forward noan target-number timeout seconds

timeout seconds - Sets the duration that a call can ring with no answer before the call is forwarded to the target number. Range is from 3 to 60000. There is no default value.

From this good CME doc;

Hope this helps!

I am only a beginner but in your config try this:

#ephone-dn 701

call-forward noan 705 timeout 4

you might need to save the running-config and reboot the router to bring in the change.
