5.8.3 CFNR – Call Forwarding No Reply

This service works in the same way like CFU, but redirection only takes place when
nobody answers the phone and your telephone is already ringing for about
20 seconds (depends on your provider). You can use this service just like CFU, but it
offers you the opportunity to answer when you are at home.

Keep in mind that after activation of CFU no call will be put through to you
anymore.

5.8.4 Call Forwarding control Interrogation

In principle, it is possible to select several Call Forwarding services for MSN1 (e.g.
CFNR + CFB). The signalling, however, indicates only one existing Call Forwarding
function. Besides, an eventual replacement of the NT1+2a/b, a reset or a mal-
function may result in certain inconsistencies within the Call Forwarding data. This is
the reason why an inquiry of the Call Forwarding procedure has been implemented.
