System functions and features as of R4.1
syd-0570/1.2 – R4.1 – 08.2016
• If a user who is in a user group along with other users rejects a call, the other users
continue to ring (unless Default call forwarding if rejected is configured, see section
below). If all the UG members reject the call, the call set-up is cleared down and the
calling user obtains the busy tone.
• For each user a Default call forwarded if rejected can be configured separately for
internal and external calls. Possible redirection destinations include internal or ex-
ternal users, PISN users, abbreviated dialling numbers, user groups, CDE call num-
bers, etc. This means the response if the call is rejected can vary according to the
call’s origin, e.g. voice mail for internal calls and transfer for external calls (see "De-
fault call forwarding per user", page 178).
