Call Back on No Response (CCNR) on the ISDN Line
The “Call Back on No Response” function can be used when
you dial a number and the party does not respond. Once
the party can be reached again and conducts a call from her
or his phone, this function recognizes when this conversa-
tion is ended. Your phone then rings. When you pick up
your handset, the number of the desired party is automati-
cally dialed again.
“Call Back on No Response” can be used both for external
and internal connections.
This command can be activated five times for each line.
