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 telephone, this function recognizes when
this conversation is ended. Your telephone then rings.
When you pick up your handset, the number of the desired
party is automatically 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.
Call-back requests can also be deleted manually, with the
oldest callback request being deleted first.
