Change call forwarding relation
CHCALF: <CF-TYPE>,[<ORIG-BSP-ID>sr][[,[<DEST-NUMBER>]]
[,[<UNIT>]][,[<CFDA-TIME>][,<CALL-ORIG-TYPE>]]];
If DEST-NUMBER is omitted, the call forwarding relation of the originator will
be erased.
Depending on the CF-TYPE, the originator should be a BSP-ID or a UNIT:
| CF-TYPE | ORIG-BSP-ID | UNIT |
|----------------+------------------------+-----------|
| 0, 1 and 8 | extension BSP-ID | - |
| 2 and 3 | group DNR (All groups) | - |
| 4 and 5 | ACD group DNR | - |
| 6, 7, 9 and 10 | - | UNIT |
For CF-TYPE 6, 7, 9 and 10 UNIT might only be omitted in a single unit system.
Layout for CF-TYPE = 0:
CHCALF: <CF-TYPE>,<ORIG-BSP-ID>sr[,<DEST-NUMBER>
[,,[<CFDA-TIME>][,[<CALL-ORIG-TYPE>]]];
Layout for CF-TYPE = 1..5 and 8:
CHCALF: <CF-TYPE>,<ORIG-BSP-ID>sr[,<DEST-NUMBER>][,,,[<CALL-ORIG-TYPE>]];
Layout for CF-TYPE = 6, 7, 9 and 10:
CHCALF: <CF-TYPE>,,[<DEST-NUMBER>],<UNIT>[,,[<CALL-ORIG-TYPE>]];
