The version number of the software used in this PBX can be requested
via system telephone (COMfort 1000, 1200 or 2000), a connected sys-
tem display SD-420 (special accessory) or via any internal telephone,
as described here:
The version number is compounded by two digits and one letter (e. g.
1.2b) and is output on the phone with help of four digits:
1st digit: before the comma;
2nd digit: after the comma;
3rd and 4th digit: letter, e.g. a=01, b=02,..., z=26)
Telephones with the correct authorization can activate call forwarding.
The possible problem is that the call forwarding is forgotten later.
If this problem occurs on single telephones, the initializing of the corre-
sponding telephone may help. The connection of the PC may not be
necessary. But consider the possibility that you will probably delete set-
tings that you will have to reconfigure later again.
If the call distribution of incoming external calls does not work as it was
configured first, it is possible that MSN/DDI call forwarding is activated
by individual subscribers. You can switch them all off at the same time.
