You now have various options for handling the two subscribers (alternation, confer-
ence). If you want to transfer the call waiting party that you have taken, you must first com-
plete your conversation with the first calling partner.
Instead of pick-up, you can also complete your current conversation by replacing the
handset. After this, initiate the other conversation in the normal way by lifting the handset.

If the door function is also set on relay no. 3 (with ETS-4308 I only – default setting),
it is switched on at the same time as the door opener relay for 1-99 minutes. This means
that it is used, for example, to automatically switch on and off staircase lighting.
When querying a door extension, door opening is not possible with ISDN telephones.
To be able to open the door, the telephone set must have door opener permission granted
(default setting/see also user program).
