the 2 central pins (number 2 and 3) are typically used:

RJ 11
LINE & TEL-SET
CONNECTOR PIN-OUT
This module allows the connection on parallel to the Telephone Line of a standard telephone set (for example for dialling
purpose). Please note that „Tel Set‟ socket is always active (i.e. it doesn‟t depend on the „Hook‟ button state) and it has
the same Pin-Out as the LINE socket.
The telephone hybrid interface is powered by the same power flowing also into the external
telephone set. In the event You will experience some lack in the audio performance or in the
telephone hybrid operation (no Ring, no Hook, etc), try to disconnect the Telephone Set itself.
Should the device be put out of action due to being struck by lightning or excess voltage, disconnect
it from the telephone line without delay. Do not reconnect until the device has been checked. If in
doubt contact the technical support service.
Make sure there is suitable lightning protection to protect the device.
Alternatively you should disconnect all connectors from the device during a storm or when the device
is going to be unsupervised or not used for a longer period of time. These measures will protect
against damage by lightning or excess voltage.
