Caution
If you enable the Recorder , the call is answered and recorded via 1
device only . If you set the Recorder for two or more devices in one LAN
or called group, the call is answered and recorded via the device that
was the first to pick up the call (if the same Recorder activation timeout
is set for all the devices), or via the device that is assigned the lowest
Recorder activation timeout . In heavy-traffic networks, there may be a
delay during call setups and so it cannot be guaranteed that the call will
be picked up and recorded by one and the same device.
