•
To disconnect an active call, press down the telephone receiver button
and hold it down at least one second.

If you have any calls on hold, after a few seconds the phone will ring
with a “reminder ring”. Pick up the receiver to reconnect to the call
on hold.
8.4 Retrieving a Call on Hold
•
If you are switching between two calls, simply flash to retrieve the
inactive call.
•
If there is not another active call, then simply hang up the receiver.
After a few seconds the IS425A will signal you with a reminder ring.
This indicates that there is still a call on hold. Pick the receiver up to
connect.
