In Akuvox, when you have several monitors added to the same cloud project (either Single Family Home or Community), you can set a sequential call so that, if it is not answered in X seconds, it is redirected between different monitors belonging to the same installation:

However, if the monitors are in different installations, the monitor's web component will be accessed by typing its IP address in a browser. Then, in the Device --> Call Feature --> Call Forward tab, the following settings must be filled in:

-
ACCOUNT: Account 1 (to indicate that it will be between Akuvox devices in different installations)
-
NO ANSWER FORWARD: Enabled (to activate that, if the call is not answered, it will be redirected to another monitor)
-
TARGET NUMBER: SIP (different network) or IP (same network) address of the monitor to which the call will be redirected
-
NO ANSWER RING TIME: How many seconds the monitor will be ringing before the forwarding is done
