Port Mirroring Network Monitoring

The phone now supports the port mirroring network monitoring technique of copying and
sending network packets transmitted as input from a phone port, to another port of a
monitoring device for enhanced analysis and debugging capability.
➢ To enable the feature:
■
Open the phone's 'Modify network' screen ( Settings > Device admin settings > Modify
network ) and touch parameter 'Enable PC Port Mirror' to enable it if it isn't already
enabled.

Manually Performing Recovery Operations

Besides manual recovery options, the Android phones also feature an independent,
automatic problem detection and recovery attempt capability that can culminate in
recovery mode or in switching image slots. Note too that the Android phones also
feature a 'hardware watchdog'. This feature resets the phone if Android is stacked and
doesn't respond (though Android stacking is unlikely); there's no recovery process; the
phone is only reset.
All AudioCodes devices for Microsoft Teams have a reset key or a combination of keys on the
keypad to reset it.
The C450HD / C448HD devices feature a two-key combination to activate each action. To
activate an action, simultaneously press the two keys for three seconds .
While a device is powering up, you can perform recovery operations by long-pressing the
device's reset key / two-key combination.
While long- pressing the reset key / two-key combination, the device's main LED changes color
after every n seconds; each color is aligned with a recovery operation option.
Following are the recovery operation options using the two-key combination on the C450HD
and the C448HD:
■
Enter recovery mode - Long-press the reset key for 4 seconds or simultaneously press the
'back' key + the MENU key; the device's LED lights up red.
■
Switch to the other slot - Long-press the reset key for 10 seconds or simultaneously press
the '4' key + the '6' key; the device's LED lights up green.
■
Enter the device's boot - Long-press the reset key for 15 seconds or simultaneously press
the '1' key + the '3' key; the device's LED lights up blue.
