There have been reports of rain affecting the sensitivity of the keypad and it results in phantom calls occurring. There are recommended steps as per below and not all may be required. Note that these may modify functionality somewhat.

Beta firmware 912.30.12.107 (or later) should be installed: https://e-fw-device-upgrade.oss-eu-west-1.aliyuncs.com/6500/912.30.12.107.rom

There are various setting options under the web interface:

-Enable “Activation by Motion Detection” which changes the behaviour of the intercom waking up. It's under the Device > LCD > Wake Up Mode section. This will prevent the keypad from activating without someone being in front of the intercom. You do then need to swipe to unlock.

-There is a 'Keypad Splash Protect' option which is typically enabled by default, ensure it is so. Within the Akuvox Web Interface adding /#/8848 to the URL shows a new page. It's then available under Status > Info of the web interface. 

-Disable the bell icon as speed dial which is under Intercom -> Basic -> Manager Dial.
The manager dial section is what is called via the speed dial. Then it is set up for button calling here: https://knowledge.akuvox.com/docs/screen-display-configuration-2
It is suggested to disable the speed dial.



-In the web interface under section 'Device -> Keypad', set keypad to 'PIN Entry' only.
