Fanvil X6u not applying DST Perth +8 Western Australia

[Scott Maddocks]

We've recently rolled out 16 Fanvil x6u phones and are currently unable to resolve the DST issue with the Fanvil template. All phones are an hour out.

3CX Version: 16.0.930
3CX Hosted: Amazon Lightsail
IP Phone Model: Fanvil x6u (2.2.11)
Provisioning via SBC (16.2.24)
Default Fanvil Template
Passed Firewall Checker

Global Timezone set to +8 Australia (Perth)
Extension > Phone Provisioning > Timezone set to +8 Australia (Perth)
Settings Parameter Settings DST Option set to 0

On the Default Tempalte Config of the phones under the VOIP_CONFIG_FILE

{IF ua=Fanvil X1,Fanvil X2C,Fanvil X2,Fanvil X3S,Fanvil X4,Fanvil X1S,Fanvil X1SG,Fanvil X3U,Fanvil X3SG,Fanvil X4U,Fanvil X5U,Fanvil X6U,Fanvil X5S,Fanvil X6,Fanvil X7,Fanvil X7C,Fanvil X210,Fanvil X7A}
<Time_Zone>%%timezonex3s%%</Time_Zone>
<Time_Zone_Name>%%timezonenamex3s%%</Time_Zone_Name>
<Location>%%locationx3s%%</Location>
<Enable_DST>%%dstx3s%%</Enable_DST>
<DST_Type>%%dstx3s%%</DST_Type>
{ENDIF}

On Custom Template Config - If i change to the below

{IF ua=Fanvil X1,Fanvil X2C,Fanvil X2,Fanvil X3S,Fanvil X4,Fanvil X1S,Fanvil X1SG,Fanvil X3U,Fanvil X3SG,Fanvil X4U,Fanvil X5U,Fanvil X6U,Fanvil X5S,Fanvil X6,Fanvil X7,Fanvil X7C,Fanvil X210,Fanvil X7A}
<Time_Zone>%%timezonex3s%%</Time_Zone>
<Time_Zone_Name>%%timezonenamex3s%%</Time_Zone_Name>
<Location>%%locationx3s%%</Location>
<Enable_DST>0</Enable_DST>
<DST_Type>0</DST_Type>
{ENDIF}


it works however the phones come up red saying unsupported. We've reverted back to the default fanvil template.

We've manually had to log into each phone and apply the DST change. Once we've applied the change time is fixed, however when the phones reboot it resets the setting.

Anyone got any recommendations?
