Hey TP-LINK !! Why VoWiFi disappeared from my phone when my Deco in Router Mode but working fine in AP Mode so do i need to change anything? SIP ALG or any DNS Server? Please suggest me.

@brumbies You can update to 1.8.0 beta firmware.

@Lilyinthevalley Still not available on may routers and mesh systems.

@Lilyinthevalley No these channels are not allowed in Europe region.

@Lilyinthevalley What's your deco region code? EU or US ?

@Boeau I think all the issues are related to subnet mask because some IoT devices and phones could'nt support 255.255.252.0 subnet mask so you can change it to 255.255.255.0 because newer deco models...
