[WP7609] How to customize the firmware for modified HW

[hkshanhai]

@WP7609 VoLTE supported SKUs

So generically speaking all of the current WP76 SKU’s now do support VoLTE, 18 months ago this was not the case and we have updated them over time. Regards Matt

OK, thanks. If so, I think the 2019 WP7609 I bought supports VoLTE
