VoLTE/VoWiFi Research (opens in new tab)

This looks to be a follow up of:

Which was a really good read!

I noted this however:

> However, VoLTE’s implementation is not compatible with our everyday VPNs and VoIP software. This report from Sysmocom shows that it would take months to modify Ubuntu Touch for VoLTE support.

I wonder why that is? I am using a Pinephone with Mobian right now, and a Librem 5 with PureOS, and both support VoLTE just fine.

So I could setup my own mini-carrier with a VOIP backbone? Seems cool

This is really interesting! Thanks for sharing!
