I knew when I signed up for RW originally that our voice calls over wifi are just plain unencrypted SIP calls. I’m still a fan of RW’s philosophy and plan structure, but now that many carriers are offering WiFi calling (using various different underlying implementations) are there any updates available on whether there are plans to introduce encryption to RW WiFi calls? I know there’s been some talks about VPNs but AFAIK this can also be implemented via TLS without having to route everything through a VPN.
I think encryption is becoming more and more crucial to online communication and I hope that as the tech evolves RW will consider improving security on voice calls this way. Last time I did any reading about it, it seemed like eavesdropping on a plain SIP call is trivial for anyone with network access, which can be a point of concern for people making calls while on work networks, for instance, along with the general internet.
