The use of voip mode is well established technique for building encrypted messaging apps on iOS, and its unsurprising that whatsapp is built around it, especially when you consider that whatsapp is a voip app. No conspiracy theories are necessary.
- tareqak 7y agoAre Signal and other messaging apps relying on this feature and do they offer VoIP functionality?
- makomk 7y agoAs far as I can tell, that's a yes to both: Signal supports VoIP calls, they're definitely using the PushKit VoIP API, and I assume they're using that API for both text notifications and calls since the code doesn't have any reference to the other API they could use.
