Could this violate Signal's security model?
Your country would be able to determine exactly with whom you're speaking by nature of IP's being public.
It's arguably more difficult if there's a server intermediary, especially when speaking to someone in a different country.
Unless things have changed, calls on signal between you and people on your contact list are p2p. This is necessary to have a call experience like what people are used to. The latency of going through a relay makes conversation more difficult. Yes that does mean that someone on the network can see that there is a signal call between the 2 ip addresses (but they wouldn't know the identities of the users) https://signal.org/blog/signal-video-calls/
Ah, alright. Fair enough.
Though in that case my earlier assumption about AWS doesn't hold true either.
Signal has the option to relay calls, but it is off by default.
