Signal is GOOD but you must still trust the operators of the service and their servers which are not open source.

A BETTER way is to operate your own server (e.g., Asterisk) and connect to users only via IPv6 (ideally using cjdns https://github.com/cjdelisle/cjdns/blob/master/doc/projectGoals.md this prevents man-in-the-middle attacks.

Cjdns guarantees confidentiality, authenticity and integrity of data by using modern cryptography in a non-intrusive way. Information transmitted over a cjdns network can’t be altered or read en-route. While you can create multiple identities, it’s practically impossible to impersonate other nodes on the network and since a node’s IPv6 address is the fingerprint of its key, man-in-the-middle attacks are not possible.

Flexible and secure SIP https://en.wikipedia.org/wiki/Session_Initiation_Protocol clients supporting IPv6, such as Linphone, are cross platform.

BEST is to use direct SIP p2p IPv6 connections (no server) and cjdns.
