Let me tell you something...
With 3CX Voip system and DIDWW you can have a virtual VoIP & fax server with virtual numbers (from DIDWW) and booom you have a "nostr relay" based on fax and secure E2E encryption.
You can send notes and memes over fax. 3CX also can fw those faxes attached to an email, run by a simple local email server (can be the same machine).
I've built this system several times in the past... works super nice.
NOBODY can intercept or read those messages over fax.
