Need this done for your project?
We implement, you ship. Async, documented, done in days.
Choosing the right server
Mumble: low-latency group voice, optimized for clarity, used by gaming and security communities. SIP+ZRTP: standard telephony protocol with E2EE addon, interoperable with many clients. Asterisk: full PBX, useful for organizations that need DID numbers and call routing.
Sizing
Mumble for 100 simultaneous users: 2 vCPU 2 GB RAM. SIP server for small org: similar. Asterisk PBX with 50 extensions: 4 vCPU 8 GB RAM. Bandwidth is generally not the binding constraint at small scales.
Anubiz binding
Anubiz offshore VPS plans from $17.90/mo. Choose locations close to your users for latency - Romania for Europe, Netherlands for Western Europe, Iceland for political resilience over latency. Crypto payment, no KYC. Internal links: /en/hosting-for-jitsi-meet-offshore, /en/hosting-for-bigbluebutton-offshore, /en/hosting-for-activist-secure-comms-stack.
Telephony bridging
If you bridge to the PSTN (DID numbers, outbound calling) you need a SIP trunk provider - that is a separate service. Anubiz hosts the VPS; the PSTN side is your relationship with a trunk provider. Many trunk providers accept crypto.
