Why I Own My Telecom Stack Instead of Paying $200/Month for VoIP SaaS

Business phone systems are a tax on not knowing how VoIP works.

I stopped paying it.

What the Market Charges

• Grasshopper: $49/month for 1 number, 3 extensions
• RingCentral: $99/month per user
• Dialpad: $75/month per user
• Google Voice for Business: $30/month per user

For six business lines with AI voice agents, I would spend $200 to $500 every month depending on the plan.

What I Actually Pay

$29.70 per month. Six lines. AI on every one.

Breakdown:

• VoIP.ms DIDs: 6 x $4.95 = $29.70/month
• Asterisk: free, runs on a VPS I already own
• VAPI: usage-based, low volume in early stage

What I Own vs What I Rent

With SaaS I rent access. If they raise prices, change terms, or shut down, I lose the system.

With Asterisk + VoIP.ms I own the PBX configuration, own the SIP trunk relationship, and can move providers without rebuilding anything.

The Infrastructure Sovereignty Principle

I apply five rules to every service in my stack:

1. Multi-model abstracted — no single vendor lock-in
2. Logged to Supabase in real time
3. Self-hosted equivalent exists for every managed service
4. Contingency defined before going live
5. All data, prompts, and outputs are mine

Telecom is not special. The same logic applies. Own the stack or pay the tax forever.

Is It Hard?

Asterisk has a learning curve. VoIP.ms requires KYC. PJSIP configuration takes a few hours to get right.

After that, it runs without touching it. That is the trade. A few hard hours once, or $200 every month forever.
