Shared control plane
Org → billing account → project / subaccount → resource. Credentials, inventory, quotas, routing policy.
Communications platform · control plane
The operational layer for sending a message.
Meridian is not a REST wrapper. It is the tenant, inventory, routing, metering, compliance, and webhook fabric that a CPaaS actually runs on — with a native API and a Twilio compatibility gateway that translates, never clones.

Independent data planes
Messaging, Voice/SIP, Verify. Separate lifecycles. Same tenant and meter.
Least-cost routing
Score = wq·Q − wc·Ĉ − wl·L − wf·F + wp·P. Direct + aggregator paths per market.
Translation gateway
Parser → canonical command → native service → serializer. /2010-04-01 is a skin.
MVP surface
What the first market has to ship.
Video, Conversations, Email, and Fax stay out of scope. Everything below is live in this console as an operational simulation — SIDs, DLR, usage events, and all.
- SMS lifecycle + GSM/UCS-2
- Messaging Services + sticky sender
- Phone numbers + porting
- Voice Call / Call Leg + TwiML
- SIP trunks, CPS, IP ACL
- Verify as orchestration
- Webhooks HMAC + X-Twilio-Signature
- Usage → rate → invoice
- Prepaid / postpaid limits
- Regulatory bundles
- Fraud velocity + geo
- Sandbox virtual carrier
Aether Logistics is already on it.
Three projects, Israeli and US numbers, Partner / Cellcom / Bandwidth routes, a Hebrew UCS-2 dispatch, and a STOP on the inbound desk.
