Split traffic between agent versions to test performance. Routing is deterministic by caller number (SHA256 hash) — the same caller always gets the same variant.

​
Set Weights

Weights must sum to 100: 
curl -X PUT http://localhost:8090/v1/phone-numbers/PHONE_ID/routing \
  -H "Authorization: Bearer tc_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "weights": [
      {"agent_id": "agent-v1-uuid", "weight": 80},
      {"agent_id": "agent-v2-uuid", "weight": 20}
    ]
  }'

​
Check Routing

curl http://localhost:8090/v1/phone-numbers/PHONE_ID/routing \
  -H "Authorization: Bearer tc_xxx"
Response: 
{"mode": "weighted", "weights": [...]}

​
Clear Test

Revert to single-agent routing: 
curl -X DELETE http://localhost:8090/v1/phone-numbers/PHONE_ID/routing \
  -H "Authorization: Bearer tc_xxx"

How It Works

  1. Inbound call arrives on a phone number with weighted routing
  2. TurnCall hashes the caller’s phone number (SHA256)
  3. The hash determines which agent variant handles the call
  4. Same caller always gets the same variant (deterministic)
