Enterprise – 1.000-min OUTBOUND demo (Colombia) → Scale to LATAM/EU | Full plan catalog, Concurrency

Hi Vapi team, We’re planning a 1,000-minute outbound demo in Colombia focused on sales. If results are positive, we will also enable inbound and scale with a Colombian telco across LATAM and selected EU countries. Choosing the right telecom infrastructure (SIP trunking, numbering, regions) and the right automation/orchestration stack is critical for us given the potential scale (thousands of concurrent calls). We’d appreciate concrete recommendations and any reference architectures you can share. Could you please share: Your full catalog of plans (not only PAYG/Business/Enterprise), with concurrency/CPS, rate limits, SLA, regions and support tiers. Pricing by component and volume discounts (Colombia now; later LATAM/EU), for OUTBOUND and INBOUND. Audio/transcript retention by plan (defaults, configurability, deletion/export/streaming options). Connectivity & cost/latency trade-offs (direct SIP trunk with a local carrier vs PSTN/Twilio) and BYOK (ASR/TTS/LLM). Latency benchmarks (ASR→LLM→TTS) and recommended regions/codecs for Colombia and future LATAM/EU rollouts. Outbound specifics (CPS, answering machine detection, number reputation/warm-up) and Inbound features (IVR, queues, transfers). Professional services/consulting for architecture and load testing. We would appreciate your response at your earliest convenience. Thank you!

To set up a high-concurrency outbound demo, use Vapi's batch calling API with scheduling. Here’s a sample payload for scheduling multiple outbound calls with concurrency: 
{
  "assistantId": "your-assistant-id",
  "phoneNumberId": "your-phone-number-id",
  "customers": [
    { "number": "+573001234567" },
    { "number": "+573001234568" }
  ],
  "schedulePlan": { "earliestAt": "2025-10-10T14:00:00Z" }
}
{
  "assistantId": "your-assistant-id",
  "phoneNumberId": "your-phone-number-id",
  "customers": [
    { "number": "+573001234567" },
    { "number": "+573001234568" }
  ],
  "schedulePlan": { "earliestAt": "2025-10-10T14:00:00Z" }
}
This approach lets you efficiently launch concurrent calls for your demo. For unlimited concurrency and higher rate limits, consider the Enterprise plan, which also includes technical support and SLA commitments. More details: Vapi Enterprise. Sources: - Vapi Enterprise - Outbound Calling
