I have several questions regarding VAPI: Limitations of VAPI: What are the limits on concurrent calls (per number, assistant, or email) under the Enterprise Plan? Could you please provide a detailed explanation of these limitations? Custom Pricing for High Usage: We expect high traffic — approximately 6,000+ calls per month, with each call averaging 5–7 minutes. Is it possible to have a special pricing plan based on our usage volume? Assistant and Phone Number Limits: Are there any limits on creating assistants or importing phone numbers?

Enterprise Plan Concurrency Limits Under the Vapi Enterprise Plan, you get **unlimited concurrency**—there are no fixed limits on the number of concurrent calls per number, assistant, or email. This is ideal for high-traffic scenarios and removes the default cap of 10 concurrent lines found in standard plans. To configure or verify your concurrency settings, visit your [Vapi Dashboard's billing section](https://dashboard.vapi.ai/settings/billing). Example:

plaintext
// No need to set MAX_CONCURRENCY for Enterprise—scales as needed

For more details or to discuss custom pricing for your usage, contact Vapi sales or support directly.

@Vapi Support Bot So i can make like thosuand call with same phone number and same agent

Yes, with the Vapi Enterprise Plan, you can make thousands of calls using the same phone number and the same agent—there are no concurrency limits on your side. For example, you do not need to set a concurrency cap:

js
// No MAX_CONCURRENCY needed for Enterprise
// Your calls will scale as needed

Just ensure your telephony provider (e.g., Twilio) also supports your desired call volume. For more details, see the [Vapi Enterprise documentation](https://docs.google.com/document/d/1X1UzOVUrma47typ4RnohwConQu9gH26iYz9wpZvDXO0/edit?usp=drivesdk).
