# Can I purchase additional Concurrency or CPS?

> Upgrade your Vobiz concurrency and CPS limits through the dashboard to scale outbound campaigns and handle thousands of simultaneous calls - step-by-step instructions.

**Yes.** Once your account has completed regulatory verification, your base provisioning limits provide a stable starting baseline. As your call volume grows, you will likely need to increase your operational capacity.

## How to request an upgrade

Vobiz provides dynamic scaling for both concurrent channels and CPS limits to support thousands of concurrent calls.

<Steps>
  <Step title="Sign in to the dashboard">
    Log into the **Vobiz Dashboard**.
  </Step>

  <Step title="Open Limits & Quotas">
    Navigate to **Settings** and select the **Limits & Quotas** tab to view your current capacities.
  </Step>

  <Step title="Confirm billing setup">
    Ensure you have sufficient prepaid balance or a post-paid billing arrangement in place. Limit modifications may require a nominal recurring or one-time provisioning fee depending on the requested volume.
  </Step>

  <Step title="Request an increase">
    Click the **Request Increase** button, specify whether you need higher Concurrency or CPS (or both), and our network team will provision it.
  </Step>
</Steps>

<Note>
  **Enterprise Scaling** - For extremely high-volume dialers requiring multi-thousand channels or more than 10 CPS consistently, please [contact our enterprise support team](/faq/contact-support) directly to establish dedicated SIP trunks and specialized routing geometries.
