UponAI enforces constraints to ensure smooth operation and prevent misuse. These limits can be adjusted based on your needs on a case-by-case basis.

​
Concurrency

Concurrency refers to the number of simultaneous active voice calls your system handles at any moment. For example, 15 users on calls at the same time = 15 concurrent calls. Pay-As-You-Go users receive a quota of 20 concurrent calls. To increase your limit, go to the Billing page to upgrade your plan.
You don’t need to create multiple agents to manage multiple concurrent calls. Each agent can handle an unlimited number of calls as long as the total stays within your concurrency quota.
You can check your current concurrent call count in the dashboard.

​
Concurrency Burst

Concurrency Burst lets you temporarily exceed your standard concurrency limit during peak demand. Calls that would normally be rejected will proceed with an additional surcharge.

​
How It Works

Call TypeCost
Within standard limitNo additional charge
Above standard limit (burst)+$0.10/min for the entire call duration
The burst surcharge applies to the entire duration of any call that started while in burst mode — not just the portion above your normal limit.

​
Burst Limit Calculation

Your burst limit is the lower of:
  • 3× your concurrency limit, OR
  • Your concurrency limit + 300
Examples:
  • Limit of 50 → burst up to 150 (3 × 50)
  • Limit of 200 → burst up to 500 (200 + 300, since 200 + 300 < 3 × 200)

​
Enable Concurrency Burst

Go to Settings > Limits in your dashboard to enable or disable concurrency burst. Best for:
  • Unpredictable traffic spikes
  • Campaign launches with higher-than-normal call volumes
  • Seasonal peaks without permanently upgrading your plan
If you consistently exceed your normal limit, upgrading your base concurrency allocation is more cost-efficient.

​
Max Call Duration

Calls end automatically after 1 hour by default. You can increase this up to 2 hours in your agent settings. For calls longer than 2 hours, contact support at support@uponai.com.

​
Max Prompt Token Length

The maximum prompt length when using the UponAI LLM framework is 32,768 tokens by default. Prompts exceeding this limit will be rejected when creating or updating the LLM.
Prompts over 3,500 tokens incur additional charges. For longer context requirements, contact support at support@uponai.com.
