Limits

Concurrent call limits

Each account has a maximum number of simultaneous active calls. Your current limit is displayed in the account dashboard.

Rate limiting

A maximum calls-per-minute rate limit prevents abuse. If you exceed the rate limit, new call requests are rejected until the rate drops.

Priority queue

When you hit your concurrent call limit, new calls don't fail immediately — they enter a priority queue.

How priority is determined

• Account tier — higher-tier accounts get higher base priority
• Age bonus — the longer a call waits in the queue, the higher its priority climbs. This prevents starvation so no call waits indefinitely.

Queue behavior

• When a running call ends, the highest-priority queued call starts next
• The queue has a maximum depth — if the queue is full, new calls are rejected
• Queue position and estimated wait are not currently exposed in the UI
