Reliability & call limits
Uptime, concurrency, and what happens when things go wrong.

Uptime & reliability
Sancharya's calling infrastructure is built on LiveKit's global WebRTC network with automatic failover. We target 99.9% uptime for call connectivity. If a call fails to connect, the system retries automatically before marking it as failed.
Concurrency limits
Each account has a default concurrency limit — the maximum number of simultaneous live calls across all employees. This limit scales with your usage history and can be increased on request.
If you're running a large Bulk campaign and hit your concurrency limit, calls are queued (not dropped) and dialed as slots free up.
API rate limits
The webhook and REST API endpoints are rate-limited to prevent abuse. Standard limits are 60 requests per minute per API key. If you need higher limits for high-volume integrations, contact us.
