Understanding LeadConnector Inbound Call Rate Limits

Modified on: Tue, 20 May, 2025 at 11:23 PM

To maintain the reliability and performance of our voice infrastructure, LeadConnector enforces inbound call rate limits across different types of phone numbers. These safeguards are essential to prevent spam, abuse, and system overloads, ensuring a high-quality experience for all users.

This article outlines how rate limits work for IVR-connected numbers, Voice AI-connected numbers, and regular numbers.

1. IVR-Connected Numbers

No restrictions apply.
These numbers are designed to handle high volumes and are not subject to inbound call rate limiting.

2. Voice AI-Connected Numbers

Voice AI numbers are designed for intelligent call handling through automation. Due to their potential for high concurrency, they are subject to stricter rate controls.

? Violations and Limits:

Condition	Threshold	Result
From a number:	>200 calls per minute	1 violation (current call is blocked)
To a number:	>200 calls per minute	1 violation (current call is blocked)
Violation cap:	>5 violations per hour	All inbound calls for the account are blocked

3. Regular Numbers

Standard phone numbers (not connected to IVR or Voice AI) have more conservative rate limits to avoid potential misuse or system degradation.

? Violations and Limits:

Condition	Threshold	Result
From a number:	>10 calls per minute	1 violation (current call is blocked)
To a number:	>15 calls per minute	1 violation (current call is blocked)
Violation cap:	>5 violations per hour	All inbound calls for the account are blocked

What Happens When the Violation Cap is Reached?

If your account incurs more than 5 violations within an hour, all inbound calls will be permanently blocked for both Voice AI and regular numbers. To restore access, Please contact GHL support for assistance.

Best Practices to Avoid Rate Limits

Use IVR for High Volume: If you anticipate heavy inbound traffic, connect your numbers to an IVR system where possible.
Distribute Call Volume: Avoid routing excessive traffic through a single number. Use multiple numbers to balance load.
