Regulatory Requirements

The configuration of US long codes or US/CA toll free numbers will only work for fully registered numbers.

 
Aircall only allow domestic sending, with the exception of messages between US and Canada — same as the behavior described for messaging directly from Aircall applications.

Rate Limits

Aircall API limits the number of requests to 60 per minute regardless of the endpoint used. Some specific restrictions are also applied to avoid overuse of the send message function. 

Aircall implements specific hourly, daily and monthly limits that are different for each type of numbers and country. 

These limits are subject to change without prior notice to ensure proper usage.  

• US and CA numbers are given 1,000 hourly, 10,000 daily, and 20,000 monthly outbound segment SMS limits.
• French mobile lines are given 100 hourly, 1,000 daily, and 10,000 monthly limits to ensure conversational use cases.
• Other line limits are 500 hourly, 2,000 daily, 20,000 monthly outbound SMS segments.
