Rate Limits

Rate limits for the Voice API are set by account by your customer account manager. By default, rate limits are set to 3 CPS and 30 active sessions. If you think you may need additional voice capacity, please open a ticket with our Account Management team.

If a rate limit is hit when creating an outbound call the API will return a HTTP-429. If a rate limit is hit during a <Forward>, the error will be sent in to the disconnectUrl. If a rate limit is hit during a <Transfer>, the error will be sent to transferCompleteUrl. There are no notifications when inbound calls are rejected due to rate limits.
