Ensure the message is heard
With traditional SMS, you can ensure the message is sent (by checking status reports) but you don’t know if it’s been read. With Voice SMS, the recipient can acknowledge that the message has been listened to, offering peace of mind and an audit trail.
Ideal for mission critical SMS
Our Voice SMS service has an intelligent retry strategy which means we’ll keep calling the destination number if its engaged or unavailable. This feature makes Voice SMS perfect for emergency SMS messaging.
Works for all user groups
Traditional SMS doesn’t work for some user groups – those who don’t have a cell phone, the elderly, the blind, partially sighted and people who are driving can’t read their text messages. In such instances, Voice SMS is often a better choice.
Available in multiple languages
Voice SMS is available in English (US, UK and Australian accents), French, Spanish and German. If you require a language which isn't currently supported, just get in touch with us.
Our Voice SMS service can be accessed from Echo, our Web SMS tool and the Esendex API. Each has a wealth of features. Here’s a brief outline of the Voice SMS features. For the complete list of features that can be accessed via Echo and the Esendex API, click on the following links:
