In their own words
BBOX Voice Messaging
BBOX Voice Messaging is a business-to-business service for sending automated voice calls from a web platform or API. Messages can use uploaded MP3 or WAV recordings, or text converted into synthetic speech. Text-to-speech settings include language, gender, and tone. Calls can reach mobile and landline numbers, with multiple languages and voice options. Campaigns target contacts or audience segments; users configure caller ID, schedule, voice, language, and timeout settings, then track delivery, answer rates, and campaign performance. Call and ring timeouts are configurable, with a minimum timeout of 10 seconds, and the service can capture the first keypad digit from 1 to 9. Integration options include REST API, SMPP, and the web platform. Voice campaigns can be managed with SMS, WhatsApp, Telegram, Viber, and Email. Pricing is on request, with charges based on successful call attempts unless the applicable price or coverage list says otherwise. Coverage and legal availability depend on destination rules and required permissions.
