Aculab specializes in moving enterprise grade telephony applications to a cloud-based model. Rich telephony services have long been mission critical to enterprises across the globe. Initially, high-end applications (e.g. unified communications, speech recognition, text to speech, etc.) ran purely in an on-premise environment on dedicated hardware and software. With its cloud platform and the Aculab Cloud API, Aculab added flexibility and scalability to telephony services. Aculab users can custom tailor their telephony needs in Aculab's cloud, and pay for what they use. Recently, Aculab expanded its offering again by adding fax to their cloud portfolio.
