Cloud Telephony for the Enterprise at ITEXPO is a topic of interest in improving business processes and revolutionizing voice development through cloud communications. The discussion around this is varied, with different approaches including applications behind the firewall, with a hosted partner or through elastic mechanisms such as Amazon's EC2. Twilio will be hosting an event, where Evan will discuss how cloud telephony can benefit businesses, and attendees can also learn from customer engagement experts to improve their own communication.
