Our customer is one of the leaders in providing global corporate cloud based unified communication solutions for business. The company provides a cloud-based business phone system. It offers PBX features such as multiple extensions; call control; Outlook, Salesforce, Google Docs, DropBox and Box integration; SMS; video conferencing and web conferencing; fax; auto-receptionist; call logs; and rule-based call routing and answering. Customers do not require capital investment or maintenance contracts, which lowers customer costs and – as with most cloud-based technologies -- "potentially disrupts" traditional on-premises PBX providers.
