Service providers that used to offer enterprises and SMBs basic communication services around voice and data are now facing an increasing demand for more advanced services. As the workplace embraces popular trends such as distributed enterprises, remote workers, a mobile workforce and a growing number of small businesses, new data-intensive service offerings have emerged to accommodate these trends. Unified Communications, SIP Trunking, mobile VoIP, recording, and managed and hosted contact centers are some of the important services.
