Call for tenders

Openfield asked several cloud service providers to participate in a comparative study of their cloud telephony solutions. The main goal was to assess the Cloud phone systems, tailored especially for the SME’s communications needs. Four of the leading telecommunications operators responded positively. Three of them agreed their entire communication infrastructure to be tested and evaluated for this study. To analyze and rate vendors’ performance objectively they had to compete on equal terms. Therefore providers had to submit their Cloud telephony offerings for the same fictional  SME.

The profile of a SME matched several criteria:

• A small to medium company that occupies one building or office
• A single reception desk and two conference stations
• Fourteen softphones are installed on-premise
• The number of simultaneous communications – voice calls, video meetings, instant messaging service, file sharing – is fifteen
• The company consists of thirty employees
