4. Understand an End-User’s Perspective Customers fully understand the advantages of digital communications (cost reductions, better collaboration, mobility, etc.) Traditionally, telecom services are hosted. Customers have only terminals (phones), so the resistance is low to telecom SaaS. VoIP is not enough, the integration of all communication media is provided with Unified Communications. Business customers use free communication tools to increase their availability, sacrificing security, services, and reliability. Web/Email are dominant communication channels, phones must integrate with this Internet ecosystem. Legacy communication tools (e.g. faxes) are still used by business partners - they must be integrated in the new communication channels. VoipNow Platform Presentation 3
