Ensure continuity of customer service operations

SIP Voicemail is a secure, scalable, and flexible voice messaging application specifically designed for contact centers and customer service. It allows companies to retrieve and respond to customer voice messages left in group mailboxes during peak times and after hours. This optimizes customer service continuity, since companies will no longer miss customer inquiries, and customers will no longer have to make repeated inbound calls to engage with the company.

Improve the customer experience and increase business opportunities

SIP Voicemail provides a superb, reliable customer experience for many high-touch customer service operations in industries such as banking and finance, insurance, healthcare, and more. When key customer service representatives, service specialists, and account managers have SIP-based personal voice mailboxes, companies are able to provide differentiated and personalized services to their high-value customers.

Easy management via a user-friendly interface

SIP Voicemail services are accessible through the telephone user interface (TUI) from a desk phone or agent desktop application. Users can easily manage their personal options with the web-based management interface.

Enable a cost-effective, fully integrated IP/SIP customer service operation

SIP Voicemail integrates seamlessly with SIP Server and Genesys Administrator to provide scalable, reliable, and secure voicemail services without requiring specialized hardware. With single-server or multi-server deployment options, Genesys SIP Voicemail supports great flexibility, streamlined management, and cost-effective customer service operations.
