  • At GENBAND we’re all about continually pushing boundaries by introducing disruptive real-time communications solutions such as our Kandy platform. We are committed to improving the user experience by embedding real-time communications capabilities into as many of our everyday applications and endpoints as possible. – David Walsh, Chairman and CEO - GENBAND

  • The frothy talk of OTT startups and the breakneck pace of their global consumer adoption has certainly grabbed the attention of carriers. No one can afford to ignore a potential loss of $14B in the next year to current OTT players. The stats are staggering. – Patrick Joggerst, CMO


    Network transformation is part of the network modernization process by service providers working towards a migration away from legacy systems and archaic network infrastructure to a more efficient and highly consolidated network able to offer innovative services via Internet Protocol and cloud technologies. Not only do legacy systems require expensive upfront capital investments, they also incur ongoing operational costs and consume significant power and space. Network transformation helps minimizes these inefficiencies and the transformation paid for by operating-expense-based program options. Network transformation also ensures carrier-grade reliability and scalability, especially for regional or rural networks that demand infrastructure modernization.

    Unified communications (UC) solutions offer real-time communications in a bundle, providing streamlined and consolidated functions. With a unified communications solution, text, voice, video, and screen sharing collaboration can all be accessed from one integrated system. Not only can unified communications be applied to residential services, enterprises can merge their communications with their branch offices. Unified communications solutions also apply to contact centers and intelligent messaging, where greater demand of multi-function services is present. Going a step further, virtualization creates the opportunity for unified communications to be consumed or offered as a service from the cloud.

  • NFV

    Network functions virtualization (NFV) takes service providers towards more efficient, innovative and agile solutions for consumer and business communications service offerings by consolidating network capabilities into the cloud with virtualized functions. NFV allows carrier service providers to cut costs associated with monolithic and proprietary systems and approaches of today. With the migration to network functions virtualization (NFV) solutions, services become easier to configure and deliver, and new services become deployable in days, not years.

With the ability to embed on an array of systems, including mobile devices, business processes and workflows, real-time communication transforms the speed and quality of everyday communication as well as increase productivity and accessibility. Today’s consumers and businesses demand immediate communication at a growing rate, calling for high quality and personalized services.
