    with end-client Royal Caribbean to implement a Unified Communications solution onboard Royal Caribbean’s fleet of cruise ships. The teams worked together to successfully implement a Cisco Call Manager solution that integrates CTModule’s software onboard. Past and current successful projects include Royal Caribbean’s new-build ship implementations as well as older ships that require refurbishment and custom legacy integrations utilizing CTModule’s software. The solution scales from projects that have included 150 endpoint installations to larger ships with over 5,000 endpoints integrated.
