Keep your Business
Running with
Polycom and Ribbon

Communication is key to any good business.
Any disruption to that capability is adisruption to your organization’s revenue.
Polycom® VVX® Business Media Phones, Skype for Business Edition
are certified with Skype for Business in Office 365, providing seamlesscalendaring with Microsoft. Simply connecting your VVX phone to Skypefor Business provides convenience when joining a conference callwithout sacrificing Polycom-quality audio.
VVX phones use the Microsoft Phone System to route calls when connected.
The ability to route calls can be lost when the connection is disrupted by aWAN failure. This immediately affects your organization’s ability to create
revenue. It’s important to have a backup plan should this occur.
