Avaya Cloud Office Phone Plugin for VMware app integration for RingCentral

In a typical VDI environment, Avaya Cloud Office Phone acts as any other application running in a virtual host environment. However, telephony media stream must make several extra network hops to reach the RingCentral data center. If the network infrastructure is inadequate or unstable users may experience degradation in audio quality due to these extra hops.

With the Avaya Cloud Office Phone Plug-In for VMware we work to establish a direct media channel from the local user machine where the VMware plugin is installed to the Avaya Cloud Office data center. This allows us to minimize the number of network hops and optimize the delivery of audio between callers.


  1. Make and receive VoIP calls over WiFi, even while traveling internationally, or over 3G/4G without using your carrier minutes.
  2. Send unlimited text messages to anyone in the US and Canada for free.
  3. Never drop another important call. Call handoffs allow you to switch from using a data network to a carrier network during a call.
  4. Visual Voicemail makes it easy to see who left you a message, forward messages, and tap to return calls based on your priorities.
  5. Bring your own device (BYOD) to work. Personal contacts are conveniently separated from your company directory.
  6. Single business identity - use your one business number for calling, texting, and faxing.
  7. Manage active calls efficiently with advanced call controls to transfer, record, flip, or park the call.
  8. Reply to calls with automated text-to-speech messages, or send callers to voicemail without interrupting the current call.
  9. Department text messaging sends one text to all department members. See the entire conversation thread on one screen.
  10. Host and attend online meetings from your Android, and easily collaborate with screen share, integrated chat, and file sharing from your desktop or cloud storage (Box and Dropbox).
  11. Hold unlimited conference calls. Start or join calls with one tap, and invite up to 1000 participants by email or text.
  12. Easily send a fax from your Android and attach a note, photos, or files from cloud storage (Box and Dropbox).
  13. Manage your phone system from the palm of your hands
  14. Update and manage your entire system of locations, departments, extensions, and direct numbers wherever you go.
  15. Enable BYOD for all employees, reducing TCO for devices while improving productivity.
