The Polycom VVX EM Expansion Module is an easy plug-and-play device that requires no setup!
This new updated Polycom sidecar is built to plug into the side USB port on the Polycom VVX 450 and grab configuration and power directly from the host VVX 450. This expansion module adds an additional 90 presence keys. This allows for 50 BLFs (including the 11 BLFs on the VVX 450’s display) plus an additional 51 favorites, or speed dials. This solution is ideal for a user that regularly transfers calls to off-net numbers.
