8x8's Polycom VVX Sidecar expansion modules come in a 28-key digital color model and a 40-key paper label model. Use of Polycom VVX Sidecars requires a subscription to 8x8 Power Keys service, as well as any of the Polycom VVX IP phone models below:

Up to 3 Polycom VVX Sidecars can be cascaded together to maximize the amount of line keys available. (Joined Sidecars must be the same model.)

To connect your Sidecar

Note: The following instructions are also available direct from Polycom.

  1. Connect the base stand to your Sidecar at the same angle as your phone’s stand. 
  2. Position the phone and Sidecar next to each other on a flat, level surface, as closely together as you can.
  3. Locate the holes for the thumb screws (between the top-most and middle stand slot).
  4. Hold the metal bracket so that the four tabs face away from you, and the arrow on the back of the bracket points up.
  5. Position the holes in the metal bracket over the thumb screw holes. The four tabs on the bracket fit in the top-most and middle stand slots.
  6. Insert the thumb screws in the holes, and tighten using your fingers. 
  7. Turn the phone and Sidecar upside down on the table.
  8. Insert the cable connector between the AUX port on the phone, and the AUX 1 port on the Sidecar, then thread the cable through the cable grooves on the Sidecar and phone. If the phone is connected to the network, the Sidecar will automatically power on and start up.
  9. To connect another Sidecar, attach another cable connector between the AUX 2 port on the first Sidecar and the AUX 1 port on the second Sidecar. (You can connect a maximum of three Sidecars to one phone.)

To configure your Sidecar for use

Depending on the Power Keys plan(s) you have purchased, your Sidecar(s) can be configured for a combination of BLF keys (which allow you to monitor extensions to see who is busy and who is available) and Speed Dials.

Power Keys must be set up in Account Manager by a system administrator. If you do not have access to Account Manager, please contact your phone system admin to configure Power Keys for your Sidecar(s).
