Section titled “How to Install a Polycom VVX Expansion Module (Sidecar)”

The Polycom VVX Expansion Module adds additional line appearances and speed dial keys to VVX series phones. It is commonly used by receptionists and administrative staff who manage a high volume of calls.

  • A compatible Polycom VVX series phone
  • A Polycom VVX Expansion Module
  • The interface cable (included with the module)

Remove the expansion module from its packaging and verify that the interface cable is included.

Power off the Polycom VVX phone before connecting the expansion module to avoid electrical issues during installation.

  1. Locate the Aux port on the side of the Polycom VVX phone.
  2. Connect one end of the interface cable to the Aux port on the phone.
  3. Connect the other end to the expansion module.

If your phone and module include mounting hardware, use it to attach the module to the side of the phone. This stabilizes the combined unit on your desk.

Power on the phone. It will detect the expansion module and begin the initialization process automatically.

After the phone boots, check the expansion module’s lights and display. You may see indicator lights flash briefly as the module is recognized.

Depending on your needs, configure the keys on the expansion module through:

  • The phone’s on-screen interface, or
  • The phone’s web configuration utility (accessed by entering the phone’s IP address in a browser)

Line keys can be assigned as BLF monitors, speed dials, or additional line appearances.

Press a key on the expansion module to verify it works as expected. Make a test call if applicable.
