Configure expansion modules

Last updated: 2026-07-15

Expansion modules (also called sidecars or key expansion modules) add extra BLF and speed-dial keys to the side of a desk phone. They plug into the phone's USB or dedicated expansion port and appear as extra function-key banks in Dromlik.

  1. 1

    Attach the module

    Power the phone off, plug in the module, and power the phone back on. The phone detects the module on boot.

  2. 2

    Assign keys in Dromlik

    In the phone's Function Keys tab, scroll down to the expansion module section. Assign each key the same way you assign phone keys.

  3. 3

    Reprovision

    Save and reprovision. The module reloads with the new labels.
