Endpoint Manager - Polycom - Valet Parking works with button type "automata"

Commercial Modules Endpoint Manager

One more side-note to this - go here to get it working with VVX phones:

Polycom - Valet Park Retrieval quit working with EPM Update - Commercial Modules / Endpoint Manager - FreePBX Community Forums

The firmware included in EPM doesn’t work as of now (2021-04-02) - That might change in the future.
