I am thinking of buying a Yeastar S20 in the near future. With this I would like to use an audio door station (something like this: https://www.auerswald.de/en/products/accessories/audio-door-stations/tfs-universal-plus.html ). Is it possible to connect this analogue door station with the help of an S2 module to the S20? If yes: Will it work properly and stable?
With many thanks
