Thank you Andrew,

Do you also know if there is a possibility to try this feature with a softphone before buying an hardware phone?

Thanks

A number of phones can do this, and some even have add-on modules to
increase the number of buttons you have to play with. The ones that come to
mind are:

   - Snom 370 + Expansion
   - Cisco SPA508G + SPA500S Expansion Module

There are most likely others too, I'm sure other people on this list will
add other suggestions.

Obviously choose what best fits your budget and requirements.

You'll need to configure presence in FreeSWITCH inf your sofia profile,
then configure the keys as required and the extras in the dialplan for call
pickup. How to configure the phones varies.
