Not directly a software development team but also consulting grouped by location and/or project.
We have a permant meeting open the whole day where everybody is free to join. Normally, it is started in the morning and a few people will join. After initial chit-chat everbody is doing their work either with the microphone off or on. When there are short topics to be discussed or questions arise it is directly done in the meeting and for bigger topics a new meeting/call is setup with the people involved. So most of the time it is quiet but you only hear the typing of your colleagues.
It basically mimics an open space office and direct human interaction where you can ask questions and overhear interesting topics with the advantage of being able to simply leave (or lower the volume) when you have a meeting or need absolute silence.
Additionally, we have a coffee break meeting in the afternoon for half an hour, that is also not obligatory, in which you can small-talk with your colleagues.
So, in total we have lots of opportunities to interact with colleagues but nothing is mandatory.
You said you weren't a software development team. What kind of functions do you have?
For me, and most people I've worked with, having an all-day meeting specifically to mimic the open office is not something we'd ever propose ourselves. Was it a bottom-up or a top-down decision? Is everyone happy with it?
Would rephrase it to not only SW team but also consulting.
The meeting grew organically: When I started in Corona times I had a few meetings a day with my mentor to talk about open points and questions. From there it evolved to a permanent meeting, also with others joining.
Attending the meeting is not mandatory; everybody is free to join and leave whenever they want. Some use it more regularly, some don't. I haven't heard of anybody not being happy with it.
