Tooling issue is one thing. Choice of VoIP is MS Teams since it comes free with the IT package and Teams is complete shit to use.
Second it the actual logistics. It was always pain to accommedate the one or two remotees by having some kind of conference phone-thing. Over all it is just way more convenient and nicer to talk face to face. In my opinion even all online meeting is better than hybrid one.
Instead you should be an advocate for mixed teams. Why can't your remote coworker just zoom into the meeting with you onsite?
We can all be accommodating to each other.
