Clinic-Patient communication for doctors - any experiences?

Hi guys,

I’m looking for a solution to make a clinic-patient communication possible via NextCloud Talk. This would include adding many permanent users (500+) to NextCloud Talk.

Do you have any experience with this or could refer me to a similar project?

The idea is to reduce phone times and email communication. When a new patient comes to the clinic, we would like to give him the opportunity to communicate to us (the clinic) via NextCloud for sharing documents.

Thank you for you help!
