If you have the knowledge to run the event with interpretation, then buy the license for a month - note the owner of both licenses MUST be the same ZOOM account!
If you have no experience running a meeting/webinar/event with interpretation, I strongly suggest that you get a managed service or a consultant to assist you the first time to ensure that your event runs smoothly.
Interpretation = live translation by people for people
We specialise in organising and running events with interpretation.
