The Free Edition is more for testing compatibility and basic functionality. It’s also (surprisingly) popular with small office / home office installations. It’s not meant to be a platform for capacity testing / full load testing.
We do offer a full-featured trial (Commercial Unlimited edition) for larger installations, see our FAQ at https://telium.io/faq1001 for more details.
UPDATE: As of August 2020 we now off subscriptions (monthly or annual) which might need your needs. It can be cheaper if you just want a quick trial but don’t plan to buy. (If you plan to buy then the trial edition may be cheaper)
If you want to contact sales@telium.io they can help you get started with a full-featured trial.
