Is it supposed to be that calls in SuiteCRM don’t sync to GoogleCalendar, but that meetings do sync (and sync both ways).
No evidence of that found yet, that other than meetings , any other module synced.
May be you can try this extension for 3 days. it eventually supports Meetings, calls and tasks.
it just adds another layer of security and support for a very high cost (if I had a company with many employees, including security, I, might think about it… the pricing model of a lot of these CRM is looney tooney for the little guy)
