3CX vs Bandwidth: Which is best for you?

We have 2 locations across USA and Mexico and we were able to connect both sites into one system.

The admin permissions options aren't amazing, and isn't convenient to assign access to other ICT staff. Since we have multiple sites and don't want to appear in each team, I need to use my supervisors account which has owner level access.

We were able to work with them and provide them with call examples over the course of days until everything was back under control and calls returned to optimal quality / performance levels.

Account reps are useless and elusive, some departments you simply can't work with directly or call, support is strictly by premade ticket with tons of required drop down options that often can't be crafted to have any relevance to your inquiry, and slow response on any inquiry.
