3CX vs Intermedia Unite: 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.

Through the use of mobile apps and video conferencing, our ability to broaden communications within the company, outside vendors and partners has simplified our unique hybrid office platform.

Can't figure out how to set a different and unique ring tone for my cell phone to let me know it's the "office line' ringing.
