3CX vs Dialpad: 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.

Dialpad has allowed or remote team to have some continuity with incoming calls & texts & made it easier to record the information covered in each communication.

The lack of accountability and responsiveness from Dialpad's customer support is the biggest downside. Despite numerous attempts to resolve a billing issue, they consistently fail to provide solutions, leaving us overcharged for services we don't use.
