We currently have an old phone system and we are looking to upgrade, we are still using PSTN externally so an upgrade is needed.
One of the options I have been looking at is to upgrade our 365 E3 licenses to E5 which comes with access to Microsoft's cloud phone system. I would then purchase calling plans and transfer our numbers across.
Just looking to see peoples feedback on using this system, how good its features were compared to other phone systems, if there was any vital missing and any sorts of hidden costs etc!
