PLEASE don't kill me for this one!!

So I have been put in a situation where I need to Evaluate several hosted phone solutions for a large logistics company that has dozens of ACD groups and Attendants. There is skill based routing and queuing for most of these ACD groups. There is a hosted AI IVR with full voice in the mix here also.

The company wants to look at using Microsoft Teams Voice, or other hosted, for a corporate solution and achieve the enhanced functionality that most hosted solutions offer. ( easy to deploy in remote locations, no hardware, no manual updates, technology for product always being developed) (Trying to be a little vague due to company privacy)

My thing is does it suck?????????? OR is it the greatest thing to sliced bread?

I'm old school and want an on prem solution with desk phones for all 500 plus agents, but with this influence they want no hardware liability unless it is absolutely necessary.

Has ANYONE had or know someone with any experience with Microsoft Teams Voice?

Thank you in advance!

As the great Bob once said, "Its a SWITCH its either OFF or its ON!"
