Microsoft Teams Direct Routing Partners UK Recommendations
Also looking for a partner for DRaaS. It's tricky. Resellers are banging on the windows offering it, although all they are is middle-men to the carriers. They have offered a "carrier agnostic" model where the calls will be routed via the best offering at the time. You could go with one "good" carrier (e.g Ring Central) but can be more costly.
Has anyone used Sippio? This looks like the sweet spot....
You're correct that a lot are middle-men and in all honesty that's what most DRaaS providers are. They carry voice traffic from the SIP Trunk carriers through resilient Azure based SBC's and into the Teams "cloud". That's one of the issues as there's a lot of companies that have set themselves up without knowing a thing about Telecoms and then leave it up to the end customer to setup their Teams environment. There's no qualification\accreditation to set yourself up as a DRaaS provider so you do have to be sure who you are working with and they are competent. I think where my company differs is that we work with the customer to get their tenants setup correctly even offering a free Proof of Concept trial so they can test voice quality, setup some Call Queues etc so they can get a feel of the product.
I think the SIPPIO model is good for a small number of users but from a price point of view can stack up if you're talking about £9 per user per month. You've also got your Office 365 licenses on top of that (Phone System etc).
Let me know if I can help. Details should be in my profile.
