When making the jump to adding voice calling to your Microsoft Teams you are faced with two options.
1 – Add Calling Plans on a per user basis from Microsoft.
2 – Add Direct Routing with a Specialist VoIP Provider/Integrator.
If you have sub 5 or even 3 users, then it may make sense to opt for the Calling Plan bolton on from Microsoft at £4.50 per user. However anything over 5 users it would make more sense to work with a VoIP provider who can provide Direct Routing SIP Trunks to your Office 365 tenant.
Direct Routing is typically charged on a per channel/SIP Trunk requirement, thus negating the requirement to add it to every user.
I would expect most companies have a 3 to 1 ratio on channel requirements or even less. So a 50 user company could in theory only require 16 channels of direct routing.
The other issue is dealing with Microsoft to assist in number allocations / number porting? You only have to google reviews on peoples experiences to read some real horror stories of companies with loss of service on numbers for days when porting.
Fuse 2 ensure number porting is smooth and guaranteed!
