O2 Voice for Microsoft Teams

Flexible, collaborative working

Business calls can cost less

O2 Voice provides telephony (PSTN) access into Microsoft Teams, replacing the need for PBX or UCaaS platforms.

Your teams can make ordinary calls to and from fixed and mobile devices as usual. Your business can save money by using your existing Office 365 licenses to replace traditional PBX costs.

Why choose O2 Voice for Microsoft Teams?

Full cloud offering

Don’t worry about the costs that come with setting up a new system from scratch. Created in the cloud, there’s no integration with your existing PBX platform required, offering a single platform fully compatible with SIP Trunking.

Uncompromising quality

Set your expectations high as O2 Voice is built into our network to the exacting standards of enterprise customers. Get an optional Quality of Service SLA when combined with our O2 Gateway Ethernet connectivity service.

Mobile integration

Wrap up all your calls to and from Office 365 with your mobile data when you choose our Unified Communications data bolt on. It’s all included no matter how many calls you make.

Offering choice between editions

We can offer public and private editions. And we can also offer you three different deployment options: managed deployment, managed configuration or self setup.

A smarter price plan

Capacity-based pricing means you’ll only pay for the call minutes you need. Minutes can be shared across your organisation and you remove the overhead of administering additional per-user licensing.

Making life easier

There’s no need to add or remove user licenses for PSTN. Shared capacity can be easily flexed up and down. And internal number transfer is simpler and faster for existing O2 SIP Trunking customers.

Get more out of Microsoft Teams

O2 Voice for Microsoft Teams is designed to help you if you’ve moved to Teams but haven’t decided to fully integrate telephony or you’re moving your telephony to Teams and want:

A fully managed, Direct Routing (PSTN) service – rather than taking on the hassle and expense of setting up and running additional equipment yourself
More flexible, cost-efficient calling plans – predict spend more accurately and lower call costs by sharing minutes between people. It’s smarter than paying by individual user each month.
The ability to have a guaranteed quality of service across offices.

Choose public or private editions

The service connects you over the public internet, which is especially useful for smaller remote offices or where you need rapid site setup.

O2 Voice for Microsoft Teams: Private Edition
