Your business calls. Right inside Teams.
Make and receive external calls from the workspace your people already use. Infinitel supplies and manages the voice connection and SIP trunks together, with business numbers, calling capacity and specialist support around your Teams Phone service.
“Infinitel has implemented Direct Routing for Cloudbox, allowing our users to make and receive external voice calls using Microsoft Teams.”
Nick GoodenoughDirector, Cloudbox
Capacity around actual calling
Choose channels for the external calls in progress at the same time. You can support a larger team with fewer channels than people when they are not all calling at once.
Practical help with the move
We coordinate eligible ports, configure and test the supplied connection, and help your team use it. Your Microsoft administrator works with us on tenant access and Teams voice settings.
Your Teams workspace.
Our voice network.
Infinitel connects its SIP trunks to Microsoft Teams Phone through Microsoft-certified AudioCodes Session Border Controllers. Teams Phone supplies the phone-system features; our managed connection carries your incoming and outgoing external calls as an alternative to Microsoft Calling Plans.

What makes up your quote
See the ongoing voice cost, the calls you make and the work involved in moving. Microsoft licences remain a separate cost; your existing agreement may already include some of them.
| Cost component | What you are buying |
|---|---|
| Microsoft licences | Microsoft Teams and Teams Phone licences for the relevant users. Existing licences may already provide some of these licences; Microsoft Calling Plans are not required for Direct Routing. |
| Monthly voice service | Infinitel’s managed AudioCodes SBC connection and SIP capacity, sized for simultaneous external calls. The quotation identifies the channel quantity, recurring charge, service term and included support. |
| Numbers and call usage | The business numbers you order, any included call allowance and the rates for destinations outside it. International, premium and other non-standard calls need their applicable rates. |
| Setup and moving numbers | Voice configuration, call-flow setup, eligible number transfers and testing. Your quotation identifies the implementation work included and any one-off or third-party charges. |
| Optional additions | Contact centre, dedicated recording and additional analytics have separate licence and service costs. Devices, connectivity and specialist integrations are included only where specified. |

How does Direct Routing work with our Microsoft licences?
Teams and Teams Phone licences enable users to make business calls in Teams. Infinitel supplies the external voice connection through Direct Routing as an alternative to Microsoft Calling Plans. Microsoft licences and Infinitel’s voice charges remain separate.
Can we keep our numbers when we move to Teams?
Yes. Bring eligible UK and international numbers to Teams with a £0 Infinitel porting fee. Our voice team coordinates the transfer and your new call routes. Keep your existing service active until the transfer is confirmed; portability, timing and any existing-provider charges vary by number and provider.
Which approach suits a business keeping 3CX?
The native 3CX–Teams integration connects selected Teams users while retaining 3CX as the phone system. Infinitel’s standalone Direct Routing service connects Teams Phone directly to its voice service. We help you choose around the platform you want to keep.
What options help keep priority calls reachable?
Alternative routing and backup connectivity can give important calls another route. We consider these alongside emergency-location information, including remote users. Calling still depends on power, connectivity and Microsoft service availability; the service design determines which alternatives can help.
What do we check for calling in each country?
We establish the number type, local documentation, caller ID, outbound destinations and emergency-service arrangements. Number availability and full local PSTN replacement have different scopes, so each country’s requirements are confirmed for the service you order.
Put Infinitel voice behind your Teams calls.
Tell us your user count, current phone provider, business numbers, countries and renewal date. We will recommend the voice capacity and setup, check the Microsoft licences you need and return a quotation separating recurring, usage and one-off costs. Ask to see the everyday calling experience before deciding.
