Direct Routing or Operator Connect?
Teams can be connected to the phone network (PSTN) in four ways, including Direct Routing and Operator Connect. We compare them on the facts, so that you can choose the one that suits you, or combine them.
In short
- Operator Connect: the operator manages the connection, and you do not need your own SBC (Session Border Controller).
- Direct Routing: Teams connects to any operator through your own certified SBC. This gives the most flexibility.
- Calling Plan: Microsoft is the operator. It is the simplest option but the least flexible.
- Teams Phone Mobile: your mobile number becomes your Teams number, but it cannot be used for queues or switchboard functions.
- The options can be combined. If you have a PBX, a contact centre or analogue devices, you usually need Direct Routing for that part.
Four ways to connect Teams
Teams Phone is Microsoft’s telephony in Microsoft 365. You choose the connection to the phone network separately, and with it who provides your numbers and calls:
| Area | Calling Plan | Operator Connect | Teams Phone Mobile | Direct Routing |
|---|---|---|---|---|
| Numbers and phone network | Microsoft is the operator | A certified operator | A mobile operator; the number is your mobile number | Any operator via your SBC |
| Own SBC | No | No | No | Yes, certified for Teams |
| Cost on top of Teams Phone | Calling Plan per user | The operator’s subscription | The mobile subscription | The operator’s trunk, SBC and operations |
| Flexibility | Lowest | Choice of certified operators | Tied to the mobile operator | Highest: your own routing, any operator, multiple countries |
| Connection to an existing PBX | Requires Direct Routing alongside | Requires Direct Routing alongside | No | Yes, one of the main reasons to choose it |
| Numbers for queues and switchboard functions | Yes | Yes | No | Yes |
| Emergency calling | Enabled automatically | Enabled automatically through the operator | Via the mobile network | You configure the route and policy for the emergency number |
Which option suits you?
- Calling Plan suits small organisations without a PBX, contact centre or analogue devices that want everything from Microsoft.
- Operator Connect suits organisations that want to use their own operator without running an SBC, and have no PBX that needs to stay.
- Teams Phone Mobile suits staff who mostly make calls from their mobiles. It does not replace numbers for queues and switchboard functions.
- Direct Routing suits you if you have a PBX that will stay for a while, a contact centre or analogue devices. It also suits you if you need your own routing or survivable mode in branch offices, or want to keep an operator that is not in Operator Connect.
We deliver Teams Phone with Direct Routing, but it is not always the right answer. If Operator Connect suits you better, we will tell you.
You can combine them
All the options can be used at the same time in the same Teams environment, for different users, offices and countries. Microsoft gives its own example: Operator Connect for office workers, Teams Phone Mobile for mobile staff, Direct Routing for contact centres, analogue devices and older PBXs, and Calling Plan for small offices.
How to combine the options when your organisation operates in several countries is described under Teams Phone in multiple countries.
The situation in Sweden
- Calling Plan is available in Sweden, with pay-as-you-go, minute bundles and a plan that includes international calls.
- Operator Connect: in October 2026, Microsoft’s operator directory listed 34 operators for Sweden, including Telia, Tele2, Telenor, GlobalConnect and Dstny. The directory does not show whether each operator offers Swedish numbers, so check that with the operator.
- Teams Phone Mobile is offered by Telia as an add-on to business mobile subscriptions.
- Before numbers are acquired or ported, Microsoft may require a check of your organisation, which usually takes up to three working days.
Emergency calling differs
With Calling Plan and Operator Connect, emergency calling is enabled automatically. With Direct Routing, the administrator must set up a route and a policy for the emergency number, and both must be tested.
In Sweden, the emergency call centre looks up the address in a national database based on the calling number. The address must therefore be correctly registered with the operator for every number.

Common questions
More questions
Does everyone need a Teams Phone licence?
Yes, every user with their own number in Teams needs Teams Phone, however Teams is connected to the phone network. A Calling Plan licence is only needed when Microsoft is the operator.
Which option is cheapest?
It depends on the number of users, how you make calls and what you already have. Direct Routing involves SBC and operating costs but lets you keep your existing operator contracts. Calling Plan and Operator Connect have no SBC costs but their own fees. You can book a consultation, and we will work out the figures for your case.
Can we change connection method later?
Yes. Numbers can be moved between connection methods, but number porting needs to be planned with the operator and takes time. Numbers set up in Teams for Direct Routing must be released there before they are moved.
Can the contact centre run in Teams?
Teams has its own queues and switchboard functions, and contact centre solutions can be connected to Teams. With Teams Phone Mobile, however, you cannot have numbers for queues or switchboard functions.
