Microsoft Teams Direct Calling


Microsoft Teams Direct Calling


Our Microsoft Teams Direct Routing solution, based on our SIPLink technology, enables you to easily make and receive external calls within your Teams environment.

Do you see Microsoft Teams as your Unified Communications solution, bringing together different departments to work productively and provide a consistent customer experience?

Perhaps you’d like to enable advanced calling features for your customer contact agents and record calls for external compliance? Or you’d like to allow calls with contacts who are using different collaboration solutions?

All of this is possible through our SIPLink platform. We can provide Direct Routing and add in advanced call features – as and when your business needs them.

Whether you’ve purchased Microsoft Teams from us or another provider, we can provide direct routing to you as a managed service. This offers a feature-rich and cost-effective alternative to the Microsoft Calling Plans.

Straightforward, reliable service

If you want complete confidence in delivery and guarantees that any issues can be resolved quickly, you need to work with a provider that has 100% control over their solutions.

At Node4 we have end-to-end control of our Microsoft Teams Direct Routing solution. Unlike providers offering SBCs only, our solution offers both elements – SBCs and SIPLink – for connecting you to the PSTN.

We’re not bolting together services and software with other providers – everything is hosted and managed by us. It’s our solution, in our buildings, on our cloud, delivered across our network.
