    Want to keep building your Microsoft estate?

    You’ve made that initial investment in Teams – why not get more from it by using it as your office phone system?

  • Mini_Question_1

    After an alternative to Microsoft Calling plans?

    If you’re looking for a more cost-effective, flexible option, then our Direct Routing solution provides exactly that.

A flexible and cost-effective alternative

Microsoft Teams Direct Routing, based on our SIPLink technologyenables you to easily make and receive external calls within your Teams environment

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. 

How does Microsoft Teams Direct Routing work?

Direct Routing links the PSTN to Teams through two key elements: Session Border Controllers (SBCs) and SIPLink, our SIP Trunk service: 

Our Microsoft-accredited SBCs provide the interface between your  Teams tenant on Microsoft’s cloud service and N4Engage’s network. They provide security and interoperability between the two networks and allow calling functionality.

Our SIPLink service is the essential component for connecting you to the PSTN. It is fully hosted and managed by N4Engage and provides the interface between the Microsoft Teams SBCs and external telephony users. We can provide the full range of SIPLink features to Microsoft Teams users, including national and international inbound numbering, advanced call routing and bespoke integration to other telephony systems connected to SIPLink.

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.

Here at N4Engage, 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.

Tailored calling solution for your business

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.

Our Packages

To utilise our Direct Routing solution, a Microsoft Teams Phone System licence is required. This is included in some Microsoft bundles, or can be added to others at additional cost.

Once the Phone System licence has been activated, you can deploy our Direct Routing solution for the calling service. This turns Teams into a fully-fledged PBX, providing you with phone numbers and the method to make and receive calls.

We’ll make it a seamless transition, whether you’re migrating from an onsite PBX, Skype for Business or simply want a fully functional Microsoft Teams to sit alongside your business phone system.
