Why are businesses moving from PBX to Microsoft Teams?

A PBX is a company’s phone system and it’s mostly implemented out of hardware on-premises.  

Cloud PBX (when combined with PSTN Calling) is your phone system in the cloud, modern and tightly integrated with Microsoft Teams.  This means users get the voice capabilities they need—make, receive & manage calls; at work, at home, on the road; using phones, PCs and mobile, without the significant hardware investments attached to a traditional PBX system.

Should I switch from VoIP to Microsoft Teams?

Both VoIP and Voice Calling in Microsoft Teams offer flexibility and eliminate the need for storage space and unnecessary equipment costs.  Integrating Voice Calling in Microsoft Teams, however, can give you the extra bonus of unified colloboration and one learning curve for your team.

Take the example of a threaded chat experience in Teams.  You can group conversations by subject, saving time searching and piecing together communication across different channels, because integrating Voice Calling with Microsoft Teams means you'll use a single app for all your communication tools (Outlook calendar, meetings, chats, calls).  

New additions to your team will be able to catch up quickly, ensuring they can start adding value to discussions.

You'll get the same features you expect from any other professional calling solution, such as call queues and auto-attendant.  You'll also be able to view your call history, listen to voicemails and search for contacts, directly from the Teams app.  

And if you're in a meeting, you can have your voicemail messages transcribed.

Should I choose a third party calling plan?

Yes, if...

  • You want more flexibility than Microsoft's pre-set calling plans can offer 
    Microsoft's pre-set calling plans allow you to make and receive calls in Teams, but there isn't room for negotiation when it comes to flexibility. If you make a reasonable amount of outbound calls and you'd like to take advantage of unlimited UK calls, Direct Routing is the ideal alternative. 

    What is direct routing?
    Direct routing allows you to connect your telecom voice trunks directly to Microsoft 365 and Teams, so that your people can make and receive calls.   This means you won't have to commit to a Microsoft pre-set calling plan, allowing you to take advantage of cheaper call rates and more flexibility.


    How does direct routing work?
    Direct Routing integrates your Teams system to the PSTN using a Session Border Controller (SBC) and SIP Trunks. A SBC acts as a border between different networks to ensure your data is transferred correctly, and safely, between them. SIP Trunks, on the other hand, act as the essential connection between your business phone system, the internet and the traditional PSTN phone network. 

  • You have limited in-house support, experience or time
    Your business may have limited IT staff or resources, or staff who have little experience using Teams as a PBX or of telecommunications in general.  As a third party provider, we can provide you with essential step by step account management, install Direct Routing and any other equipment you need, whether you want to fill in a knowledge gap, or simply save your own staff time.


  • You have international calling requirements
    Microsoft's pre-set calling plans are currently limited to the UK and Canada while the roll-out takes place, so if you have international calling requirements, Direct Routing will provide you with the availability you need. 
      

How much does integrating Voice Calling with Teams cost?

  • Third-party providers should operate by a tailored approach.  This means an exact price isn't possible, because your quote should be based on a comprehensive review of your current circumstances and requirements.  You can rest assured, however, that choosing Direct Routing over Microsoft's pre-set Calling Plans can lower your recurring price per user per month.  At CMM Telecoms, we will provide you with a free, no obligation quote based on your unique needs so you can see how cost-effective this solution is, before making any commitments.
