Microsoft Teams & Direct Routing
Turn Microsoft Teams into your business phone system — easy and hassle-free.
If your team’s already using Microsoft Teams, why stop there? With Direct Routing and Microsoft Teams SIP Trunking, we can transform it into a complete business phone system. SIP trunking securely connects Microsoft Teams to the public telephone network, so you can make and receive calls on your usual business numbers – right inside Teams, no matter where you are or what device you’re using.
The best part? You’re using tools you already know, while also saving money with our competitive Teams calling plans and flexible SIP trunking solutions.
So, what exactly is Microsoft Teams Direct Routing?
It’s the smart way to connect Microsoft Teams to the outside world – the public phone network (PSTN). This means you can call mobiles, landlines, and international numbers right from within Teams, using your existing business numbers and our flexible Microsoft Teams calling plans. No switching apps. No extra hardware (unless you want it). Just clean, simple Microsoft Teams telephony that works.

I recently had a new VC installed from the team at Prosum. David Colletta and his team were not only professional with the installation, but at all times, the communication was second to none from them to see at each step where we were at. The installers were brilliant, and to top it off, they cleaned after the installation leaving us nothing to do. How refreshing this was. Again, I cannot speak highly enough of the team at Prosum; their professionalism was second to none, and their on-time approach was exactly that on time! Please do yourself a favour and get the team out there to look at what your needs are for the business, big or small. They have it all! Well done and thank you.

We needed an experienced ICT VoIP provider that could implement a new telephony solution without affecting existing telephony services and business operations. After reviewing other providers, we selected PROSUM who was able to successfully migrate all our users onto the new NEC platform and complete the project in a timely manner. PROSUM continue to provide support for our NEC Telephony and Contact Centre environment and I would recommend their services to other organisations and enterprises.

Aitken Real Estate had to move office and sought David Colletta of Prosum advice about switching our telephony to the cloud. Extremely helpful, no-nonsense information and can get the job done. Their tech Antoine was sensational. No delays, no problems. Highly recommend!

Thanks to the PROSUM team for the successful migration of the Brisbane phone system. A great deal of planning and hard work in the preparation resulted in a smooth migration with zero downtime to the business – a reflection on the dedication and preparedness to the project. Thank you.
