Microsoft Teams is the hub for teamwork in Microsoft 365 and the fastest growing business app in Microsoft’s history.  Teams allows free calls to other Teams users, and by adding an additional Microsoft Business Voice licence it enables the ability to call outside of Teams over the PSTN i.e. to any standard telephone number.

But the Business Voice phone system functionality is quite basic and is missing the functionality of a modern unified communications system; for small businesses that require a very limited telephone system and do not have existing telephone numbers to keep then it may meet requirements. In addition a Microsoft Calling Plan is required to provide a bundle of minutes, which can prove rather expensive.

An alternative is to connect MS Teams to CallSwitch2Teams, our feature-rich cloud-based Unified Communications phone system with free calls to landlines and mobiles, or to connect Teams via our Direct Routing and make calls via secure SIP trunk connectivity.

As well as improving on the features of Teams and providing free calls, take advantage of TSI friendly and personal support.  We have over 25 years of supporting business in the UK, from SME’s with a handul of users up to £1.05 bn turnover.  TSI can provide advice on best practices and guidance on how to configure your communications to work for your business.  Our support team are there to help at every step of the way – from managing the sometimes painful process of porting numbres through to training your staff and being there to troubleshoot any problems or answer any questions.
