On many occasions in my day-to-day role, I am asked how to do specific things within Microsoft 365. And like call outs over social or threads raised up on the Microsoft Tech Community, I always look at these as great opportunities and a rich source of inspiration for the blog. So, this week a good colleague of mine who works at a Microsoft Partner got in touch - and they had a customer who asked them how they could block a specific number which was making nuisance calls to a few of their team. Now, as opposed to implementing user level blocks by the impacted individuals, they wanted to block this number for all users. This meant they wanted to block the number tenant wide. Yet they couldn't see anything in the Teams Admin Centre how to do it. Solution? Tenant blocking of PSTN numbers can only be done via PowerShell. But thinking on this further, this could really benefit from being an internally managed service in the same way as applying for a blocked app. So, let's have a looking at blocking which is not just utilized for nuisance calls, but also robocalls, competitor calls and a number of other org specific reasons. It's good to come around again to a bit of Teams Calling. I always like to keep my hand in.
