#AUTOMATIC CODE SNIPPIT IN TEAMS CODE#
This second example is widely applicable to both blocking a large range of numbers such as a whole area code but also useful for blocking an entire country.īefore we get into this one, however, we just need to draw some attention to the implications of it. This, therefore, has the effect of matching all numbers between 400 and 499. You’ll see the similarity between this at the previous single number pattern but here we say instead that we want to look for any number between 0 and 9 and we do it twice. Maybe you know that a telemarketing company that is spamming you with calls owns a range of numbers that end between 400 and 499 and you want to block that range only. The first example is where you want to block incoming calls for a range of numbers.
Block incoming calls for rangesīeing able to block incoming calls for a single number above is easy but what about if you want to block a range of numbers or perhaps all numbers from a particular country? This is where it gets more difficult because although Regex is extremely powerful, a mistype of the pattern could lead to unintentional matches being applied as we’ll show below.
#AUTOMATIC CODE SNIPPIT IN TEAMS PLUS#
The backslash symbol before the plus character means to match the plus explicitly. In Regex, the ^ symbol means the start of the pattern string and the $ symbol means the end of the pattern.
To block a UK mobile phone number, for example, the pattern would look like “^\+447123456789$” substituting the digits shown for those of the number you want to block. The number needs to be defined in the E.164 telephone number format which means that it is prefaced with the plus symbol and the country code. We give the rule a name and can optionally as a description too which we would recommend making later review and troubleshooting easier.įor the pattern itself, we use a Regex pattern match enclosed in quotes. This is done using the PowerShell command New-CsInboundBlockedNumberPattern. To set-up a block we need to create a new number pattern.
If you are working with the feature to block number(s) then take care firstly to ensure that your Regex patterns are valid using an online tester and also test with Microsoft Teams itself to be sure the rule works as intended. In our testing of the feature, we found that sometimes new rules take effect within a matter of minutes whereas sometimes they can take several hours. In the UK, we found, for example, that making a call from a Three mobile phone resulted in the call being dropped with no warning whereas an O2 mobile phone gave the caller the voice prompt. Depending on the carrier or network used by the person making the incoming call they will either be simply disconnected or they will get a message stating that their call cannot be completed.
Once active, rules simply cut the calls off at the other parties end immediately. Rules are created using number patterns and are declared as Regular Expressions (Regex). The feature is enabled at the tenant-level by default but there aren’t any rules applied by default so simply creating some rules automatically starts working. The documentation for doing this is neatly tucked away at. This isn’t something that’s visible or available in the Microsoft Teams Admin Center and requires the use of PowerShell. One of the more hidden features in Microsoft Teams is the ability to block incoming calls from a number or a range of numbers at the organisation level. Block incoming calls features in Microsoft Teams The customer needed a way to block incoming calls from that number and we figured that this was one worth sharing for all to see. Last week, a customer contacted us about an issue they were receiving persistent, unsolicited calls in Microsoft Teams from a phone number.
