Buying and assigning the appropriate plans

The process is similar to buying and assigning any add-on to your Microsoft Teams subscription. You can find the phone system in the add-ons with Teams, and all you have to do is purchase and assign the licenses with your Office 365 account.

The best part is that you can easily assign licenses to a group or all your company members as per the requirements.

Getting the phone numbers

Before you start making the calls and managing things, it is imperative to assign phone numbers to your team members.

If you choose to go with Microsoft Teams as an office phone system then you can easily assign a new number for all the team members or even transfer the old ones from other phone service providers.

The three types of ways in which this can be accomplished are among – 

  • Login to the Teams admin center and assign new numbers to the team-mates – To do so, simply click on voice>Phone numbers and then click on add.
  • You can also get other numbers which are not available in the Teams admin center – This is the case in some areas; if you fall in this category, simply fill a form and send the request to Microsoft. The Microsoft team will personally help you to set up new numbers in this particular case.
  • Transfer your old numbers from other service providers into the application – Go to the “New local number port order” wizard in Teams and simply follow the instructions to add the numbers. If the list of your numbers is more than 999, you have to submit a manual request, and the team will set up the process for you.

You will be getting a list of all the available numbers as per your area. You can check the list and reserve the numbers as per your wish.

Getting service phone numbers for your company

You can also select and assign service phone numbers in your company for all the high concurrent calling services and features.

Toll Free numbers are part of every company, and these are beneficial for many reasons. Integrating these numbers is straightforward and similar to other standard numbers.

You can use these numbers for – 

  • Audio conferences
  • Auto attendants
  • Call queues

The biggest reason for using service numbers is that it can manage many calls at the same time. In this office phone system, you can easily add and manage hundreds of calls on service numbers simultaneously, whereas regular phones can only add a few calls at a time.

The steps involved in getting service numbers linked to Microsoft Teams are – 

1. Getting the new numbers

The process for getting new numbers is – 

  • Sign in to your account and go to the Teams admin center
  • Go to voice>phone numbers>Add new number and then click on new service numbers
  • Follow the instructions on the screen to book and integrate the numbers in a few seconds

2. Getting toll free numbers which are not available in the database

You might not find the numbers in your region, which is the case with many regions if you are facing that problem. Simply submit a form available on Microsoft’s website and their team will personally contact you and help in the setup.

3. Transferring your existing numbers to Teams

The process of transferring your service numbers is precisely the same as for transferring the standard numbers.

When you submit your request to port other services’ phone numbers to Microsoft, you are supposed to submit an LOA, the letter of authorization. This letter must specify all the details, including the type of number.

You have to make sure to fill in these details correctly even while talking to Microsoft’s team on call as the capacity of the phone number to host calls at the same time varies a lot. Giving the wrong specification to Microsoft can result in having a service number with limited calls support, which will defy its purpose.

Taking care of the assigned calling plans

You get a chance to select the calling plans during the start of the process and transfer your old numbers.

You will be asked a lot of questions and make sure to answer and select the right options. Make sure to add emergency numbers and also assign the number to particular team members.

Moreover, You can even define the roles to users and limit access to certain parts of insights according to your needs. Customization is the strongest and the best part of Microsoft Teams.

Setting up communication credits within Teams

This is one of the most critical steps in your setup. The reason we are discussing this, in the end, is that it is supposed to be set up in the end. You need to understand the other parts of the phone system to understand this effectively.

Billing is one of the essential parts of your phone system. Like all other parts, Teams will help you manage and understand the analytics of billing to make sure you are optimizing it.

Additionally, every phone system comes with individual subscriptions. Some parts of the system like the tollfree number system, actually work on prior payment.

This setup will help you make sure that there is no interruption to your system, and your team is performing at its peak all the time. Let’s understand what communication credits are.

  • An important to note in this scenario is that if you directly assign the communications credit license to the users in your company without setting it up in teams, you are always at the risk of running out of minutes or abilities, which will directly stop the complete system

The things which need prior payment and specific permissions include but are not limited to – 

  • Calling out to different countries and adding the people to conference calls
  • Audio conferencing using the service phone numbers

You have to start by buying the license and allocating it to your team members. To further set up rules and allocate funds accordingly, go to Billing > Purchase services and click on add-ons.

In this section, you will find communication credits. Just follow the information and steps on the screen to set up the complete process.

You also get the option to set up an auto-recharge feature. Using this feature you will get triggers whenever the balance in the particular category falls beyond a certain point, and the recharge is done automatically.

You can set up the notifications accordingly. And also set different rules for different teams or numbers as per your organization’s needs.
