Overview
Phone App is available as an add-on to existing PBX services.
If the option is not available in the portal then the service has not been provisioned to the account and needs to be enabled via the licensing provider.
Phone App is currently only available on the service for PBX users.
Follow these steps to purchase and setup the Phone App.
1. Purchase the Trial or Paid SKU
Phone App is an Add-On SKU which must be ordered for each customer account through support.
Note:
Phone App licenses must be purchased in addition to PBX user licenses.
PBX user licenses allow users to be connected to their PBX service.
Phone App licenses allow for routing calls via Microsoft using the Teams Phone App add-on application.
Once Trial or Paid SKU is assigned, support will be sending a global admin invitation to your requested email address where you can proceed to login into your iplogin4teams admin portal.
2. Enabling the Phone App Service
Each step in this section corresponds to a numbered section on the accompanying screenshot below.
- After purchase, the Phone App must be enabled on the customer's portal, under the Services tab. Click the toggle to the On position
- Click "Authorize Phone App for my organization"
- Click Sync Now
3. Adding users for Phone App
The sync will populate the service with users who have the Phone system license, as shown below.
Configure these with the PBX SIP Credentials.
Click Save.
Once Saved, run Sync.

Overview
Phone App is an add-on to the iplogin4teams PBX license that embeds a dialer in Teams for native calling.
The Phone App is automatically loaded into the users Teams environment as a part of the service.
There are some limitations to the user experience compared to the full Microsoft ‘Phone System’ calling experience.
Since the Phone App does not enable any of Microsoft Teams’ native phone system capabilities (e.g. auto attendant, call queues etc.), customers/users should rely on the PBX capabilities provided by their existing phone service to deliver the feature set that a business user would expect.
Phone App users can exist in the same customer organization as a Microsoft Phone System 'Standard User', so the customer can choose which capability to assign users as required.
Note: For a user to operate with the Phone App service they must be in Teams only mode. If they are in Skype for Business mode, the Skype 'S' symbol will appear by their name in Teams when being contacted from another organization. If this is showing then the user will not work with Phone App.
Refer to Microsoft documentation for moving users between Skype for Business and Teams modes here
Note: Microsoft are changing the name of the Phone System License to Teams Phone License. Please be aware that references to both may continue to co-exist for a time.

Configuring Microsoft 365 to work with Phone App
Phone App relies upon the service global network to place calls directly to Microsoft Teams users through a method referred to as ‘external access’.
External access is managed within the Teams admin center, and a function of this management is to enable calls from the domain used by the service for Phone App.
Microsoft tenants have this capability fully enabled by default but if external access has been restricted then this is managed in the Teams admin center:

Using the Microsoft Teams Admin Center
Go to https://admin.teams.microsoft.com/dashboard
In the left navigation, go to Users > External access.
Turn on the Users can communicate with other Skype for Business and Teams users setting to enable External Access.
.If all Teams external organizations are to communicate with the organization, skip the next step; the Microsoft tenant is ready for external access.
If a limit to the organizations that can communicate with users in the organization is needed, either allow all except some domains, or allow only specific domains.
- To limit communications to specific organizations, add those domains to the list with a status of Allowed. Once these are added any domain to the Allow list, communications with other organizations will be limited to only those organizations whose domains are in the Allow list.
- Be sure to add the Phone App domain (yourdomain.com ) to the Allow list.
- Click Save.
Phone App also relies on the Microsoft 365 Tenant or User to be in "Teams Only" mode. Depending upon organization requirements, it may be easier to move the entire Microsoft 365 tenant to Teams Only mode, or this can change can be made to an individual user.
To check this setting please follow the steps as shown in the screenshot below:
- Navigate to Teams upgrade settings
- Under Coexistence mode select Teams only
- Click Save
