Add Geo-Redundancy Option
This guide explains the steps required to configure the Microsoft Teams Phone System with the Geo-Redundancy option. The initial installation must be completed beforehand.
1. Order the Microsoft Teams Geo-Redundancy Option
Before starting with this installation guide, the Geo-Redundancy option must first be ordered in the sipcall customer or partner portal under the menu item
Options → Microsoft Teams, and the domain must be verified according to the ordering process.
2. Create Domain Activation User
2.1 Create User
Log in to the Microsoft 365 Admin Center and create a new user under "Users" -> "Active users" using the previously created sipcall domain. This user is used to activate the domain.
The user domainactivation@cu<yourCustomerNumber>.msteams2.sipcall.ch is required temporarily and can be deleted after the configuration.

2.2 Add Microsoft Licenses
Assign an Enterprise or Business license to the user
(Microsoft 365 E1 / E3 / E5 / Business Basic / Business Standard / Business Premium) as well as a Phone System license
(Microsoft 365 Phone Standard), and complete the setup by clicking "Finish".
Alternatively, you can temporarily remove the license and add-on from another user and assign them to the domain activation user.

Wait at least 1 hour before proceeding to the next step.
Depending on Microsoft’s load, this may take longer. If it takes more than an hour, you will see a yellow highlighted message above the location.
3. Configure Teams Phone System using PowerShell

Create the online route:
New-CsOnlineVoiceRoute -Identity “sipcall_redundancy” -NumberPattern “.*” -OnlinePstnGatewayList “cu_____.msteams2.sipcall.ch” -Priority 2 -OnlinePstnUsages “sipcall”
