Call2Teams - Customer
Presence is a toggle enabled feature within the Teams Service page on the Call2Teams portal. It provides the ability for the PBX to mirror the presence of the Teams user.
To utilise this feature your PBX must support SIP Presence updated in the form of NOTIFY or PUBLISH messages.
All PBX's can support the custom call response codes based off the Teams Presence as this is handled by Call2Teams.
To enable presence you need to toggle this feature on via the Services - Teams Tab.
Currently there is a limitation within the Microsoft API on how many users you can subscribe to for presence. This limit is 250 users per Enterprise application. Based on the amount of licenses in the Call2Teams portal the Authorise button will determine how many Applications are required to cover all users for the service. You may experience multiple App consent boxes pop up which will All need to be accepted.
Once you press Save you will be presented with a Microsoft O-Auth Window which the Global 365 Admin must authenticate.
