As your organisation grow you may need to add more handsets but you could “Add Handset (limit reached)”… below is what to do.

Seeing the limit reached message means that your defined handsets has reached the level of your current subscription. To enable you to add more handsets you will need to click the “Upgrade Subscription” button (right of same screen) and update the “Quantity requested” field to be the total number of handsets you require. Once the subscription is updated you will be able to add your extra handsets.
