The My-Cloudline UC application lets you login to the My-Cloudline telephone server with your My-Cloudline account.
You can tell the server to establish a SIP call between a chosen contact and a device like your office phone, mobile phone or another number.
Other features include managing favorites, listening to voicemails, creating conferences and setting your preferred device.
The app cannot be used without a My-Cloudline account, which can only be acquired over My-Cloudline directly.
