It is expected that your organization uses stateful firewall/NAT devices to protect its private networks. Unify Phone connections can traverse these devices using standard methods similar to Web Browser traffic. In particular, Unify Phone signalling, and media connections are always established in the outbound direction from the corporate network to the cloud. The firewall must allow connectivity as specified in the Unify Phone Administration, Administrator Documentation.

The intitial setup of a Unify Phone tenant is managed via an invite to a nominated administation user for the new Unify Phone tenant. This invite is managed and sent by Unify to authorised persons.

Unify Phone for OpenScape has inbuilt user management, users are created/added from the Unify Phone Tenant Adminstration web interface as part of the Unify Phone Cloud service.
