Skype for Business Server Multitenant Hosting Pack is a Microsoft® Unified Communications
(UC) hosting solution for telecommunications and hosting providers which enables hosting
partners to deploy a single instance of the server software to securely and economically host
multiple tenants with a rich, fully integrated UC solution. To connect the phone to a hosted Lync
environment (LHP), you need to configure the hosted service provider's domain name (FQDN).
Note: In hosted environments, it's common practice that this hosted domain name is different
to the enterprise's domain name. Refer also to 400HD Series IP Phones for Skype for
Business Hosting Partner (LHPv2) Environment Configuration Note.
To configure a phone for an LHP environment, configure the address of the Outbound Proxy as
the hosted service provider's domain name (FQDN).
To configure the address of the Outbound Proxy:
1. Open the Outbound Proxy screen (MENU hard key > Settings > Outbound Proxy).
2. Press the right rim of the navigation control to set the 'Use Hosted Proxy' field to Enabled.
3. In the 'Address' field enter the hosted service provider's domain name (FQDN), configure the
'Port' field (default = 0), and then touch the Save softkey.
