UC Module

During installation, you assign an IP address to the Unified Communications Module. The IP Office system has two physical LAN interfaces: LAN1 and LAN2.

The Unified Communications Module connects internally to the IP Office LAN1 network and must have an IP address the same subnet as that interface.

Internal IP Addresses

The IP Office applications use the following fixed addresses for internal connections. You need to be aware of them as they appear in the IP Office system and one-X Portal for IP Office configuration settings.

169.254.0.1
The one-X Portal for IP Office application uses this address for its connections to the IP Office. The Unified Communications Module uses it as its SNTP time source address.

169.254.0.2
The IP Office and the one-X Portal for IP Office application use this address for their connections to the voicemail service.

User and Administration IP Addresses

User and administrator access to the Unified Communications Module and the applications it hosts use the following addresses.

Unified Communications Module
During installation, web browser access to the module's ignition menu uses the IP Office system's LAN1 IP address. The ignition process then configures a separate IP address to use for all future access to the module and its applications.

one-X Portal for IP Office
Web browser access to the one-X Portal for IP Office service running on the module uses the module's IP address or DNS name suffixed with port :8080.

Voicemail Pro
The Voicemail Pro client accesses the voicemail server service running on the module using the module's IP address or DNS name.

LAN2 and NAT Limitation

Traffic between the IP Office control unit and the module uses LAN1 of the IP Office system. For systems with more than 30 users, avoid scenarios where users of the module applications, especially one-X Portal for IP Office, access the module applications via the IP Office system's LAN2 (WAN) port. This also applies when using NAT on traffic between LAN1 and LAN2.
