IP Office
Module Installation:
2.1 IP Address Notes
During installation the Unified Communications Module is assigned an IP address. The Unified Communications Module can
also use DHCP to obtain an address. It can also be given a DNS name.
The IP500 V2 system has two physical LAN interfaces: LAN1 and LAN2. The ports labeled LAN and WAN respectively. The
Unified Communications Module is physically connected to the LAN1 network of the system and needs to have an address
on that subnet.
These notes detail how the IP addresses are used.
·
User and Administration IP Addresses
User and administrator access to the Unified Communications Module and the applications hosted by the module
use the following addresses.
·
Unified Communications Module
A newly installed Unified Communications Module uses the IP Office system's LAN1 IP address for browser
access to the module's initial configuration menu. During that initial configuration, an IP address for future
access to the Unified Communications Module is set.
·
one-X Portal for IP Office
The one-X Portal for IP Office service running on the Unified Communications Module is accessed using the
module's IP address or DNS name suffixed with :8080 as the port number.
·
Voicemail Pro
The voicemail server service running on the Unified Communications Module is accessed by the Voicemail Pro
client using the module's IP address.
·
Internal Addresses
The following addresses are used only for internal connections between the IP Office system and the applications
running on its Unified Communications Module. These addresses are fixed and normally automatically set. However
you need to be aware of them as they appear in the IP Office system and one-X Portal for IP Office configuration
settings.
·
one-X Portal for IP Office Connection: 169.254.0.1
This address is used for the CSTA and DSML provider connections from the one-X Portal for IP Office
application to the IP Office. It is also used as the SNTP time source address for the Unified Communications
Module.
·
Voicemail Pro Connection: 169.254.0.2
This address is used for as the internal address for connections to the voicemail server. It is set as the IP
address of the voicemail server in the IP Office system's configuration. It is also used as the voicemail provider
address by the one-X Portal for IP Office application.
LAN2 and NAT Limitation
Traffic between the IP Office control unit and the Unified Communications Module is on LAN1 of the IP Office system.
Scenarios where users of the Unified Communications Module applications, especially one-X Portal for IP Office, are
accessing the IP Office and thus the Unified Communications Module via the IP Office system's LAN2 (WAN) port should be
avoided for more than 30 users.
They should also be avoided where NAT is being applied to traffic between LAN1 and LAN2. These restrictions should be
observed even when the IP Office system is in a Small Community Network where the H323 SCN trunks may be routed via
the other LAN.
