Voicemail Pro installation - IP Office Info

7.1 Centralized Voicemail
Centralized Voicemail Pro:
Within a Small Community Network, a single Voicemail Pro server can be used to provide voicemail features for all the IP
Offices in the SCN.
One IP Office is configured for operation with the Voicemail Pro server as normal, including the license for voicemail
operation and the features required. This IP Office is then regarded as the central IP Office for voicemail.
Within the other IP Office systems, the voicemail settings are configured to indicate that they get their voicemail services
from the central IP Office. These IP Offices do not need licenses for voicemail (except for ContactStore and or UMS if
required).
With the International Time Zone functionality available on the central Voicemail Pro server, the users of the IP offices
located in different time zones across the globe receive messages in their voicemail system with their respective time
stamp. In the sample scenario, the three IP Offices located in different time zones connect to each other. Two of the IP
Offices are located in different geographical locations and are connected to the central IP Office. The Voicemail Pro server
connects to the central IP Office. In this setup, the system stores the voicemail messages on the centralized Voicemail
Pro. Each IP Office is set up to use Simple Network Time Protocol (SNTP) .
In the centralized Voicemail Pro setup, the time source of the IP Office network must be SNTP (Simple Network Time
Protocol).
Simple Network Time Protocol (SNTP) is an Internet standard protocol (built on top of TCP/IP) that provides accurate
synchronization to the millisecond of computer clock times in a network of computers. It synchronizes all the IP Offices in
an SCN configuration.
