IP Office
Restrictions
Only one Voicemail Pro server can be installed on a single Small Community Network (SCN).
Centralized Voicemail Pro is the only type of voicemail service that can run on a Small
Community Network (SCN.
The number of simultaneous voicemail users is restricted by the Voicemail Pro license on the
central system, up to the maximum number of data channels for voicemail supported by the
central system's control unit.
For extensions on the remote system, access is also restricted by the number of
available
VoIP and VCM channels on that system.
Voicemail Lite and Embedded Voicemail cannot be used with Centralized Voicemail Pro.
Supported Remote IP Office Voicemail Features:
Not all Voicemail Pro features are available on the remote IP Office systems, for example hunt
group queuing messages are not supported. Currently, the only features supported for remote
sites are:
Automated Attendant.
Voice Messaging (leaving and collecting messages).
Call Recording.
Dial by Name Directory.
Licensing
The most commonly seen problem in Centralized Voicemail Pro is misunderstanding the licensing
requirements.
The voicemail licenses are entered on the central IP Office and validated against its Feature Key.
The remote IP Office systems do not need any voicemail licenses.
By default each IP Office uses a broadcast address to locate a Feature Key Server PC and
validate its licenses.
Once a Feature Key Server has validated licenses with one IP Office it will not do validation for
another IP Office unless rebooted.
Given the above, we strongly recommend that in any multiple IP Office network, the License Server IP
Address (System form | System tab) on each IP Office is set to the specific address of its Feature Key
server or blank if using a serial port Feature Key. If a remote IP Office does not have a Feature Key
Server (because it is not using any licenses) enter 0.0.0.0.
It is important to note also that the Voicemail Pro server will operate for 2 hours without license
validation. This can cause Voicemail Pro and centralized Voicemail Pro to appear operational following
installation and to then stop.
