IMS Installation Alternatives
The IMS Server actually consists of two components:
IMS Gateway Service.
IMS Voice Service.
These components can be installed separately if required. However the following rules must be followed:
The IMS Voice Service must be installed on the Voicemail Pro server PC.
The IMS Gateway Service can be installed on either the Voicemail Pro server PC or the
Exchange Server PC. Installation of the IMS Gateway Service onto the Exchange Server PC
requires more installation steps but may improve performance in some systems.
Before Installing IMS
Before you start to install IMS you must check that:
Microsoft IIS Web Server is installed.
In the IP Office Manager the IMS license has the status of Valid and Unlimited. This is because
IMS operation requires a license in IP Office in addition to the Voicemail Pro licenses. The
required licenses are:
Voicemail Pro (4 ports) plus Additional Voicemail Pro (X ports) licenses up to the total
number of port required or supported by the IP Office control unit.
Integrated Messaging - Enables operation of IMS with Voicemail Pro.
For more information, see the IP Office Manager help.
In the IP Office Manager the Voicemail Email settings are switched off. This is because the IP
Office configuration settings for each user do not apply to IMS. They are usually switched off by
default but it is advisable to check before you start the installation. For more information, see the
IP Office Manager help.
A domain user and mailbox account exists called IMS. For information about creating this
account, see Creating and Configuring the IMS Account.
The Outlook or Exchange client on the server PC is configured to use the same account. For
information about creating this account, see Creating and Configuring the IMS Account.
Important
Only when these checks have been completed, are you ready to start installing the IMS and
Voicemail Pro software. For more information, see Installing the IMS and Voicemail Pro Software.
