9.1 Installing IMS

Integrated Messaging Service (IMS) is an addition component to Voicemail Pro. It allows users to deal with voicemail
messages through their normal email interface (Microsoft Outlook or Exchange). Voicemail messages can still be handled
conventionally using just the telephone.
With IMS, voicemail messages are presented with a special icon in the user's email inbox. When a voicemail is opened, a
special form appears which enables the user to play back the message on their telephone. The voicemail message itself
remains on the voicemail server.
When a voicemail is read, forwarded or deleted, either from the email or by using the phone, its status is reflected in
both the mailbox and the email inbox.
·Playing Messages Through the PC
Normally IMS plays the voicemail messages through the PC user's telephone. IMS can be set up to send the voicemail
messages as wav files which are played using the PC's sound capabilities. However, this creates a heavy load on the
network and servers and so is not recommended. Typically, one minute of speech requires the transfer of a 1MB file
across the network.
·Required Network and Exchange Server Knowledge
Installation of IMS requires access to the customer's Exchange server and to other critical components of their
network. The installation should be performed only by an installer with good knowledge of Exchange Server and
Microsoft network setup. The installation should also be performed only in conjunction with the customer's network
manager.
