You may be intrested in this, How to set VM Lite as a service. I have not tested this with Version 1.4 or 2.0
Requirements (tested version)
• Avaya IP Office Telephone System (IP403 - 1.3.1 Admin CD)
• PC to run software (Compaq EVO D310v)
• Windows NT/2000/XP (Windows NT Professional)
• VoiceMail Lite (as with the 1.3.1 Management software CD)
• SRVANY.EXE (available from Microsoft, FOC)
Firstly you’ll need the srvany.exe from the Microsoft NT Resource Kit – I don’t think this application has changed much since NT3.51 and I’ve got it working on W2K with no problems. It can be downloaded it from here: ftp://ftp.microsoft.com/bussys/winnt/winnt-public/reskit/nt40/i386/srvany_x86.exe
Full documentation for SRVANY is included with the file and also on the Windows 2000 Resource Kit, but I couldn’t find where it has installed it on my PC, so I downloaded the SRVANY from the above site.
VMLite Run-as-service instructions
1. Firstly, install VM Lite on the target PC. (all the examples assume that it’s installed in the default directory and Windows 2000 is installed in C:\WINNT)
2. Copy the svrany.exe file to c:\winnt\system32
3. Install the svrany service using the following command: instsrv VoiceMail c:\winnt\system32\srvany.exe (instsrv is also included in the Resource kit)
4. This will create a new service called VoiceMail
5. We now need to edit the registry to tell srvany.exe which application to run. Either import the VOICEMAIL.REG file later in this document (and go to step 8), or start: regedit
6. Go to the following tree: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VoiceMail
7. And create a new subkey called “Parameters” in which you create an entry called “Application” which has a data type of REG_SZ which has "C:\Program Files\Avaya\IP Office\Voicemail Server\vmlite.exe" as it’s data (no need for quotes in any of the above)
8. Now go to services via control panel and ensure that the VoiceMail service has the following set: Start Automatically, Use System account, DO NOT interact with the desktop.
9. Start the service and test!!
That’s it – quite easy (as all things are when you’ve got them working). I had an older version of VoiceMail that kept popping error messages on the PC, but I had the service interact with the desktop, so you may want to enable that for debugging.
