Services

To obtain needed credentials, you have two possibilities:

Use the Device tab (VoIP) and define the appropriate devices there (e. g. voicemail and echo). This way they will be able to authenticate and work as SIP clients. Recommended.
Create a system account for each, but it is not to handy (smart) to have them in the account list.

Note: You may face a warning message announcing that JAVA is not installed on your computer. It is needed for this service. In this case, download and install the latest JAVA 6 (or 7) Update from http://www.java.com.

Note: With 32-bit IceWarp Server, use 32-bit Java, with 64-bit one, use 64-bit Java. This is needed because Java registers its path only for the application with same bit architecture. Still you can register path to 32-bit Java app for 64-bit applications and it will work, only verify that the path c:\windows\syswow64\ is indeed in the system %path%. When you go download Java 64-bit, click the See all Java downloads at java.com and choose it manually. Or else, if your browser is 32-bit one, it will download the 32-bit version instead.

Figure. Java required but not installed.
