Hi, I did not understood your sentence, can you re-clarify which Jabber phone you are using,
These are jabber different types of phones Cisco has;
1. Jabber for windows
2. Jabber Guest
3. Jabber for MAC
4. Jabber for IOS
5. Jabber for Android
Once you confirm which Jabber you are working and basis I can say whether its compatible or not?
BTW, I haven't seen any administrator OR user install Jabber on Windows Server OS.
