    Hi, Our new 3CX Server (v12 with sp6; .net framework 4.5.1; Windows Update up-to-date; Windows server 2008 R2 Enterprise) had below issue twice in a week:
    All 3CX Window Clients display 'NOT CONNECTED' under 3CXPhone mode, Looks connected under CTI mode but the Queue option and Availability option are all greyed out , IP Phones were working fine. Checked '3CXPhone Clients' and 'Server Event Log' attribute, the windows clients are all registered in the server. We tried to recycle Application Pool or restart IIS service, did not have any luck. Then restarted the 3CX PhoneSystem service which rectify the issue. There is no obvious error message from window application log and system log, Server Event Log and Server Activity Log all look normal. Since We are using the server for a contact centre environment, we could not have enough time to test which particular service cause this issue by interrupting the operations, and the issue really cause trouble because we need the Windows Client to trigger screen popout for particular software. Please advise.

    Hi,
    Our experience with this problem is that it is usually caused with anti-virus software particularly AVG. You can work around it by creating exceptions. There is an article on 3CX site on how to prevent this problem here http://www.3cx.com/blog/docs/3cxphone-presence-self-help/

    Thanks a lot for the reply mate, this issue has happened 3 time in last month, There is no firewall setting against the access to 3cx server on PCs, Proxy exception has also been added. Once restart 3CX phonesystem service, client will be reconnected. I would keep monitoring the issue, please advise if we have any other clue, please advise ;).
