As integration was developed based on older version, I suggest you to test if it works with 3CX Phone System version 15.5.
Also, you could ask other partners. Might be they have customers using this version.
Clients have their own cache, and then the server has the shared cache, if you want it kind of black and white.
Presense should be there as far as i know...
Hello Paul,
That is something only HansaWorld can do. But that would help to understand is that causing the problem and - if so - we fix the issue.
Additional information is appreciated.
Yavuz...
