Hicom reusing call ID

[joel]

The newest version of the Siemens Hicom 300 we have, is reusing CallID of previous calls. This means that new calls get attach data from old calls which is very bad.
This is clearly a Siemens problem and I saw in the Genesys ticket archive that 2 other customers had have this problem. It will take ages for our local Siemens administrator to solve the problem. Has anyone encoutered this problem and would anyone happen to know the name of the Siemens Patch or whatever that needs to be applied ?
