Bug: .Net 3CXPhone API: After Update to V15.5 we get no events (OnCallStatusChange) in CTI Mode?

[Franz Nussbaumer]

Hallo,
this configuration with 2 instances of 3CXPhone worked perfectly with versions 10.x to 12.x after Update to version 15.5 we get no events (OnCallStatusChange) when the 3CX Phone is in "CTI" Mode!?
What has been changed here? I think this is a Bug.

Explanation:
1. We dont have Hardphones
2. All our users have an Office Terminalserver Session with CRM Client with plugin and 3CXPhone in CTI mode for outbound and inbound Calls.
3. All our users have an Working computer 3CXPhone in softphone mode with Jabra Headset
I hope you can understand that we do not change this configuration. The question is why did the behavior change with version 15.5?

Today i have Test it with the TAPI Multiline Integration. It has the same behavior.

Thanks for Help.

Hello @Franz Nussbaumer,

As mentioned in the other thread, I think that the problem is that you're using 2 instances of 3CXPhone for Windows, one in CTI mode and one in softphone mode. I would recommend you to check what happens if you use a different softphone, for example the 3CXPhone v6 which you can download for free from here:
https://www.3cx.com/downloads/3CXPhone6.msi

Also, please check that you have a PRO license key, because this API is only available for PRO licenses.

Kind regards.
