When registering the server, the console kept printing "OM Collection Timer", there is no failure tips. The following is a print log, what is the reason? Is it in connection? Why can not connect? Please answer my doubts, thank you!

The CSDK components require to check system information. It happens every 1 minute for foreground mode and every 30 min for background. These logs will be added every time. It is required for debugging and it is regular behavior.

I get it. thank you! But I still have a question. Why did not I respond when I started registering a server? That is, there is no success nor failure.

Sorry for the delay with response.

From the provided logs it is unclear what happens. Is that the only log you have? Could you please share the full log for csdk.
It is also unclear whether you subscribe or not for registration events.
You can always refer to a documentation - https://www.devconnectprogram.com/site/global/products_resources/avaya_client_sdk/programming_docs/current/windows/communication/tech/initializing_sdk.gsp#creation-of-the-user-object-1780
Or check how it is done in sample app.
