Going to -> Show error notifications in help and show me error code: CJ:1000:101.

If the CUCM/IM&P/CUC certificates are not pushed to the device's certificate repository PRIOR to you trying to login, they will show up that notification until you accept it. The Jabber documentation has a whole chapter dedicated to certificates, and this is discussed.

you need to either use a public CA. Or your own CA. The certificates need have the FQDN of the servers. Then you will not receive errors.
