Hello, dear support community.
I have CUCM, IMP 10.5 installed. SSO is configured.
A couple of users complain that for some reason their jabber clients pop-up a notification about certificate for idbroker.webex.com with possible actions, - accept, decline and show the certificate (as it is usual when a certificate is untrusted). It is issued by HydrantID SSL ICA G2.
Just too accept this cert and forget about this for the next logins is not a big deal.
However, I didn't configure any external connections to webex or other cloud services.
That is why my concerns are why some of jabber clients try to connect idbroker.webex.com ?
and how do prevent/disable it ?
Service Profile is configured only with local services (CTI, IMP, Directory) but it is not assigned to any users.
jabber-config file is almost empty:
<config version="1.0"> <Client> <Persistent_Chat_Enabled>true</Persistent_Chat_Enabled> </Client> <Directory> <DirectoryServerType>UDS</DirectoryServerType> </Directory> <Policies> <Disallowed_File_Transfer_Types>.exe;.msi</Disallowed_File_Transfer_Types> <EnableSIPURIDialling>true</EnableSIPURIDialling> </Policies> </config>
Solved! Go to Solution.
You are right - I have already disabled EXCLUDED_SERVICES=WEBEX and it helped.
However, it is odd a little bit, because only several jabber clients faced this exactly request during jabber initiation. DNS and version of jabber are the same for any working stations within a company.
Why do you think others didn't experience the same behavior ?
My only guess is those clients’ operating system (ie Windows, macOS, etc) did not trust the issuing Certificate Authority for some reason.
