Client authentication in Collaboration Edge/ MRA

[baktha.muralidharan]

Hello

Could someone help with the following question?

In the process of a Jabber device on the Internet registering with CUCM, when does the Jabber client get authenticated? 

My understanding is that when a Jabber device on the Internet accesses (to log on to CUP)  the expressway-E,  only the server (Expressway-E) is authenticated (using the public CA certificate in the Jabber device). Is this correct?  If yes, does the Jabber device/user get authenticated when the device attempts to register with the CUCM  ?

Thanks in advance,

The thing is CUCM and CUP are authenticated by using their CAs, when Jabber login by MRA. However the Jabbber itself seams not be authenticated, only the user is authenticated through UDS or LDAP.
