I've a bit weird problem. I'm setting up a lab to test Jabber. Jabber for Windows logins when pointed to Presence server and registers as a softphone as well and works normally.

But when try to be pointed it to the CUCM to register in Phone mode only it shows the error message "Cannot communicate with the server".

Any Ideas?

Thanks.
