In previous blog entries, I have discussed how to configure the Jabber client without using the IM. In this blog, I want to discuss the opposite way i.e. configure IM only Jabber client (even without the LDAP).
Basically, it’s quite straight forward, just follow the 3 steps below:

1. Configure end user in CUCM
2. Start the Jabber to connect to the IM server
3. Add local contact

Step 1. Configure end user in CUCM

Under CUCM, navigate to User Management > End User. Add or edit enend user, Check the Enable User for Unified CM IM and Presence field, and also add the user to Standard CCM End Users if not yet added.

Step 2. Start the Jabber to connect to the IM server

Now run your Jabber as shown below (you maybe asked to reset the Jabber, also if you are not using DNS, you need to add the CUCM in the local host file of your PC, please refer to this blog):

Step 3. Add local contact (if not using LDAP)

Now after login your Jabber, under the Setting > File > New > Custom contact to add a new local contact. The most important is the Chat (IM address), the username part is the other End User ID configured under CUCM, while the domain is the domain configured under the IM&P server:

You can add it to any group.

Then you should be able to chat with the other user.
