having jabber running on windows without a csf?

[baselzind]

i have a user with cucm 10.5 with imp running jabber on his win 10 without having a csf created for him? how is that possible?

[Jonathan Schulenberg · Accepted solution]

Sure. The CSF device is only relevant to the softphone functionality of Jabber. The IM&P functionality is not dependent on the CSF device.

[baselzind]

you mean if the user is on IMP he can log in to jabber but without softphone functionality?

[Jonathan Schulenberg]

Yep

This is explained in the Jabber documentation, and has been an option for quite some time

On-Premises Deployment

An on-premises deployment is one in which you set up, manage, and maintain all services on your corporate network.

You can deploy Cisco Jabber in the following modes:

• Full UC—To deploy full UC mode, enable instant messaging and presence capabilities, provision voicemail and conferencing capabilities, and provision users with devices for audio and video.

• IM-Only—To deploy IM-only mode, enable instant messaging and presence capabilities. Do not provision users with devices.

• Phone-Only Mode—In Phone-Only mode, the user's primary authentication is to Cisco Unified Communications Manager. To deploy phone-only mode, provision users with devices for audio and video capabilities. You can also provision users with additional services such as voicemail.

12.0 also added Phone Mode with Contacts Deployment
