If you have multiple phone lines, you can change the active line for calling.

Select Connect to a Device and select your phone from one of the Personal Devices choices.


 

If you're connected to your desk phone but want to call using Webex instead, click and then select My Computer before dialing.

If you want to create a custom name for your desk phone, you can access the description of your desk phone and you can personalize that description to something that makes sense to you. Hover over the phone description and then click edit to change the name. If you have more than one desk phone connected to your app, customizing each description can be helpful.
