With Talkdesk, if your administrator has enabled custom outbound caller ID permissions, you can choose which phone number to display as the caller ID when making a call.
When this option is enabled, a dropdown menu is displayed, allowing you to select your desired outbound caller ID per call:
Once a phone number has been selected, it will be used for all your outbound calls until the outbound caller ID phone number is changed again, or the Default option is selected: in this case, Talkdesk automatically determines the best number to use based on the phone number you are calling.
