help | 3 Configuring the Contact CRM integration | Answer/Hangup button
3.1 Answer/Hangup button
You can configure up to 4 buttons in the Bubble pop-up notification. You can create buttons for CRM-ERP specific actions like showing contact information, sending an email, sending a WhatsApp message, opening a search bar, etc.
In addition to these buttons, the Contact CRM integration provides the option to enable a Call Control button. When this feature is enabled, the user will have a button in the Bubble pop-up notification to answer or hang up the call.

The Answer button is only supported when Softphone is selected as the primary phone and will not work when a fixed or mobile phone is selected.
