# Resolve Blank OMNI-CHANNEL Dialer For Incoming Calls

This guide provides instructions on how to resolve an issue where an incoming call rings audibly, but the Omni-Channel dialler does not appear on the screen to allow you to answer it. Please note: You must adopt strict tab management to ensure correct behaviour moving forward.

**Problem:** You hear an incoming call ring, but the OMNI-CHANNEL dialler remains blank and fails to display, preventing you from answering the call.

**Resolution**

1. Check your browser site settings to allow notifications for your Salesforce domain. [Reset site permissions](/v1/docs/how-to-reset-site-settings-in-chrome) if necessary using this guide.
2. Log out of Salesforce completely.
3. Close all open browser windows and tabs, especially the separate Natterbox Webphone window.
4. [Clear your browser cache and cookies](/v1/docs/how-to-clear-a-cache) for ‘all time’.
5. Log back in.
6. Close completed VC record tabs immediately after you finish post-call tasks or ACW.
7. Manage multiple records using the sub-tabs built into the Salesforce console, rather than opening new browser tabs or leaving old VC tabs open indefinitely.
