The most common issue users have with browser calling is granting microphone permissions. This is the error that appears when microphone permissions are not granted:
Fixing Microphone Permissions
To fix this issue, click the site information icon at the left end of the address bar. In current versions of Chrome this is the "tune" icon (it looks like a small set of sliders) — it replaced the older lock icon, so if you're looking for a padlock, you won't find one. In the panel that opens, turn on the Microphone toggle.
If you do not see the microphone option, or if you are still having issues, click the Site settings option at the bottom of the panel to open the complete permission list for ProLine.
On the Site settings page, use the dropdowns to set Microphone to Allow and Sound to Allow or Automatic. Sound should be set to Automatic by default, which should work fine, but if you continue to have sound-related issues, switch to Allow.
Note: These instructions are for Chrome. Safari and Edge may look slightly different, but the same general steps still apply.
Clearing Cookies & Cache
If you continue to have issues with ProLine's browser calling, try clearing site cookies and resetting the cache. Click the site information (tune) icon again at the left of the address bar, then click Cookies and site data. Then click Manage on-device site data, which should open this modal:
Click the trash icon on all items, and then click "done." You will be logged out of ProLine.
Close your browser completely, and then start it up again and login to ProLine.
Contacting Support
If you are still having issues with browser calling, click the hamburger menu (☰) in the top-left corner, select Account Settings, and then go to the Phone tab.
Go to Browser Calling Status and click Show Status. Copy the text in the pop-up.
Open the support chat inside of ProLine (or draft an email to support@proline.app). Include a description of what's going on with your browser calling, along with the Browser Calling Status text you copied.
