My SalesForce admin followed the integration guide for 3cx. We now that the call with 3cx button in SalesForce, but when the click on it they just get a browser error: http://localhost:47280/SalesforceAPI.aspx?UserAccountfirstname.lastname@example.org&Destination=(475)%20123-4567&LeadId=00Q4400001Pvg3U It's clear that the local 3cx client should be listening on port 47280, but it does not appear to be doing so. Did I miss a step in setting up the client? Is there a setting I should turn on? Thanks!
