config.js

     // will open an etherpad document.
     // etherpad_base: 'https://your-etherpad-installati.on/p/',
 
+    // To enable information about dial-in access to meetings you need to provide
+    // dialInNumbersUrl and dialInConfCodeUrl.
+    // dialInNumbersUrl returns a json array of numbers that can be used for dial-in.
+    // {"countryCode":"US","tollFree":false,"formattedNumber":"+1 123-456-7890"}
+    // dialInConfCodeUrl is the conference mapper converting a meeting id to a PIN used for dial-in
+    // or the other way around (more info in resources/cloud-api.swagger)
+    //
+    // For JaaS customers the default values are:
+    // dialInNumbersUrl: 'https://conference-mapper.jitsi.net/v1/access/dids',
+    // dialInConfCodeUrl: 'https://conference-mapper.jitsi.net/v1/access',
+    //
