Could Not Start Session with RingDNA Server



When a user attempts to log into the dialer or carry out an action in the dialer, a pop-up window displays advising the user that a session could not be established with the ringDNA server.


This generic error will display when our dialer encounters connectivity issues. Most commonly this is caused by a local network issue preventing access to ringDNA’s servers, or our carrier provider’s media and signaling servers. Similarly, users will also see this message in the unlikely event that ringDNA’s servers are offline or subject to some other calamity.


  • Check our Status page for advisories or system maintenance which may impact your access to the dialer.
  • Run a Network Test to ensure your computer is able to connect to our carrier network. Take note of any errors in the “Log Output” section and share with our Support team.
  • If you are connecting through a VPN or Proxy, try temporarily disabling it and try accessing the dialer again. Some companies require that domains are whitelisted before they can be accessed.
  • Clear your browser’s Cookies & Cache. There may be an expired browser cookie preventing successful authentication when logging you in.
