Why do I hear a busy tone when trying to make outgoing calls?
Posted by - NA - on 14 November 2008 09:44 AM
When you hear a busy tone when trying to place an outgoing call, the problem may be related to your adapter being unable to register with VOIPo. VOIPo will be unable to route any outgoing calls if your phone adapter is unable to register. This is why you end up hearing a fast busy signal.

Please follow the following steps if you are unable to make outgoing calls:
  1. Verify that you are connected to the internet
  2. Check your firewall settings on your router (if one's applicable)
  3. Power cycle your modem, router (if one's applied to your network), and adapter.

If your problem still persists please contact support toll free at 877-99-VOIPO or via email at
