At TelHarbor the phone, chat and remote support only work when the secure connection is active. This is a security decision: if the tunnel is not up, the app does not register the extension and does not let you dial.

What to do:
1. Open the app and check the secure connection indicator.
2. If it is off, press it to connect and wait a few seconds.
3. If it does not connect, check that your Internet is working and that you are not on a network that blocks the connection, such as hotel or airport Wi-Fi.
4. Close the app and open it again if the indicator does not change.

From version 0.11 on, the app reconnects by itself when the network drops and comes back. If your computer has an earlier version, ask your administrator to update it.

If you work from a corporate network that filters traffic, your administrator has to allow the VPN traffic out. Your administrator or the TelHarbor NOC will tell you what to open.
