If you use one of the latest (K)Ubuntu versions with the NetworkManager and no connection is active (e.g. the NetworkManager is in 'offline' mode or no network connection is found) Ekiga shows error message(s) that the Listeners for SIP or H.323 protocols can't be activated. Ekiga also shows these messages if another program blocks the ports.
This is really bad for the work flow - if you are starting the computer, and no network connection is established (or is establishing - which takes a few seconds) Ekiga should not show these messages. Instead it should show an icon in the panel that indicates that the Listeners couldn't be activated.
Additional, it should check every N seconds if it can start the Listeners.

The optimal behaviour would be:
- Ekiga listens to the NetworkManager and creates the Listeners as soon as the network is ready (and destroys the Listeners as soon as the network is down).
- No error messages are shown - instead, an icon in the panel indicates the connection status.

This would be much better for the work flow.
