If you encounter problems with ARA and Geoport check the following settings:
* Express Modem Control Panel
- Turn Express Modem switch ON
- Modem Port is set to use External Modem
* Speech Setup Control Panel
- Turn Speech recognition OFF
* Remote Access Setup Control Panel
- Modem type is set to GeoPort Telecom

If, after checking all of these settings, it still does not work, do the following:

2) Turn virtual memory off
3) Turn file sharing off
4) Reset PRAM (Command-option-P-R at startup)
