Do you want to NOT use your SIM minutes? Do you have a SIP or a Skype account? If yes, then: 1. configure your Google voice to add your SIP or Skype phone number 2. Enable call ID on your SIP/Skype account. This means if you use your SIP account to call someone, that person will be able to see your SIP number and not "unidentified". 3. Restart qgvdial so that it picks up the SIP/Skype number from your Google Voice settings. 4. Set up your SIP/Skype account on your N900 5. Select the SIP account inside qgvdial - either call back or call out. 6. Dial out from qgvdial and it will use the SIP account you selected. 7. No more SIM minutes needed! This is the way I used qgvdial on my n900 for quite some time.
