I have Sipdroid and Googlevoice installed on my tablet for free IP calls. It works fairly well, but I am having a hard time dialing directly from my contacts. I found this entry http://forum.xda-developers.com/showthread.php?t=1802854 that describes and solves the same problem I'm having, but on a different device. I tried using the phone.apk they posted, but it force closes endlessly. Anyone have any ideas how to get this working 100% on our tablets?
