Anyone using a paid VoIP service in their Android Tablets? I'm not talking about Google Voice or Skype, I mean like those regular paid VoIP like Vonage. Not sure if you can extract your VoIP credentilas from Vonage but the one I use from Onesuite can be use on most softphones, ATA's or even IP Phones. So an Android softphone is all I need if I can find a reliable one. Some say SIPDroid isn't compatible on all Droid devices.
