Trying many things to get voip/sip in order to be able to call from Paladin,so far no luck. I saw that a user was able to use jphone lite on Paladin and would love to hear how it was done.If csipsimple can be used would like to know to set it up.Fellow Paladin owner or Skype please save us!
I'm using CSipSimple on Paladin. After you install MIPS nightly build it works the same way as on any other android device. If you need help with setup for your particular VoIP provider - ask in csipsimple-users group.
JPhoneLite also works (at least for outgoing calls) but UI is crappy and it does not remember server settings so you have to set it up every time you start app.
