Best sip client!

The only sip client with push support! I also bought the g729 codec and 3G calls are crystal clear. Its not draining my iPad battery down a lot thanks to push. Even if the client is turned off I can still get calls. I have some caller ID issues on my outbound calls... I contacted support, we were unable to resolve this issue, but otherwise they have provided great support. VoIP is not made to be working with nat routers and 3G networks...,so results may vary. Now, I hope I wont have to pay for the iPad version and they will make it universal instead! Buy it now!
