In short
Groundwire is a voip app for Android created by Acrobits, s.r.o. And this is a perfect way to solve bug.
Highlights
The support team helped me very quickly to solve a bug
The best sip client for Android
Works well on Samsung Galaxy Note II
This is though the best SIP client out there
This is the best voip application that I ever used
Conference call and call forward
Particularly happy that this has ZRTP support
But it has the best support
Thank you for push notification Clear voice call
The latest version crashes when making a GSM call
Does not offer a intuitive way to look up a contact
As I don't use ZRTP nor G Push notifications save battery
Like deleting a SIP account
On the road and updated this app to find it lost all my SIP settings
Can't get this app to work with 007voip
Does not integrate with the phone's normal phone functionality
I can't pick it up using the headset button
It still tries to handle native outgoing calls and force closes
Have to uninstall to stop working
