Usage Hints

Check that configuration default values meet your needs (touch item titles for help).
Then create one or more accounts (again touch item titles for help).
Peers of calls and messages can be added to contacts by long touches.
Long touches can also be used to remove calls, chats, messages, and contacts.
You can re-reselect the previous call party by touching the call icon when Callee is empty.
If you cannot hear the other party of a call, try to increase Media volume.
