Tony guan 03:05, 6 September 2006 (UTC): Q1: I think this design should be closely combined with the hardware button design. Some feature can be called or completed by directly press the hardware buttons. For example, call the history, or call directly from the current input by pressing the green call button. such as the nokia cell phones.
Alex Q: In old specification (Call Handler Application Specification v0.2), there is another mode called "In Call", both of the Incoming and Outgoing mode will switch to "In Call Mode" after taken some action. However, call handler application is not listed in the Application Page now. Does this mode won't need any more or there will be other countermeasures? Thanks.
