That description seems very unclear to me, but it could be a language
problem since you're not talking clear and straight Swedish here.

We do have an incoming channel. This channel enters the dialplan
in a preset context where we match the extension with the dialled  
identifier - a number
or in the case of SIP a string.

During execution of the dialplan for the incoming channel a lot of  
things can happen,
we can jump to other parts of the dialplan within the same context or  
in another
context, we can place outbound calls or play stuff.

During an outbound call, nothing happens in the dialplan. During a  
dial, the channel
that executes the dial stands still from a dialplan point of view.

"During a call" is very unspecific in regards to writing  
documentation for asterisk,
it's hard to grasp - do you mean "a call" when two or more people  
have an audio
communication path - or from the point an incoming channel started  
execution of
the dialplan until we hangup the incoming channel and produce a cdr?
