We need to know if it is possible to customize the graphical interface of an open source softphone written in c++.

So the project consist in analysis the softphone sources and customizing it to change the look...in order to fit some customers wishes (eg for coca cola change the look to a bottle of coke..)

The chosen softphone is sipxezphone and the opensource web site is there http://sipx-wiki.calivia.com/index.php/SipXezPhone_Introduction_and_Sc
reenshot

You can download the sources there.

The goal is to keep all features as it and to change the look.

The deliverable must be the result of the analysis : an explanation of what has to be changed (wich modules) the average cost per change and a little example with the design of a coke bottle.
