GANC

I was Googling open source GANC and came across you web page: http://openbsc.osmocom.org/trac/wiki/osmo-ganc I am interested in learning how to program handsets to work with a GANC controller. Because I am new at this, I am not sure if it is possible to add this functionality to an existing platform and would like to learn more about existing implementations. Is there a good resource (code examples) to look view? Thank you. Raymond SMS: (703)828-7168 raymond.m.chiu.(a)gmail.com
