At first glance this looks good.  Please describe the testing you have done in a little more detail.  Before committing, I would like to take a deeper look at this and get a few more eyes on it.  Good work.

> I added debug information for a better understanding on how the parsing is actually done (shows each SDP line parsed with OK or UNSUPPORTED).
