I am neither a lawyer or a licensing expert, but the basics are that if 
you make such a change for your own internal use, you are probably fine. 
Example: You have 10 sites with Asterisk in them and at each site you have 
someone in your company who has to log into the CLI and do stuff. You 
change the header to pass them a message. This is probably (not going to 
guarantee this) going to be fine as it is not something you are releasing 
out into the wild nor are you selling it and making a profit from it.

However, let's say you make a commercial project that uses Asterisk under 
the hood and you change the header to hide the fact that it uses Asterisk 
and that Digium has any ownership of the code. That would be not be okay 
in most, if not all cases.

Basically, the code is open source, but it is still owned by Digium and 
they have specific rights that you have to be careful of in regards to 
licensing. If someone outside of your organization will ever be running 
the code you change, there are specific rules that have to be followed, 
including those that relate to releasing your changes to the code and to 
giving credit back to those who wrote the code your code is based on.

Basically, Richard Kenner is spot on. If you are unclear, best to consult 
an attorney who specializes in this, especially if you are redistributing 
the altered code.
