Of course, it's open source.

Please do further development and contribute it back to the community!
As long as you are using it yourself, you don't have to pay a license.

If you *sell* Asterisk with your own additions, you either have to
give the source code of your additions away to the buyer under the GPL 
license and he can do whatever he wants to do with it - or buy a 
commercial license from Digium and thus get the commercial rights to the 
software and the right to sell your customized version.

Regarding prices for that, contact Digium sales.
