Sorry if I rant, but that is not correct, and it is one of the common
misperceptions that makes people not want to contribute back to open
source projects.  Digium does NOT have a copyright on the codebase.
Code contributed to Asterisk is copyright by the ORIGINAL AUTHOR, unless
that author chooses to release it into the public domain (thus expiring
copyright) or to assign the copyright to Digium.  Digium gets a
disclaimer stating that they are free to use that code with no
restrictions, but unless the author specifically assigns his copyright
to Digium, Digium does NOT have copyright on contributed code.

For a very clear example, take a look at apps/app_sayunixtime.c, for
which I own the copyright (though I've released it with no restrictions
on usage).
