* The GPLv2 places no restrictions on what you can 'write', it only
places restrictions on your distribution of things that you write
that could be considered 'derivative works' of a GPLv2-covered work
(in this case, Asterisk). If you write something that could be
considered a derivative work, and you wish to distribute it, then
the GPLv2 obligates you to distribute that work under the GPLv2 or a
compatible license.

Minor nitpick: a derivative of a GPLv2 work can only be released under
the GPLv2, or a licence so similar to GPLv2 as to be indistinguishable
from it.  You cannot distribute a GPLv2 derived work under, e.g. a BSD
or Artistic licence.

This is strictly true, but of course any decisions to allow or disallow distribution of a derived work are made by the party(ies) who distributed the original work under the GPLv2; if they choose to allow distribution under more permissive licenses, they can certainly do so.
