asterisk users - Jan 2009 - If you use Realtime Extensions... READ THIS...

One of the frequently asked-for features in pbx_realtime is the ability not
to have to have an extensions.conf, because you want realtime to auto-register
its contexts.  There is now such a patch out there, for testing.  The faster
that people test it and give feedback, the sooner it can make its way into
Asterisk.
