Thanks.  I like to keep devices and extensions separate, for security reasons, and it's a
pain having to define the association in different places, especially when sip.conf seems
like the logical place to do this.  Do you think if I were to code up a function like
AUTOREG([context,]exten) that returned 1 for auto-registered extensions, 0 otherwise, and
set a channel variable to the registering device name, it might be useful enough to be
accepted as a feature?
