Failed.  I checked the online docs and the syntax seems to be correct
but I get this:

[Aug 31 21:52:00] WARNING[-1][C-0001fed5] pbx.c: No application
'ExecIf' for extension (unauthenticated, 5555551111, 3)

Is there a module that I need to load?

In case it matters I am running Asterisk 11.23.0 on NetBSD 7.0.
