extentions_overrride_freepbx.conf is not working

Hi, I´m using FreePBX 2.3.1.6, Asterisk 1.4.19 and Elastix 1.1-7. I´m trying to
customize the macro-dialout-trunk code. I already put my macro-dialout-trunk code in
extentions_overrride_freepbx.conf, but always Asterisk takes the extentions.conf
version.
What may be happening?
Thanks in advance
Carlos

after adding it to the file did you reload? In the asterisk cli type reload.

Also I don’t have a FreePBX 2.3 build any more, but check the top of the extensions.conf file to be sure it is including that file otherwise that would be a good reason why not.
