We’re running an older installation of Elastix at my office, version 2.0.0 (release 58) on top of freePBX version 2.7.0 (release 10). The call trace feature was bothering me. This feature is mapped to the *69 feature code as is common with many LECs in North America. In the default implementation you hear an announcement about the number of the last incoming call, and can then optionally press the “1” key to call the party back. I was frequently annoyed with having to wait for the IVR attendant to finish announcing the number of my last incoming call, I couldn’t interrupt the announcement without waiting for her to finish. Seemed pretty clear that I needed to replace Playback() with Background() some place.
Here is a video showing the original behavior, and the modified behavior.
Inside of /etc/asterisk/extensions_additional.conf is a context for [app-calltrace-perform]. Originally I made the correction in there, completely ignoring the header comment that read “Do NOT edit this file as it is auto-generated by FreePBX”. This worked, for a little bit, until changes were made and applied in the Elastix web interface, and then as promised the config was overwritten by a new auto-generated configuration.
It appears the correct place to add this is in /etc/asterisk/extensions_override_freepbx.conf
I appended the following lines to the end of extensions_override_freepbx.conf to accomplish the desired change.
When done, save the file and reload the dialplan
This all comes from Elastix (well technically FreePBX I think) other than the replacement of Playback() with Background() during the playback of info-about-last-call.gsm. Of course I also had to move Set(lastcaller..) and stuff above Background() since we can now jump straight to exten => 1,1 without having those variables set.
I’m not sure if this has changed in later versions of Elastix 2.x. I have to assume this annoys other people as well, but maybe it’s just me. If you have anything to add let me know in the comments.
