Change name in recordings

I need to change the name of the recordings that Free-PBX generates, I need to add the destination or ${EXTEN}, I can do it using the vi editor, but once I reload all the changes are lost.
can you help me?

Your post makes no sense. Please repost with relevant information as to what you are editing and why . FreePBX generates no recordings.

ok, excuse me, my english is quite bad.
I need to change the name of the recordings
the format currently used is the default, I need to add the destination
NOW : OUT11899-20121026-163235-1351279951.76.wav (example)
NEED: OUT11899-20121026-163235-1351279951.76-destination number.wav

I did it editing the file extensions_additional.conf, but every time I reload, I lose all the changes.
once again sorry for my bad english

If you look at that file it says at the top very specifically

; Do NOT edit this file as it is auto-generated by FreePBX. All modifications to ;
; this file must be done via the web gui. There are alternative files to make ;
; custom modifications, details at: ;

this is why you can’t edit it and expect the changes to be permenant

as self documented

will further help. PLEASE spend a few minutes in the “Documentation” links at the right and at the bottom of this page, all will be revealed to you and you won’t have to ask these already answered questions again.

I know that we 're not supposed to modify that file, that’s why I’m asking here the right way to do it.
is possible? I spend a few hours looking through forums and I couldn’t find the answer.

I am confused as to why

does not explain it to you. It answers every one else’s questions, just concentrate on the bits that say “custom”

I don’t know exactly what is the process of changing change the name of the recordings that Free-PBX generates. You can ask to any specialist. Thanks
