Sorry I dont respond fast, and thanks alot for all help.

I make a copy of default CoTurn ports directory (4.9.0-r0) and put whole patch (your newest to 4.16.0-r0) in a file in main directory, Then run "patch -p0 < coturn.patch" and get:

......
Patching file patches/patch-src_apps_relay_mainrelay_c using Plan A...
Hunk #1 succeeded at 1.
Hunk #2 failed at 12.
1 out of 2 hunks failed--saving rejects to patches/patch-src_apps_relay_mainrelay_c.rej
......

All rest files in patch succeed. Sorry I dont understand how I can fix it. I attach to the mail the ".rej" file if it helps.
