In the years I have been reading these forums, these are the kinds of questions that confuse me. If one is using FreePBX, you can easily add a trunk, unless things are broken badly.
Surely you have under Connectivity, Trunks is in the list in your FreePBX system?
Click Trunks and you should see a whole list of Add a Trunk.

I already try to search in google but I can’t find any result that explains what I need.
The whole point of FreePBX is to reduce the need for hand-editing the Asterisk config files, isn’t it? You could start helping to understand the issue, from sharing your FreePBX & Asterisk version, list modules installed, do you use the distro or install on a non-shmooze system (and which one)…
Also there is the Schmooze/Sangoma/FreePBX wiki, which probably has the answer to the question, which files are NOT touched by the FreePBX when reloaded.
The files that are modified by Freepbx have a note saying that.

Since FreePBX usually gives the user-editable files a _custom suffix, if you know which file to add the trunk to and how (on mine it is /etc/asterisk/sip-*.conf) look for one(s) with _custom suffix (
