TRUNK NAME - PLEASE a simple question for YOU ALL!

I have upgraded my pbx to 2.8
Now I have to add another trunk and modify that in my custom contest.
But I don’t find the real name of that trunk.
PLEASE someone knows where this version save that informations ?
Thanks a lot

new version is not always the best!
you should specify your trunk information first, it’s sip trunk or ZAP trunk

I’m speaking about a ZAP Trunk
