Zaptel Trunk & FreePBX panel

I can make outgoing call from my SIP soft phone to my ZapTrunk (E1) but that trunk do not appears in freePBX Panel (FOP ?).

Other trunk ( Gateway Custom trunk ) appears as soon as I create it.

Does someone knows why ???
I use trixbox.

A temporary work around would be to add the trunk manually to /val/www/html/panel/op_buttons_additional.cfg. Just copy the format of the custom trunk and change the appropriate settings.
