Where is the outgoing limit limit stored in freepbx, in the database?

Question

linux

Good afternoon
Tell me, please, where FreePbx stores the setting of the extension number "Restriction in simultaneous outgoing"?

found many settings in the MySql database, but I did not find this one - apparently, freepbx stores the "Limit on simultaneous outgoing" setting in a file or other storage.
