Choosing table columns

Every list in the operator panel — calls, trunks, organisations, numbers, campaigns, the audit log — carries a Columns button above it, on the right, beside the search box. It shows how many columns are on out of how many exist, so a list that looks short says why without being opened. Tick a column to show it, untick it to hide it. The menu stays open while you work, because choosing columns is usually several decisions looked at together. Reset to default puts the list back to how it arrived.

​

What it remembers

Your choice is kept per list and per person, in the browser you made it in. It survives reloading and signing out, and it does not follow you to another computer or another browser. Two people using the same panel never change each other’s lists.

​

What you cannot hide

The column that says which row it is. On a call that is who spoke to whom; on a trunk, its name. Hiding it would leave a table of measurements belonging to nothing, so it is not offered. Hiding everything else is allowed and leaves that one column standing.

​

Columns that start hidden

Some columns are off until you ask for them — on Call history, the codec, whether the call was transcoded, the hangup cause and the AI tokens. They are the switch’s own diagnostics: exactly what you want when you are chasing a fault and noise on every other day. They are still on each call’s own page whether or not the column is on.

​

Columns you will not find

A column is missing from the menu entirely when the account may not see the figure behind it. Carrier cost and margin need margin:read; without it the API does not send them at all, so there is nothing a column could show. This is the same rule as everywhere else in FireTone: absent means not permitted, not applicable, or not known — never zero. Granting the permission makes the column appear in the menu.
