Release a phone line an AI employee still holds from before lines were shared (an id from getEmployee legacyPhoneLines). It cannot be attached back, since lines are no longer assigned to employees: it stops answering calls to that number and no longer takes on new people who text it. Refused when the line is not on this employee. On an employee that is switched on it takes effect on its next run: needs their yes; a card’s counts.

Variables

The example sends only what the schema requires. Some operations also need one of several optional variables (one filter or another, say); the description above says which.

employeeIdID!required
phoneLineIdID!required

Response

What comes back under data: a list shows as one entry, and a value as its type.
