I doubt they'd have Ric or Sedol..? Those are also subscription based on the source side, which I haven't seen mentioned in IB..? I believe the SecIdList is populated with what's available regardless, and CUSIP is the only optional one subscription dependent.
As for support, calling is unlikely to be useful. The people who can answer these questions aren't ones you can call unless your account has 9+ digits in the balance.??
