The call-info event type is handled by the sca module. The functionality's similar to BLA ("dialog;sla"), though the SCA event package comes from an old Broadsoft spec that a number of vendors support. Polycoms work well with it, as should Grandstream handsets supporting SCA. I don't know if the ATAs are capable of it, though.
