It just depends on what codec is being established with the upstream carrier, the VOIPo device is relaying that it can handle G711 and G729. We do this as a higher number of your international calls will be G729, so without it more international calls would fail in some scenarios. Other than this most of your domestic calling will be negotiated at G711. However again it depends on who or where the call is going.
