In GSM MAP v1 and v2, there is only ForwardSM signaling(op-code is 46). Since
MAP v3, the ForwardSM signaling is divided into MO-ForwardSM(op-code is 46) and
MT-ForwardSM(op-code is 44).
In the attachment, the ForwardSM signaling is recognized as MO-ForwardSM, but
actually, it is a MT ForwardSM signaling.
