Actually, our end goal is to support TS 124 390 or at least get close
enough to it. When we discussed integration of SIP into OsmoNITB there
was a strong opposition from you and Harald, so we were looking for
the best way to export required functionality from OsmoNITB to avoid
adding SIP into the OsmoNITB itself. Within this logic SMPP just adds
overhead and extra complexity without offering any benefits.
