I can rely upon the value of smpp.source_addr and smpp.destination_addr in
order to identify fragments that are potentially part of the same message. I
can create conversations based on smpp.source_addr and smpp.destination_addr
(both are NULL-terminated text strings that represent an endpoint's "phone
number") addresses (address.type = AT_NONE). The question is whether I can
reassemble Short Message fragments which are spread across distinct SMPP/TCP
connections. To summarize:
  TCP conversation t1 (SMPP conversation s1): SMS fragment 1/2 (smf1)
  TCP conversation t2 (SMPP conversation s1): SMS fragment 2/2 (smf2)
    ==> How can I reassemble smf1 and smf2
