Description

See attached pcap file:

  • MS sends CP-DATA (RP-DATA) using BSSAP.DLCI.SAPI=3 (SMS)
  • MSC responds with CP-ACK (and other messages) using BSSAP.DLCI.SAPI=0 (RR/MM/CC)

this is clearly wrong. SMS related communication always happens on SAPI3

Can be reproduced with upcoming MSC_Tests.TC_lu_and_mo_sms
