I'm trying to get OpenBTS to send a binary SMS and return a delivery
I have managed to create the UDH data using a BitVector passed into a
TLUserData and it looks like the binary SMS is being pumped out and
received by the device.
I have set the reply path (RP) and status report indication (SRI) flags
and I've checked 03.40 annex D.
The only message I get back is always an RP-ERROR though with the
content "Cause: (96) Invalid mandatory information". I have read that
this could be because the service centre address is in the incorrect
format. I have tried national and international and also setting X.121
I've uploaded a pcap here in case this rings a bell with anyone on the list:
Any insight much appreciated.
