Hi All, I'm having problems with Kannel 1.4.0 and certain messages which arrive from one of the telcos we connect to.
The messages are arriving with the UDHI set even though there is no UDH.
The first Character of the text in these messages is C which is
therefore getting treated as the length of the UDH so we end up with the
error:
2005-07-15 10:50:59 [32384] [7] ERROR: SMPP[voda_nz_1]: Mallformed UDH
length indicator 0x044 while message length 0x003. Discarding MO
message.
We never received that error with kannel 1.3.2. Would it have been
silenty dropping the messages or ignoring the UDHI option? If the
latter is there any way I can tell kannel 1.4.0 to do the same as the
telco is saying its a handset issue and out of their hands?
Thanks
Stuart
