i m working on SMPP. till now v were to send message of total 160 characters.now v want to add an option of concatenation to it, in which if a message exceeds total of 160 charcters of length than that message should be send in two parts.for doing this we set three parameters which are 1)sar_msg_ref_num, 2)sar_gegment_seqnum 3)sar_total_segments.
Now i m facing problem in setting these parameters. Can any one help me solving my issue as this is really important.
