Hi everyone,

I'm getting stuck with sending SMS-DELIVER via Sigtran.

1. Succesfully sending the sms text (92 character): "Quy khach co cuoc goi nho, he thong MCA se gui danh sach toi Quy khach trong it phut nua. Ca"

I think it is related to the length of the CPT_REQ but don't know exactly what it is. The total length of succedded packet is 294 bytes. Please help me if you have any experience. Thank you so much, I hereby attach the succedded pcap. Thanks a lot.
