Hi,
I am trying to use kannel for integrating with USSD GW using SMPP. My bind to USSD GW is ok. MO is ok and MT has some problem, msg is receiving in handset but if I send or cancel msg, it is is re-sending the same msg to my handset repetitively. I am using following parameters in kannel.conf without smpp-tlv group. # SMS SERVICE group = sms-service keyword = default omit-empty = true max-messages = 10 get-url = "http://X.X.X.X/abc.php?mob=%p&text=TRIAL&meta-data=%3Fsmpp%3Fussd%5Fservice%5Fop%3D17%26its%5Fsession%5Finfo%3D0"; name="*2210#" Do I need to define smpp-tlv group in my configuration? As per my wireshark trace, delivery_sm has optional parameters: ussd_service_op and its_session_info (attached) but submit_sm does not have optional parameters set. Do I need to set this parameter, if yes how to send these parameters in submit_sm? I am using kannel 1.4.4 in centos 6. Thanking you in advance. KABIN
