USSD: Mallformed destination_addr `(null)', may not be empty. Discarding MO message

Hi Team,

I have been very successful in using kannel (with binds to SMSC) to deliver MT messages to handsets.

I have just been given a project that involves receiving MO messages from a USSD gateway and I am getting the Error above.

When I send *300# from the phone, I get "USSDC: Rejected by ESME" back on the phone.

Attached to this mail is the complete error from my log and my kannel config (Kannel bearerbox version `svn-r4979M')

Kindly assist to check where this error is coming from and if I am doing something wrong.

Thank you
 
Best Regards,
Kayode
