Hi, Hendrik ... Regard of what happened to you, for me, I prefer not to reply directly with the default sms-services, with text parameter [text="Sorry, bla.. bla... bla.."]. So, I process SMSes prior of answering the SMSes. To do this, I put max-messages=0, to prevent kannel's sms-service reply directly on incomming SMS. All SMS's response is sent to the sender by send-sms, after some processing step. You could discard or give "Sorry ..." response based on SMS processing result. In my opinion it would prevent the pingpong SMS that you described. Hope this could help... --tjatur > > > >> > > > > > >
