So I found it in the code. Seems that you're right in that empty response + omit-empty = true is all that's required.... I'm not sure why it doesn't work for me, but ill debug it and see.
Thanks. /* * Empty message? Two alternatives have to be handled: * a) it's a HTTP sms-service reply: either ignore it or * substitute the "empty" warning defined * b) it's a sendsms HTTP interface call: leave the message empty */ if (octstr_len(msg->sms.msgdata) == 0 && msg->sms.sms_type == mt_reply) { if (trans != NULL && urltrans_omit_empty(trans)) return 0; else msg->sms.msgdata = octstr_duplicate(reply_emptymessage); } ________________________________ From: Brian McCavour <bmccav...@yahoo.com> To: Rene Kluwen <rene.klu...@chimit.nl>; "users@kannel.org" <users@kannel.org> Sent: Tuesday, January 15, 2013 3:52:18 PM Subject: Re: block sms-service response to bearerbox That's what I tried first, but I then get a msg sent to bearerbox with "Could not fetch content, sorry."

Basically I am seeing (not sure about 1-2 of the ack orders but in general...): 1 - request to smsc 2 - smsc sends to smsbox 3 - smsbox send ack back to smsc 4 - smsbox sends sms-service request out 5 - service sends response to smsbox 6 - smsbox sends body or default text to smsc 7 - smsc sends ack to smsbox 8 - smsc sned-url pushes reponse For some srvices though, there should be no sms sent based on the response. So these steps 6,7,8 should be prevented. Is there a clean way to do this through configuration, or do I just setup a catchall url (dummy send-url in the smsc) for these ? Thanks, Brian
