I think disabling MO in the AT module is possible if you set sim buffering to false and specify the proper CNMI string for your modem that disables MO indications.

The SMSC AT module has no way to "refuse" MOs directly. It will send any MO to your connected smsbox instance. If you have no application driven MOs that you want to receive, then you can drop the MOs to nirvana and ensure that there is no response bounced back to the originator, i.e. via config context group = sms-service keyword = default text = "No action specified" max-messages = 0 You WILL still see the MOs in the bearerbox access-log and the smsbox access-log though. It MAY BE an option to think about a config directive for the SMSC AT module to "turn off" MO interpretation and simply drop anything we get on the modem. @devel: Anyone from the SMSC AT developer folks that wants to pick this up? -- Best Regards, Stipe Tolj ------------------------------------------------------------------- Düsseldorf, NRW, Germany Kannel Foundation tolj.org system architecture http://www.kannel.org/ http://www.tolj.org/ st...@kannel.org s...@tolj.org -------------------------------------------------------------------
