2833 is the default. INBAND is not a function of the sip module it's implemented on top of the abstraction layer.
Are you doing trans coding or different ptimes between the 2 legs? you might want to turn up the debug log "press f8" and you will pretty verbose logging of the 2833. also consider taking a pcap of the network traffic. What is the provider? 2833 is notoriously done wrong to the point that doing it exactly right can put you at a disadvantage.
