... via the GSM SMS dissector that is (which should pass messages with UDHI onto the GSM SMS UD dissector). Might be nice in future to be able to pass messages without a UDH to the GSM SMS UD, but I'm not sure how best to do this. You'd want to be able to pass to the dissector, along with the tvb:

- Whether or not there is a UDH present
- The GSM DCS value (or at least whether the body is 7bit, 8bit or UCS2)
- Whether 7bit infomation is packet into bytes (as in the GSM SMS TPDU) or with every 8th bit zero (as in an SMPP PDU).

Any thoughts how this information could be passed?


Cheers,

Chris
