Hi Sylvain,

I guess you'd need:

• Add a vty option for it
• Add a 'subscr_get_key_seq' helper that either returns the real one

or force 7 if the privacy option is set

• Replace direct subscr->key_seq access by this helper in each of the

3 possible initial messages : gsm48_mm_tx_loc_upd_req, gsm48_mm_tx_cm_serv_req, gsm48_rr_dl_est (in the paging response creation)

wow, thank you so much for directing me.

I made the attached patch. For USSD it is really working. I didn't test more. So if you would be so kind, could you check if every event is covered now (especially things like silent SMS; I don't know how to test that)?

And if so, would you commit the patch in the git?

Cheers and thanks
