Hey @miconda,
Yes, calling it in CANCEL block. More complete script would be like this: ``` if (is_method("CANCEL")) { if($hdr(Reason)=="SIP;cause=487;text=ORIGINATOR_CANCEL") t_set_no_e2e_cancel_reason(1); if (t_check_trans()) route(RELAY); exit; } ```
Putting a xlog there shows that the CANCEL matches properly there but no change in reason (cannot be deactivated).
Ta, DanB
