Did a small check and the CSeq is incremented, the config snippet:
``` request_route {
if(is_method("OPTIONS")) { sl_send_reply("200", "ok"); $uac_req(method)="INFO"; $uac_req(ruri)="sip:test@" + $Ri; $uac_req(furi)="sip:test@" + $Ri; $uac_req(turi)="sip:test@" + $Ri; $uac_req(auser)="test"; $uac_req(apasswd)="test123"; uac_req_send(); exit; } if(is_method("INFO")) { if (!pv_auth_check("$fd", "test123", "0", "1")) { auth_challenge("$fd", "0"); exit; } } sl_send_reply("200", "ok"); } ```
And the sip trace for info request:

If you want to do something else, then likely you want a new feature. Closing this one.
