Hello everybody, I am trying an INVITE with a SBCs but fails, finding out it seems the Session-Expires doesn't include the param refresher= and according to this closed issue is already included https://github.com/kamailio/kamailio/issues/288 but I cannot achive this, I read the sst module documentation but I don't see anything related this parameter. So, in summary the SBC expects the following: Session-Expires: 1800; refresher=uac; Min-SE: 600 I set only: modparam("sst", "enable_stats", 1); modparam("dialog", "dlg_flag", 5) modparam("sst", "sst_flag", 6); modparam("sst", "min_se". 1800); Now on the invite I the setflag(); 5 and 6 so I see now the header Session-Expires: 1800 but not the refresher=uac; and also I don't see how to set the Min-SE:600 Could you please point me to the right direction? Any hint would be very helpful. -- Jose Figueroa Software Engineer
