Hello, To quote the e-mail from Ovidiu some days ago: "Take a look at the new param: https://kamailio.org/docs/modules/5.3.x/modules/dispatcher.html#dispatcher.… Up to version 5.2, regular AVPs were used, but starting with version 5.3 the regular AVPs were replaced by an XAVP." So you need to replace the old parameter with the new one.
