[OpenSER-Users] Do AVP's really exist in entire transaction?

Hi, in order to not apply RtpPrxy if the called is an Asterisk (that supports "comedia") I load "usr_preferences" table looking for "pbx_comedia" attribute for called domain. If it's, then it's created a avp: avp(s:pbx_comedia)="yes". But when I try to test this AVP in the "on_reply_route" (to not apply RtpProxy) this AVP has null value. In fact it's easy to see: ------------------------------------------------------ route[3] { ; INVITE route $avp(s:test)="hello"; ... route(1); } onreply_route[1] { xlog("L_INFO","----- avp(s:test) = $avp(s:test) ------\n"); } ------------------------------------------------------ The xlog of onreply_route shows: ----- avp(s_test) = null ----- is it normal? aren't AVP's transaction aware?
