[SR-Users] Unable to get avp value in response

I am trying to set a value to an avp on the request route, but when I try to read the avp on the reply route I always get nil. On the route I have this: KSR.xlog.xinfo("invite_request: ********** Setting avp test\n") KSR.pv.seti("$avp(test)", 1) KSR.xlog.xinfo("invite_request: **** " .. tostring(KSR.pv.get("$avp(test)")).."\n") On the reply route I have this: KSR.xlog.xinfo("response_invite: **** " .. tostring(KSR.pv.get("$avp(test)")).."\n") In the logs I see on the INVITE: Aug 8 13:49:15 test /usr/sbin/kamailio[1927947]: INFO: [a0748d39-3f17-4080-b5ed-0a6b7019cb95 INVITE 1]invite_request: ********** Setting avp test Aug 8 13:49:15 test /usr/sbin/kamailio[1927947]: INFO: [a0748d39-3f17-4080-b5ed-0a6b7019cb95 INVITE 1]invite_request: **** 1 ... ...
