Hi I am using kamailio 4.4.2 for load-balancing modparam("dispatcher", "dst_avp", "$avp(dsdst)") $avp(dsdst) getting proper dispathcer value. But this value is null in request_route under iif (is_method("CANCEL")){ } How to get the correct dispatcher value for a particular call -- Thanks and regards Vinod.M.N
