[Users] radius - multi leg accounting

Hi list I need to implement multileg radius accounting on openser 1.1.x cfg. I have configured radius to handle Sip-Leg-Source and Sip-Leg-Destination. The problem is to configure openser.cfg propely. In the beginning i have: modparam("acc", "multi_leg_enabled", 1) modparam("acc", "src_leg_avp_id", 110) modparam("acc", "dst_leg_avp_id", 111) then in the route that handle the invite I load the avp by radius: avp_load_radius("callee"); But then I miss the point to have two accounting start and two accounting stop, one for each leg. Then...if it is not possible to have two accounting records, I would liek to know how to store all the information of the two legs insede one start and one stop. something like this one? avp_write("$from/username", "$avp(i:110)"); avp_pushto("$ru","$avp(s:callee_callfwd)"); avp_write("$ruri/username", "$avp(i:111)"); Hope some one can drive me to understand better this situation.
