[Users] radius - multi leg accounting

[Bogdan-Andrei Iancu]

Hi Rosario,

with RADIUS, you will get one start (for INVITE) - disregarding the 
number of legs-, a second start record (for ACK) if report-ack is 
enabled and a stop for BYE.

focusing on the start record for INVITE - this record will contain a 
pair of Sip-Leg-Source and Sip-Leg-Destination RADIUS AVPS for each leg. 
So, if you have 3 legs, will get 3 x (Sip-Leg-Source + Sip-Leg-Destination).

from script, for each leg, you need to write into avps the values for 
src and dst:

    ......
    # leg 1
    avp_write("src_leg1", "$avp(i:110)");
     avp_write("dst_leg1", "$avp(i:111)");
     .....
    # leg 2
    avp_write("src_leg2", "$avp(i:110)");
     avp_write("dst_leg2", "$avp(i:111)");
     .....

regards,
bogdan
