I've done like Rafael told in the e-mail shown bellow for 1.1.x version,

although I was expecting to see in acc table to be written A B and C contacts of forwarded calls (when A calls B and B forwards to C), but there is never written B contact, the one who should be billed for that call... the entries in my acc table for forwarded calls are like this:

| sip_from | sip_to | i_uri | o_uri | from_uri | to_uri | src_leg | dst_leg | |---------------------------------------------------------------------------| | A | C | C | C | A | C | A | C |

As seen, my acc table doesn't show B contact!! How should I edit my openser.cfg file so that B contact be shown in acc table for forwarded calls?

Thanks, Ricardo.

hi ricardo, for 1.1.x version, try this: modparam("acc", "multi_leg_enabled", 1) modparam("acc", "src_leg_avp_id", 110) modparam("acc", "dst_leg_avp_id", 111) ... route {

   ## populate the avps (for Multi call leg accounting):
   if (!method=="REGISTER" && !method=="NOTIFY") {
           avp_write("$from/username", "$avp(i:110)");
           avp_write("$ruri/username", "$avp(i:111)");
     };

.....

for 1.2 or cvs : # for mysql-based accouting, use the names of the columns modparam("acc", "multi_leg_info", "leg_src=$avp(i:110);leg_dst=$avp(i:111)")

Do not forget to add src_leg and dst_leg columns in acc table (leg_src, leg_dst for 1.2)

I want to use Multi Call-Legs accounting to properly account forwarded calls made "in the phones". For example user A calls user B which forwards the call to user C. There is only one SIP call but with 2 legs ( A to B and B to C). Accounting the legs of a call is required for proper billing of the calls.

As can be seen in acc module documentation, I've added the following 3 lines to my openser.cfg script:

modparam("acc", "multi_leg_enabled", 1) modparam("acc", "src_leg_avp_id", 110) modparam("acc", "dst_leg_avp_id", 110)

Although, after testing some forwarded calls, nothing has been written to src_leg or dst_leg columns of acc table!! What have I done wrong? How may I implement this feature correctly?

Regards, Ricardo.
