[Users] Multi Call Legs Accounting

Hi,

Did anyone successfully setup call accounting for call forward? I have been searching for a working example for few days on google, I still couldn't find any working example.

The config I have at the moment is

modparam("acc", "multi_leg_enabled", 1) modparam("acc", "src_leg_avp_id", 110) modparam("acc", "dst_leg_avp_id", 111)

In the main route, if (!method=="REGISTER" && !method=="NOTIFY") { avp_write("$from/username", "$avp(i:110)"); avp_write("$ruri/username", "$avp(i:111)"); };

Let say A call B and B forward call to C, the record in the acc table is all A to C without B in any one of the record for billing purpose. The Call forward was set on the UA.

Can anyone give me a hand on this please?
