Re: [Users] RE: [Serusers] Re: [Serdev] Inaccurate Radius Accounting

Hello, Attached is a patch that implements "swap_direction" parameter of acc module. If you turn the parameter on in the configuration file: modparam("acc", "swap_direction", 1) then the acc module will swap Calling-Station-ID and Called-Station-ID values when necessary (in this case BYE comming from the callee).

Put the patch in top level source directory (ser-0.9.x) and type: patch -p0 < swap.patch The patch should work with any 0.9.x release. Note that Alan DeKok is wrong in thinking that this is a bug in SER. This particular problem is a result of incomplete specification of RADIUS use with SIP. I will commit the patch in CVS so it will be included in future SER releases. Jan.
