[Serusers] ACC and Radius

Hi Guys I read radius howto and download and compile all necessary files and install all of them and then recompiled SER for supporting Radius.Authentication with radius is work great but about accounting nothing happend.(I read the acc and radius howto and know that i should uncomment 2 lines on Makefile of acc module and did it)I tested radius by a H.323 gateway and it worked and loged accounting packets but when i want to log SER it does not work, here is my ser.cfg file that related to accounting: # ACCOUNTING modparam("acc", "radius_config", "/usr/local/etc/radiusclient/radiusclient.conf") modparam("acc", "service_type", 16) modparam("acc", "radius_flag", 2 ) modparam("acc", "radius_missed_flag", 3) if (method=="INVITE") { log(1, "INVITE--ALIREZA\n"); setflag(2); }; if (method=="BYE") { log(1, "BYE--ALIREZA\n"); setflag(2); }; I read acc howto and copy the configuration from that but nothing was changed, after that i changed radius_flag and service_type to defualt values (1,15)but it does not still work.I saw some logs in /var/log/message that said: " ser[5029]: INVITE--ALIREZA " it seems ser log the invite correctly (as i configured) but nothing happens on radius. Any sugesstion appreciated. Alireza
