Re: [Users] Cisco-like Radius accounting

Hi, I have a radius accounting configuration I would like to share, if someone needs. Please can I get your feedback guys if this can be done in a better way. Just share your thoughts if you have done something similar. I need to account to my RADIUS the source IP (of the calling UA), the destination IP (called UA/gw) and the type of the leg - originating or terminating depending on whether the call is from the UA or to the UA. To do this I decided to use the cisco vendor-specific radius AVPs which have similar fields but for h323 calls. In my dictionary file of radiusclient-ng i added this according to the cisco specification: VENDOR Cisco 9 ATTRIBUTE Cisco-AVPair 1 string Cisco ATTRIBUTE H323-remote-address 23 string Cisco ATTRIBUTE H323-call-origin 26 string Cisco and in my openser.cfg i have: modparam("acc", "radius_extra", "Cisco-AVPair=$avp(s:c_src_ip); H323-remote-address=$avp(s:c_dst_ip); H323-call-origin=$avp(s:c_origin); Cisco-AVPair=$avp(s:c_call_id)") Now in my config i fill in the values of the c_src_ip, c_dst_ip, c_origin, and c_call_id avps according to the direction of the call. Here is how i do it for the originating leg, terminating is similar: route[14] { #ACCOUNT ORIGINATING if (is_direction("downstream")) { avp_printf("$avp(s:c_src_ip)", "call-origin-endpt=$si"); avp_printf("$avp(s:c_dst_ip)", "$ru"); avp_subst("$avp(s:c_dst_ip)", "/sip:.*@(.*)/h323-remote-address=\1/g"); avp_subst("$avp(s:c_dst_ip)", "/(.*):.*/\1/g"); avp_printf("$avp(s:c_origin)", "h323-call-origin=originate"); avp_printf("$avp(s:c_call_id)", "call-id=$ci"); } if (is_direction("upstream")) { avp_printf("$avp(s:c_src_ip)", "$ru"); avp_subst("$avp(s:c_src_ip)", "/sip:.*@(.*)/call-origin-endpt=\1/g"); avp_subst("$avp(s:c_src_ip)", "/(.*):.*/\1/g"); avp_printf("$avp(s:c_dst_ip)", "h323-remote-address=$si"); avp_printf("$avp(s:c_origin)", "h323-call-origin=originate"); avp_printf("$avp(s:c_call_id)", "call-id=$ci"); } setflag(2); } Now as you can see i take one of the IP addresses from the request-uri (and strip it with avp_subst), which I am not sure if always contains IP. Is there a better way - i can call this route after rewritehostport or lookup so the destination IP will hopefully be in the r-uri of the message, but maybe there is a better way of getting it? Any input/ideas will be greatly appreciated. Best, Dimo _______________________________________________ Users mailing list Users(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/users
