Hey everyone, I attempted at first to post this issue in openser's mailing list but have failed to get a reply and thus I am trying in freeradius's as I hope there are people here with similar experience. OpenSER is a SIP Proxy tool and I integrated it to send accounting records to a freeradius deployed server. To do that I had to patch a source copy of freeradius and provide both the radius server and client the appropriate dictionary files. What I would like is the ability to extend the formal SIP ATTRIBUTES with my own set. And so, I tried adding myself some custom attributes to both dictionary files, the one on the freeradius server and the other on openser's radiusclient-ng server and tried for example this: ATTRIBUTE Sip-Src-IP 900 string ATTRIBUTE Sip-Src-Port 901 string ATTRIBUTE Sip-Hdr-Contact 902 string ATTRIBUTE Sip-Hdr-UA 903 string ATTRIBUTE Sip-Hdr-From 904 string ATTRIBUTE Sip-Hdr-Media 905 string But this fails to work, openser/radiusclient-ng is sending accounting records still but specifically without the above attributes even when they are defined in both server and client's dictionary.sip files. My question is why, and how is it possible to do that? And the second question, is there a more extensive dictionary.sip file? Thanks, Liri.
