Hi!

I'm using openser CVS and try to deliver the rpid using auth_radius. But the rpid never appears in the AVPs. Also other AVP-SIP attributes (e.g. SIP-AVP = #101:TEST) do not appear in the AVP.

Filling AVPs in the .cfg using avp_write("$ruri/username","$ruser"); works fine and are printed with avp_print.

Any ideas how I can track down this problem?

thanks klaus

The radius server responds with a SIP-AVP (225) attribute (verfied with tcpdump): rpid:sip:+4359966366102@1013cbc.com

my cfg snippet (full config attached): if (!radius_proxy_authorize("")) { xlog("L_WARN","wrong or no credentials - challenging client ..."); proxy_challenge("", "0"); exit; }; xlog("L_WARN","start avp_print()-"); avp_print(); xlog("L_WARN","stop avp_print()--");

the debug log: 8(5807) checking REGISTER authentication ... 8(5807) check_nonce(): comparing [42e78dca8153d605c63042be302f64af00e1abfc] and [42e78dca8153d605c63042be302f64af00e1abfc] 8(5807) DEBUG:auth_radius:radius_authorize_sterman: Success 8(5807) xl_printf: final buffer length 37 8(5807) start avp_print() - 8(5807) xl_printf: final buffer length 37 8(5807) stop avp_print() -- 8(5807) xl_printf: final buffer length 58
