[Serusers] avp_radius and avpops

Hello List. I have a question regarding the use of avp_radius and avpops. I'm using avp_radius to obtain an AVP value from my database via radius. What i what to do is replace this value for the RURI. Here i have a couple of questions. 1.- The value returned by the avp_radius (the SIP-AVP) where is stored ? It suppose that the SIP-AVP returned by radius has the form of "name:value". That "name" refers to the name of what?. For example i'm returning : "var1:sip:1234567@mydomain.com". What i see in the debug is : avp_load_user: AVP 'var1'='sip:1234567@mydomain.com' has been added This is what i got in my ser.cfg (a snippet). if (method=="INVITE" || method=="CANCEL") { if( !avp_load_radius("caller")) { log (1, "AVP_RADIUS: Fail on avp_radius\n"); }; if( !avp_pushto("$RURI", "s:var1/g")) { log (1, "AVPOPS: Fail on AVPOPS\n"); }; }; Again the debug = 9 . 6(23815) avp_load_user: AVP 'var1'='sip:1234567@mydomain.com' has been added 6(23815) qm_free(0x8123400, 0x8166ccc), called from avp_radius.c: load_avp_user(344) 6(23815) qm_free: freeing frag. 0x8166cb4 alloc'ed from avp_radius.c: load_avp_user(330) 6(23815) DEBUG:avpops:pushto_avp: no avp found 6(23815) AVPOPS: Fail on AVPOPS What i'm doing wrong? Thanks! Regards Ricardo Martinez
