Hi, I use openser 1.0.1 and tried CVS version with the same config. Something is wrong with AVP's or I don't know something ? Here are relevant config lines: modparam("tm", "fr_inv_timer_avp", "inv_timeout") modparam("auth", "rpid_avp", "rpid") xlog("L_ALERT", "rpid_avp = $avp(rpid)\n"); 0(0) xl_parse_vname: error - avp alias [rpid] not found! 0(0) XLOG:xdbg_fixup: ERROR: wrong format[rpid_avp = $avp(rpid) avp_write("i:45", "inv_timeout"); 0(0) ERROR:avpops:fixup_write_avp: bad attribute name in param 2 <inv_timeout> Something is changed or is it a bug ? I should use new exec_dset features (additional parameters) Thanks, imedve
