I swear, getting OpenSER to do anything is worse than pulling teeth. The avpops module documentation at: http://www.openser.org/docs/modules/1.0.x/avpops.html#AEN165 has the following example under the db_scheme command: ... modparam("avpops","db_scheme", "scheme1:table=subscriber;uuid_column=uuid;value_column=first_name") ... which causes the following error to be reported in syslog.conf: Nov 27 14:24:52 ser1 openser: ERROR:avpops:parse_avp_sb_scheme: unknown attribute <uuid_column> Nov 27 14:24:52 ser1 openser: ERROR:avpops:avp_add_db_scheme: falied to parse scheme Nov 27 14:24:52 ser1 openser: parse error (102,3-4): Can't set module parameter Why? The example at the 'alleged' tutorial at: http://www.voice-system.ro/docs/avpops/ which is just the docs at openser.org cut and pasted mostly has this example: ... modparam("avpops","db_scheme", "scheme1:uuid_col=uid;value_col=job;value_type=string;table=emp") ... which does not generate any errors in syslog. HOWEVER, when avp_db_load() is called, the following is logged to syslog.conf: Nov 27 14:21:42 ser1 openser[2424]: ERROR:avpops_init: "AVP_DB" present but "AVP_TABLE" found empty Nov 27 14:21:42 ser1 openser[2424]: init_mod(): Error while initializing module avpops Why??? The docs say I can use dbscheme to use a non standard AVP table, which is what I am trying to do, namely the subscriber table. If I can use dbscheme to define the columns from another table, why is OpenSER complaining that I haven't called modparam("avpops","avp_table","avptable")????? Doug.
