Hi all, I have successfully setup a Kamailio IMS environment using just a single machine running three kamailio instances. I am using kamailio 4.2.4 compiling it myself. I followed this guide: http://nil.uniza.sk/instant-messaging/simple/configuring-im-and-presence-ka… to setup a presence AS using the scscf instance. I used kamdbctl script to create the presence tables with one inconsistence with the guide. I had to create a db in which I created a couple of columns (table_name, table_version) to satisfy the kamdbctl script as it was failing when running "kamdbctl presence". At the moment the problem is that my kamailio instance is failing with the following error: scscf/scscf[5256]: ERROR: <core> [db.c:422]: db_table_version(): invalid type (3) or nul (0) version columns for presentity ... and then some time later: scscf/scscf[5256]: ERROR: <core> [db.c:440]: db_check_table_version(): querying version for table presentity scscf/scscf[5256]: ERROR: presence [presence.c:322]: mod_init(): error during table version check scscf/scscf[5256]: ERROR: <core> [sr_module.c:968]: init_mod(): Error while initializing module presence (/home/ng40/kamailio-4.2.4/modules/presence/presence.so) scscf/scscf[5256]: DEBUG: cdp_avp [mod.c:224]: cdp_avp_destroy(): Destroying module cdp_avp I suspect that the problem relays on creating manually the db where I inserted the two columns mentioned above (table_name, table_version) so that I could execute "kamdbctl presence". Could someone assist me into solving this issue? br, md.
