[Kamailio-Users] Using pua_bla for BLF

Hello I am trying to make some phones work with BLF using Kamailio and I found an older messge ( http://lists.kamailio.net/pipermail/users/2007-October/013700.html) saying that I could do this using BLA. I have a Thomson ST2030 as the message says, but it doesn't work with presence and pua_bla. I get the error: ERROR:presence:handle_subscribe: Missing or unsupported event header field value ERROR:presence:handle_subscribe: event= dialog I undestood from that message that the event is supposed to be 'dialog', so what's the problem then? Thanks a lot Catalina
