Thank you for Your response Daniel. I was able to solve the problem doing a step by step inclusion of the #!define WITH_ASTERISK function and restarting kamailio every time. I believe I had a typo or so. I also had not configured the append_fromtag Parameter. I believe I was able to integrate kamailio with Freepbx but now my users register in Freepbx even if they are not created in Kamilio but as long as the user name and password are valid, I change the password location to a different table so Asterisk don't ask twice for authentication.. I sent another post about his. Thanks a lot Carlos.

Maybe you can give the diff against the default config file and we can spot what is the issue. Otherwise, give here the content of the lines pointed by the error messages.
