Hi Users;

hope u all are fine. i am new in openser so i am
facing problem .right now i have to implement trusted
ip example
like:(http://www.voice-system.ro/docs/avpops/ar01s08.html#ex_trusting)
i have set the tables of mysql as describe in the
example and all put the routing scripts .When i run
openser it does not show any avp value printed in my
(/var/log/messages).
plz help whether my code is wrong or something else i
have to be done before that.Any help for DEBUGGING
enable .
Thanks and Regards 
Tanzeel
