Daniel, Klaus thanks a lot for your responses i do appreciate them, just got me a bit confuse because on the documents as what Daniel suggest to advertise directive for listen parameter, I do if you see my config below that i advertise it and have an alias, kamailio still sends an invite to itself without recognizing that it came from the internal ip.
Is there anything else wrong that i am not putting on my advertise line ? thanks i really apreciate your input.
