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.
Julian.

Hello,
for reference, in case kamailio is running behind nat, like on AWS, one should just use advertise directive for listen parameter, like:>
listen=proto:privateip:port advertise publicip:port>
See:
http://www.kamailio.org/wiki/cookbooks/4.0.x/core#listen
It simplifies the config by not needing to use alias parameter, advertised_address/set_addvertised_address() and record_route_preset().>

It's difficult and time consuming to debug issues without seeing the config file and without seeing the packet traces (ngrep -W byline -d any -t -q -p "" port 5060).
Anyway, as an admin you should understand how Kamailio works. Thus it would be a good exercise to find the problem yourself. In severl places in your config you have routing decisions (if ... {}). Identify these places, and put meaningful logging (xlog("...") ) before and after the if statement.
Then make a call and watch the logfile. This will give you an understanding how Kamailio works.
regards Klaus

Thank you Klaus i am trying to do that myself if you see on my config on the body of the message i log everything i solve the issue by providing a specific route and eliminating 0 in from of the prefix, it is ok but kamailio still not recognizes itself on aws setup even when i had advertise both ips and i had alias for both ips, if i dont define enything it will loop over until exhaustion, for now i reply with 488 wich tell me something is bad but i thought that kamailio will know when a message is send from itself to itself.
i appreciate your recommendations, unfortunately since i solved that way i have no more traces i will take the routing i added then i will sent some packed traces.
thank you.

It's difficult and time consuming to debug issues without seeing the config file and without seeing the packet traces (ngrep -W byline -d any -t -q -p "" port 5060).
Anyway, as an admin you should understand how Kamailio works. Thus it would be a good exercise to find the problem yourself. In severl places in your config you have routing decisions (if ... {}). Identify these places, and put meaningful logging (xlog("...") ) before and after the if statement.
Then make a call and watch the logfile. This will give you an understanding how Kamailio works.

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.

Hello,
for reference, in case kamailio is running behind nat, like on AWS, one should just use advertise directive for listen parameter, like:>
listen=proto:privateip:port advertise publicip:port>
See:
http://www.kamailio.org/wiki/**cookbooks/4.0.x/core#listenhttp://www.kamailio.org/wiki/cookbooks/4.0.x/core#listen
It simplifies the config by not needing to use alias parameter, advertised_address/set_**addvertised_address() and record_route_preset().>
Cheers, Daniel

for now i reply with 488 wich tell me something is bad but i thought that kamailio will know when a message is send from itself to itself.
Sending a message to itself is a legal use case (it is called "spiraling"), thus there is no such automatic detection in Kamailio. Spiraling is OK, as long as the spiral stops somewhere.
