Hello,
I have Kamailio 3.1.0 behind a NAT. We need the Firewall for sip-security reasons. Currently I'm using record_route_preset("advertised_Address") for keeping the advertised address in the record-route header. This works for fine when I have all clients running on UDP protocol.
I currently have some TLS clients added to our network, Kamailio does not insert the second record-route header with the advertised-IP whenever there is a call between a UDP and a TLS Client. Instead it inserts the internal/Local IP of the server.
I had also noticed the record_route_preset() function does not include the transport parameter ("transport=UDP" or "transport=TLS").
I was looking through the source code of Kamailio and found record_route_advertised_address() in record.c . I would like to know how to use this function with the Kamailio config.
Regards Gnani
The fact that there is a function in the source code does not mean you can use it in the route script; functions have to be properly defined and exposed/exported to make that happen. Indeed, there are far more functions in the C source than in the modules' exported parameters list.
Check the 'rr' module reference for more info.

Take a look at set_advertised_address: http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.1.x#set_advertised... Set it and then record_route() will properly fill the Record-Route header.

Hi, I do not think that record_route() uses the advertised_address variables. We have been using the advertised_address / advertised_port variables in the config file and although they are used in the Via headers, they are not substituted into the Record Route lines.
record_route_advertised_address() was added about 2 weeks ago for exactly this reason - using an advertised address in record routes when the transport changes. It automatically inserts double (rr2=on) routes in these cases and extra custom parameters can be added later.
However, we only needed the C API, so it isn't exported as a config file function yet. This won't be difficult.
Regards, Hugh

Hello,
maybe the option for now is to set the parameters for record_route_preset() to advertised_address/port:
http://kamailio.org/docs/modules/stable/modules_k/rr.html#id2542169
I have some deployments (like on EC2) where I use advertise_address for have the proper Via and record_route_preset() for record route headers.
For simplicity, it would be good to have the function in config to take advertised address value for building the rr header.
Cheers, Daniel

Hi, I've implemented the config file function for record_route_advertised_address and it should appear in git head later today. Just doing the documentation and some testing...

Hi,
The record_route_advertised_address() config file function is now in git master.

from the readme I see that it takes the address from the function parameter, not from advertised_address global parameter, which is getting close to what record_route_preset() does, just that record_route_advertised_address() can do double rr with the address parameter based on auto-detection of transport change.
Probably would be useful to have the option of no parameter for this new function, in which case the global parameter advertised_adress/advertised_port will be used for building rr.
