Hello,

my remark was related to the fact that you may have another record_route*() function executed in the configuration file for the same SIP request.

It may be simpler also from routing/security point of view to use different ports for internal and external communications. E.g., port 5060 for communication with internal and port 5080 for external. The you can do advertising on the listen with external port:

listen=udp:localip:5060
listen=udp:localip:5080 advertise externip:5080

Then you just need to force the socket to be used before sending out to use the right port and record_route() will do the rest.

Cheers,
Daniel

Hi Daniel

I use it once, i have read about double record routing and it seems in kamailio only possible if two ips are configured?:

Im using Kamailio behind NAT with advertised address and proxy to an external provider but i have seen , with Asterisk behind, Record route is wrong to Asterisk so i plan to change in order to do not lose ACks .

Any idea to do it better ?

Hello,

can you check in the config and see if there is any other record_route*() function used?

Cheers,
Daniel

Im fancing some issues due to kamailio behind nat and thought double record route could help me .

But enabling that :

modparam("rr", "enable_double_rr", 1)

And later using

record_route_advertised_address("X.X.X.X:5060");

is giving me this error:

 w_record_route_advertised_address(): Double attempt to record-route

Off course, only a single Record Route is present..

What am i doing wrong?

Using Kamailio 4.3.4
