Ok so
It now includes the record-route but its still not modifying the
contact header and the problem persists.
¿Any suggestions as to how to do that?
for updating the contact header you have to use nathelper module with
fix_natted_contact(). Be sure you set the tcp connection lifetime
reasonably high to be safe during a call, avoiding a need to reconnect
behind nat, which is not possible:
http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.1.x#tcp_connection_lifetime
I recommend you start from default config file for 3.1, strip the part
with user auth, location, rtp proxy ... and plug in the dispatcher
stuff. You have there proper record routing and nat traversal handling.
A more recent dispatcher config is available at:
http://kamailio.org/docs/modules/devel/modules_k/dispatcher.html#id2522847
It shows serial forking.

Thanks Andrew
Ill deal with the ping config once I resolve the route problem.
So now this is my config:
route{
if (method != "REGISTER")
loose_route();
if (is_method("INVITE"))
record_route();
ds_select_dst("2", "4");
t_relay();
}
Now I can see in the sip headers that it is in fact adding the
record-route properly with the correct ip address of the loadbalancer
and the transport=tcp tag but the problem for incoming calls still
presents itself. The transcoder is still trying to reach the softphone
directly skipping the loadbalancer. Any ideas why would this still
happen? Or did I just screw up the config and oversimplified it?
Thanks again
David

Hi andrew. Thanks for your help. What module or config should I use to
make sure the connection goes back through the loadbalancer?
That's simply the task for record-route like:
if (is_method("INVITE"))
record_route();
But you also need the loose_route for routing new in-dialog requests.
For the failover I didnt specify anything ping related. Im using the
dispatcher module. Can I specify the ping config in that module or
should I use another module for that?
yes, it's in the documentation of dispatcher module:
http://kamailio.org/docs/modules/3.1.x/modules_k/dispatcher.html#id2806108
route{
ds_select_dst("2", "4");
t_relay();
}
well, with such config the chances are that the subsequent BYE may arrive at
the different server than the INVITE, so again you need the loose_route
section for this. You should get familiar with the default config file to
get a feeling of things.
Regards,
Andrew
