Yes but 2 problems with this:
1) listen parameter does not seem to accept an SRV or hostname
listen=udp:MYPRIVATEIP:EXTERNALPORT advertise EXTERNALHOSTNAME
causes the listen line to be ignored
2) My goal is not to do any state replication so I only want the SRV in
record-route not VIA. VIA will still have IP. These are very light configs
(no Dialog or backends etc) If a kamailio goes away, an in-dialog request
should still hit another kamailio and the call will progress as if nothing
happened. (Yes, in-progress Transactions will still fail but that's
acceptable vs cost of TM replication)

Hello,
if you control the freeswitches or change where they send traffic/receive
traffic, then I recommend to use two listen parameters with advertise
address, like:
listen=udp:my.ip.ad.dr:5060 advertise publicsrv:5060
listen=udp:my.ip.ad.dr:5080
and carriers will be linked to my.ip.ad.dr:5060, while for freeswitch you
use udp:my.ip.ad.dr:5080. You can use
force_send_socket()/set_send_socket() or $fs to enforce a specific socket
for sending traffic (e.g., towards freeswitch or carriers).
There will be two record-route headers, but, besides enforcing sockets,
everything else will be done automatically.
Cheers,
Daniel

carrier<---->kamailioes<----->freeswitches
I am sending a record route header with a private SRV in the direction of
freeswitch boxes and removing it when sending packets to carrier. I am
using a different (pubic) SRV in contact header being sent to the carrier.

Hi,
why are you calling record_route_advertised_address(..) on these replies
or in-dialog requests? The record_route functions are usually used on
initial dialog forming requests (INVITE, SUBSCRIBE etc..).
Cheers,
Henning

They occur when calling it on responses to the initial INVITE, for
example 183 and 200 OK.

Hello,
are those messages printed during the processing of the initial INVITE or
when handling requests within dialog (re-INVITE, BYE, ...).

Any ideas? I'm considering using insert_hf() to manually add it and
bypass whatever check is failing. Thoughts?
Thanks
