This would not work if I dont have access to the proxy that is
advertising a private address in the record-route header, thanks for the
tip though.

You may introduce advertise command in the configuration files when

Like this way :
listen=private ip advertise public ip

Hi All,
I've come accros a scenario where a proxy is sitting on a private
address range and inserts a record-route specifying the the
private address.
This causes issues whereby the BYE to an INVITE attempts to relay
to the
private address defined in record-route.
I was wondering, if we were inject a received and rport parameter
into
the record-route header of the original invite, whould kamailio relay
the response (BYE) to the receive/rport destination instead of the
uri
defined in the record-route header.
As an example, initial invite comes in with a record-route as follows:
Record-Route: <sip:172.17.0.2:5062;lr;ftag=b4551d29>
If we injected received and rport as follows:
Record-Route:
<sip:172.17.0.2:5062;lr;ftag=b4551d29;rport=33429;received=212.172.2.212>
and relayed the message to the B2B.
Then, I assume, when the B2B creates its BYE message, the Route
header
should look like this:
Route:
<sip:172.17.0.2:5062;lr;ftag=b4551d29;rport=33429;received=212.172.2.212>
Once this hits the kamailio instance to relay to the last route
header
as mentioned above, would it set $du to received:rport like it
does with
Via headers?
Thanks
