I meant that before 4.4.4, I was building from the 4.4 branch will all commits in that branch up until 81df84b . git diff 81df84b 4.4 should show the difference, I just can't figure out what part isn't working.


I am not using t_suspend()/t_continue() or other async processing functions

and I do call route[NATMANAGE] after route[RELAY] from branch_route[MANAGE_BRANCH].

Quoting Daniel-Constantin Mierla <miconda@gmail.com>:

The commit 81df84b is related to tls, so there should be no relation
with nat functions.

Are you using t_suspend()/t_continue() or other async processing functions?

Anyhow, whatever changes you want to be specific for each outgoing
request must be done in a branch_route. request_route changes are
visible to all changes and if you do something again in branch_route or
failure_route, then you will see duplicated operations.

Cheers,
Daniel

Prior to the upgrade to Kamailio 4.4.4, I was using 4.4.3 with updates
through 81df84b from the 4.4 branch and the following fix_nated_sdp
call worked through the initial INVITE and when a voicemail branch was
appended from the failure_route.

route[NATMANAGE] {
...

# RTPEngine is not needed but if STUN addresses are being used on our
# internal network, rewrite the addresses to the internal source address
if(!isbflagset(FLB_RTPENGINE) && has_body("application/sdp")) {
        if(dst_ip==10.1.1.2 &&
compare_pure_ips($sel(contact.uri.host), "<EXTERNAL_IP>")) {
                fix_nated_sdp("10");
        }
}

...
}

Since the upgrade to 4.4.4, when the original INVITE fails over to
voicemail (branch appended), fix_nated_sdp creates the SDP below,
doubling the replaced IP addresses.  Asterisk replies with 488, as the
media address is completely invalid.  I need something like the above
(which worked for the request and the reply) but can't figure out what
the problem is.
