Onderwerp: Re: [OpenSIPS-Users] ACK Routing Issue
Thanks Diptesh
I'm using topology hiding, so now I have this:
if (has_totag()) {
xlog("CUSTOM_LOG: in-dialog $rm has message flags: $mf and
branch flags: $bf");
#Set correct SIP User-Agent Header
if (remove_hf("User-Agent")) {
xlog("CUSTOM_LOG: Setting SIP User-Agent on In-Dialog Request");
insert_hf("User-Agent: OpenSIPS\r\n");
}
if (!topology_hiding_match() ) {
xlog("CUSTOM_LOG: cannot match request to a dialog \n");
send_reply(404,"Not found");
}
# handle hop-by-hop ACK (no routing required)
if ( is_method("ACK") && t_check_trans() ) {
xlog("CUSTOM_LOG: ACK detected with valid transaction -
t_relay");
t_relay();
exit;
}
I don't see a 404 going out so I think topology_hiding_match is working.
But it tries to send the ACK to itself on it's private interface (I have
mhomed=1).
ACK
sip:[email protected]<mailto:sip%3A%[email protected]>;did=e07.595f3776
SIP/2.0
Via: SIP/2.0/UDP PUB.LIC.IP.ADDR:5060;branch=z9hG4bKc219.d1f5b08.2
From: <sip:[email protected];user=phone>;tag=gK0c801c8d
To:
<sip:[email protected]<mailto:sip%3A%[email protected]>>;tag=3800350621-1224267434
Call-ID:
[email protected]<mailto:[email protected]>
CSeq: 202841 ACK
Max-Forwards: 69
Content-Length: 0
Best regards
Mark.

Hello Mark,
Are you using Topology Hiding or Loose Routing?
If you are using Topology Hiding then you need to match the topology using
topology_hiding_match() first.
It is great if you can share SIP packets.
Thanks & Regards

Hi everyone
I've upgraded an OpenSIPS box to 3.1 and am now seeing an issue with ACK's
trying to route to an incorrect IP - in this case our own advertised IP.
I think I'm right in saying that PRACK's & ACK's are treated equally and should
route in the same manner? However, PRACK's are routing correctly.
I have this:
if (has_totag()) {
---
# handle hop-by-hop ACK (no routing required)
#if ( is_method("ACK") && t_check_trans() ) {
if (is_method("ACK")) {
t_relay();
exit;
}
---
Thanks for any ideas!
Mark.
