Hi,
Yes I got a different setup with kamailio 4.2.4 where I successfully
register the same UEs. But there we got some kind of issue with the rx
interface and before looking at the code we wanted to update kamailio
version and then see if same rx issue happens. At the moment is not
clear to me the rx issue therefore i couldn't describe it.

Hi Mihail,

you could also see the REGISTER in the PCAP, if you did not configure
your DNS/BIND properly...

Thanks,
Carsten

P.S.: I regularly test Zoiper with our own setup, it works... and it
even should work with the 4.4 version, you're running.

Hi,

the Zone-File is the interesting part, not the Bind-Config.

Did you configure the outbound Proxy on Zoiper properly?

Yes, otherwise the REGISTER from the UE would be missing from the pcap,
right?

You can actually see in the trace, that the Proxy-CSCF is forwarding
the packet to itself (looping) and at some point it drops the request.

I see that as well. I eliminated big part of the log as is the loop
itself. After some time it gets stable. But to estimate the nature of
the loop I get about 1M log lines with debug level 5 for 1 register
procedure triggered from the UE.

I guess i'll check with the trunk code meanwhile.

Thanks,
Carsten

Hi,

DNS error? This is interesting. Well I got a local bind running with a
dnszone provided from ims aio from kamailio.org site. You can have a
look at the bind config which copied adjusting port numbers.
I would say that it does work:

user@host:etc/kamailio$ host hss
hss.open-ims.test has address 192.168.177.100
user@host:/etc/kamailio$ host icscf
icscf.open-ims.test has address 192.168.177.100
user@host:/etc/kamailio$ host pcscf
pcscf.open-ims.test has address 192.168.177.100
user@host:/etc/kamailio$ host scscf
scscf.open-ims.test has address 192.168.177.100

Hi,

looks to me, like a typical DNS error. How did you configure DNS?
You have BIND up and running and a proper Zone-File? Do the CSCF's
properly query the DNS?

Thanks,
Carsten

Hi Folks,

I have the strangest problem just after installing latest stable
version. I had tried both ways using the repo
(http://deb.kamailio.org/kamailio44) and downloading code with local
compile (https://www.kamailio.org/w/2016/05/kamailio-v4-4-1-released/)

The initial scenario is to get M2M with commercial IP and subsequently
use the Rx interface to do the same. We are blocked because we cannot
even achieve clean register for the UEs.

UE1(galaxy s4 zoiper) -------- Kamailio IMS aio
                               |
UE2(galaxy s4 zoiper) -------- |


What happens is that the first register message triggers some
quasi-endless loop in the PCSCF. Hence it cannot be forwarded to SCSCF,
ICSCF and HSS. But this doesn't always happen and between all the parse
problems there are some register messages which get passed to the scscf
icscf and hss. Somehow the parser feeds itself from the previous parse
run and thus loops quite intensively. The message I get is SIP/2.0 400
CSeq method does not match request method.
I must say that reiterating the registration process sometimes i get the
register and sometimes i don't.

Has anyone encounter similar issue for similar use case and can share
some thoughs about a fix?

I attached relevant log file, pcaps and configuration files. Let me know
if more config files are needed.
