Dear All
I have tried a lot and looks getting Kamailio IMS setup is very difficult
and no proper documentation available. Though I have setup all CSCFs and
FHoSS , still REGISTRATION fails with 483 response.

I have setup DNS properly as shown below.

When I send a REGISTER message from a sip client, I get 483 Too Many Hops.


I am totally clueless whats going wrong.

Can somebody guide me , where is the fault.



On thing I do not understand is dispatcher.list stuff.

So I have kept empty disptacher.list file for PCSCF and SCSCF.
Can that be an issue.


The REGISTER and 483 response looks as below.

Dear Carsten
group1-imslab11.in points to same machine where all CSCFs are running.
In this case it is 192.168.1.100.
From machine, where I run sip client, I pinged to group1-imslab11.in

Hi Kamal,

where did you retrieve the config? At some point i made the mistake of
putting "dns_try_naptr=yes" (which should be "no") in the config,
which could lead to the issue your seeing... can you check this?

Kind regards,
Carsten

P.S.: The dispatcher.list file is used as a "Whitelisting" for the
DDOS-Check on the Proxy-CSCF, so the IMS-Core components are not
beeing blocked by the pike-check. On the Serving-CSCF it contains the
PSTN-Gateways.

Dear Carsten
I tried suggested command. Output as below.
192:~$ host -t SRV _sip._udp.group1-imslab11.in
_sip._udp.group1-imslab11.in has SRV record 0 0 5060
icscf.group1-imslab11.in.
192:~$
Many thanks

Hi,

Post by Kamal Palei
Dear Carsten
group1-imslab11.in points to same machine where all CSCFs are running.
In this case it is 192.168.1.100.
From machine, where I run sip client, I pinged to group1-imslab11.in
192:~$ ping group1-imslab11.in
PING group1-imslab11.in (127.0.0.1) 56(84) bytes of data.

64 bytes from localhost (127.0.0.1): icmp_req=2 ttl=64 time=0.033 ms
What is painful is, I am not getting the way out..., how do I debug or
troubleshoot?
Please guide me where I need to concentrate...,
I doubt either DNS or dispatcher.list file....
Many thanks

Hi Carsten,
There is not entry for dns_try_naptr in any of my config file.

Regarding dispatch list, I do not have PSTN gateways.., what shall I put in
dispatcher.list file for SCSCF.


I tried to comment loading of dispatcher module, but endup getting error in
kamailio.cfg (looks some functions are referred from dispatcher module in
kamailio.cfg).


Totally clueless.., Not sure how to proceed.

many thanks
kamal

Hi Kamal,
where did you retrieve the config? At some point i made the mistake of
putting "dns_try_naptr=yes" (which should be "no") in the config,
which could lead to the issue your seeing... can you check this?
Kind regards,

P.S.: The dispatcher.list file is used as a "Whitelisting" for the
DDOS-Check on the Proxy-CSCF, so the IMS-Core components are not
beeing blocked by the pike-check. On the Serving-CSCF it contains the
