Hi Kamal,
where is group1-imslab11.in pointing to? Especially the SRV-records for that domain?
Thanks, Carsten

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.
