Hi Mojtaba, Thanks for your answer. Actually I know what you mean. In my question I skipped all the steps of signaling. Since my question is to be able to use Kamailio as a P-CSCF node.
So I guess we can install I-CSCF, S-CFCF and HSS in seperate machines (VMs).
I am already aware of the signaling of IMS entities. But I wonder how can I use kamailio as a P-CSCF node. and which modules should I install? I want to install kamailio as a PCSCF on ubuntu18. When I look at some IMS kamailio integration I see all IMS modules are installed. BTW I also tried to install IMS modules on my ubuntu18 but I got some errors during loading some modules as follow:
ERROR: <core> [sr_module.c:582]: load_module(): could not open module </usr/local/kamailio-4.4/lib64/kamailio/modules/cdp.so>: /usr/local/kamailio-4.4/lib64/kamailio/modules/cdp.so: undefined symbol: get_str_hash
ws_frame.c:32:10: fatal error: unistr.h: No such file or directory #include <unistr.h> ^~~~~~~~~~ compilation terminated. ../../Makefile.rules:97: recipe for target 'ws_frame.o' failed
Thanks & Regards,

Hello Serkan, In IMS concept, In while Registration flow, the scscf is selected by I-CSCF node. Then, When the UE is registered in IMS (SCSCF node), The SCSCF node would be appear as Service_Record header in SIP body. The UE is aware about the it's SIP serving in IMS, and when it originate new call, the PCSCF forward it's call to desired node. For more information refer to 3gpp documents. With Regards.Mojtaba

Hi all, I want to use Kamailio as a P-CSCF on ubuntu 18. Kamailio will be p-cscf and will communicate scscf in another open-ims
box.
How can I implement this feature. I have already looked following link. However it did not help me since I could not see any example pcscf configuration files after installation
