Hi,

IMS uses the SGi interface via the Gm interface (P-CSCF), which is available at Kamailio P-CSCF.

You will have to configure P-CSCF discovery at the EPC (or the address of the P-CSCF directly at the UE).

Sorry, I personally do not know a way to build a PCRF by Kamailio, but a PCRF is a diameter server, e.g. like a HSS.

Kamailio has a lightweight diameter server module, maybe it can be used: https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_server.html

Just my two cent

All the best

Christoph

Hi,

I am trying to connect EPC with IMS.

EPC is separate installation of comac-in-a-box . IMS is kamailio based. Do i have SGi interface configurations in kamailio so that i can establish communication between EPC and IMS.

One more clarification. I have seen PCRF communication can be done using CDP .Is there any way to build PCRF as part of kamailio.

Kindly help .. 

Thanks,

Pavithra
