Dear IMS enthusiasts :-)
Has anyone experience with Kamailio IMS (CSCF) setups, where users with different domain names can be registered at one and the same S-CSCF?
Is this feasible at all?
I mean one IMS for users <user>@ims1.example.com, <user>@ims2.example.com, <user>@ims3.example.com,........ in one and the same S-CSCF, I-CSCF, P-CSCF.
Thanks, Christoph
Hi, Christoph. To serve different domains you need to map fqdn received from UE/multiple domains - to the naptr of your I-CSCSF..
To achieve that in my IMS setup I created 3gppnetwork.org.zone which resolve all dns naptr queries like ims.mnc0xx.mccyyy.3gppnetwork.org - to naptr record of local I-CSCF - like below: *.3gppnetwork.org. 1D IN NAPTR 30 100 "s" "SIP+D2U" "" _sip._udp.ims.mnc001.mcc001.3gppnetwork.org. -- obelousov.tel
