Is it not better to use SEMS as SBC in the front of your network? And all P/S/I/CSCF have the private IP address. Thanks --Mojtaba Esfandiari.S
Hi,
There is a common scenario, where Kamailio needs to be in front of e.g SEMS: PCRF Integration for QoS. You need to access the IP of the sender and the SDP. You would have to integrate that into SEMS, but if you do, you can actually drop Kamailio as a Proxy-CSCf completely...
Thanks, Carsten

Hi, You mean that we should use either SBC or Proxy-CSCF (don't both of them) as entry point of IMS network? Is it right? Thank. Mojtaba Esfandiari.S

Hi,
you can for example buy a Proxy-CSCF from Oracle (the former AcmePacket NET-NET SBC's), which provides such functionality.
I'm working on a new Version of the config, which supports some more options here: 1) Use topos, if e.g. no transcoding is needed 2) Use SEMS or Asterisk like before (with some cleanups/optimizations)
When I talk with customers about commercial deployments, they often refer to Kamailio as a SBC (and since there is no real definition for a SBC, that's probably valid); since it does most of the things, a SBC would do (topology hiding, DOS-Attack detection, Limiting, Header-Manilpulation, Validating of the messages, ...). For me one of the top-reasons for using either SEMS, Frafos ABC-SBC or Asterisk is Transcoding & Topology hiding, as almost everything else can be done on Kamailio too.
Thanks, Carsten

Hi Thank you for your explanation. What is your suggestions about the setup IMS Core Network for area? I mean which of the senario is better? 1) All nodes (P/I/S-CSCF and HSS) have public IP Address in IMS Core Network, While the subscriber just could see PCSCF. In this way we may use some modules to hide topology, e.g TOPOS module. 2) We have one Public IP Address and one Private IP Address for PCSCF, While other nodes (I/S-CSCF and HSS) have Private IP Address. In this way we use Nat modules (or RTP Proxy) for relay RTP. One of major functionality of nat module is relaying RTP between Public IP address and Private IP Address in PCSCF node. Thanks.
