[SR-Users] Kamailio IMS NAT issue: PRACK/ACK RURI changing in P-CSCF

[Carsten Bock]

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
