[SR-Users] IMS - change the transport layer protocol for Diameter based interfaces (especially Rx)

Hi Björn,

this misunderstanding was my fault. We have a drop-in replacement for the
Diameter-Stack developed in house (based on FreeDiameter), which we
originally wanted to publish in the Kamailio project. This is what I was
referring to in that talk.

However, after discovering several "commercial" IMS solutions based on
Kamailio (without mentioning Kamailio), some bad client discussions ("Why
should we pay for something, if we get the same features through the
open-source version later anyway?") and some people calling us twice a day,
claiming they would need instant support for Kamailio IMS (for free of
course), we sadly revoked that decision.

Currently, the Diameter-Stack in CDP is only TCP and NOT SCTP.  Of course,
you can do SIP signalling using SCTP, however this does not apply to
Diameter.

Thanks,
Carsten
