Hi Carsten.
That is ok. We can go with TCP for now. Do you have any idea of when
will SCTP be implemented in Kamailio ? Few months or year may be.
I think I found a bug during the diameter capability exchange that might
be caused by buffer overflow or bad memory management but I will post in
another thread.
Regards.

Hi,
we are using SCTP in one of our commercial deployments, but we haven't
found the time yet, to port that part back to the official repo. This
may take some time, but sooner or later we will add this to the
open-source Kamailio.
Thanks,
Carsten

Hi all.
This question has already been asked in the past:
https://lists.kamailio.org/pipermail/sr-users/2015-July/089083.html
But I don't see any answer if this is supported.
Can you tell me if it is possible to enable the IMS to talk to HSS using Cx
(diameter) over SCTP ?
In the source code (kamailio/src/modules/cdp/configparser.c) I can see only
these parameters for Peer node:
- FQDN
- Realm
- port
- src_addr
but there is no protocol parameter.
I tried with the example VM here:
https://www.kamailio.org/w/2016/02/kamailio-ims-getting-started-box/
I started all services and dumped the traffic with wireshark. The transport
is TCP.
This VM uses an older version of kamailio:
====================================================
kamailio -v
version: kamailio 4.3.4 (x86_64/linux) 583dc0
flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS,

poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.
id: 583dc0
compiled on 21:01:04 Dec 1 2015 with gcc 4.9.2
====================================================
So I installed the latest stable but it seems it also uses TCP.
Regards.
