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, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB 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.
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 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.
