Don't worry about this I found the hash_algo rtpengine modparam option , and crc32 seems to do the job of more even distribution.

rtp engine weighted distribution

Hi, I wonder if you could offer some insight how to fix my issue I have 6 rtpengines and I wanted to priortitse the first 2 in the local network, so I set the weight to those to be 1000 modparam("rtpengine", "rtpengine_sock", "udp:10.0.0.1:2223=1000 udp:10.0.0.2:2223=1000 udp:10.0.2.3:2223 udp:10.0.2.4:2223 udp:10.0.3.5:2223 udp:10.0.3.6:2223") Kamailtio seems to be favoring 10.0.0.1, with only 1% of media sessions going to 10.0.0.2, is there something I'm missing?

How to correctly generate a 181 Call is being forwarded reply?
by Benoit Panizzon 02 Dec '25

02 Dec '25

Hi Gang One of our IC partner complained we do not correctly indicate calls being forwarded by sending a 181 Call is being forwarded reply back to the caller according to RFC5359. So something like sl_send_reply("181","Call is being forwarded"); have $ru point to CFW destination. append_hf("Diversion: .... record_route(); route(RELAY); I don't seem to get it working as expected - still trying to figure out what and where the call fails. I have cycled through sl_send_reply() which looks right as I guess 181 is always sent stateless, sl_reply() and t_reply(). Which one would be the right function to use? Is there anything else I could have missed.

missing column in mysql
by Alexis Fidalgo 01 Dec '25

01 Dec '25

Hello all, this mail is just to let you know about something i found, sadly i was in a maintenance window so i forgot to copy which column it was. Theres a column missing or misname in the acc mysql module in 6.0.4. steps i did 1. configured kamctlrc with the mysql host+credentials (mysql was completely empty, only a new user created to be used with kamailio) 2. created the tables with kamdbctl create 3. enabled mysql and acc mysql in kamailio.cfg 4. used only setflag with 1 in some points of the call 5. placed a call When kamailio tries to insert in the acc table there’s an error for a missing or misnamed column in the mysql and the insert fails. all of described steps were made using ghcr.io/kamailio/kamailio:6.0.4-bookworm <http://ghcr.io/kamailio/kamailio:6.0.4-bookworm> container image with the following detail ╰─# docker image inspect ghcr.io/kamailio/kamailio:6.0.4-bookworm [ { "Id": "sha256:119a8949971f70bb69c7286650fdee8ce9ef33ae81bad798bf20a81f1daad249", "RepoTags": [ "ghcr.io/kamailio/kamailio:6.0.4-bookworm" ], "RepoDigests": [ "ghcr.io/kamailio/kamailio@sha256:119a8949971f70bb69c7286650fdee8ce9ef33ae81bad798bf20a81f1daad249" ], "Comment": "buildkit.dockerfile.v0", "Created": "2025-11-06T12:04:58.852349663Z", "Config": { "Env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin", "REFRESHED_AT=2025-11-06", "SHM_MEMORY=64", "PKG_MEMORY=8" ], "Entrypoint": [ "/bin/sh", "-c", "kamailio -DD -E -m ${SHM_MEMORY} -M ${PKG_MEMORY}" ], "Volumes": { "/etc/kamailio": {} }, "Labels": { "org.opencontainers.image.authors": "Victor Seva <linuxmaniac(a)torreviejawireless.org>", "org.opencontainers.image.created": "2025-11-06T12:03:50.575Z", "org.opencontainers.image.description": "official Debian base image", "org.opencontainers.image.licenses": "GPL-3.0", "org.opencontainers.image.revision": "e17c5b6ae7094f9e4842b54d260b2596f91baad4", "org.opencontainers.image.source": "https://github.com/kamailio/kamailio-docker", "org.opencontainers.image.title": "kamailio", "org.opencontainers.image.url": "https://github.com/kamailio/kamailio-docker", "org.opencontainers.image.version": "6.0.4-bookworm" } }, "Architecture": "amd64", "Os": "linux", "Size": 394440142, "RootFS": { "Type": "layers", "Layers": [ "sha256:e7278a7fd0ae725fc048bfd0a36c69c162b1d8530a39f49c977cfb8454857c3b", "sha256:14e4fdaa2b777103ab080a7eee7dfeff316580c46f5152e4cf3fdb781884920c", "sha256:74581eabb88cf4a1cc38a6b303ea2d804ce943f92e1d7f5de77d3bafe38fb32d", "sha256:696484fe1e2c0a1cd56beb483c7f4ac29811dd3f45c42b514796ab9559459816", "sha256:023fef7ed12af21069a6e56c933dfbc1aad6ad422eb75e34f08e084c1433ea8f" ] }, "Metadata": { "LastTagTime": "2025-11-29T22:32:21.299030421Z" }, "Descriptor": { "mediaType": "application/vnd.oci.image.index.v1+json", "digest": "sha256:119a8949971f70bb69c7286650fdee8ce9ef33ae81bad798bf20a81f1daad249", "size": 1458 } } ] ╭─root@teco-01 ~ ╰─#

topoh breaks SIPS with PJSIP if PJMEDIA_SRTP_MANDATORY is set
by Mathias Schneuwly 01 Dec '25

01 Dec '25

Hi I have a question related to topoh. We are running Kamailio in version 6.0.2 with topoh enabled. The PJSIP based softphone is unable to establish a call with SIPS and SRTP if we use "PJMEDIA_SRTP_MANDATORY" in PJSIP. PJSIP complains about "Secure dialog requires SIPS scheme in Contact and Record-Route headers, ending the session". The other side is sending "Contact: <sips:620150@10.165.44.117:59686;transport=tls>", but topoh modifies the contact header to "Contact: <sip:127.0.0.8;line=sr-avdFaQDvhUxGrqtxhqxThq-ZnUy6nUzGrQDZmqa1rUf6a0JTaLt4aoyV2EGQ>" without sips scheme and without transport=tls. PJSIP then refuses to establish the call and sends immediately a BYE. If topoh is disabled, the call is successfully established. Is it somehow possible to tell topoh to keep the scheme or transport=tls if the other side provided it? Thanks for your help Best regards Mathias
