Kamailio Configuration Help
by P. White 16 Aug '22

16 Aug '22

Hi All, Really sorry to bother everyone, but if possible, can I ask for a little help? I've been attempting to get Kamailio configured and working for some considerable time now (read: Years of occasional tinkering, and weeks of recent dedicated evening work) -- all without success. I have a sip trunk from sipgate, with two PSTN numbers assigned. My local network has a static external IP, with an internal private network. Currently I have Kamailio running within the intenal network along with two physical sip telephones (gigaset and an old grandstream), although I do have the option to put kamailio within a DMZ if necessary. Would anyone have a working config file that they could share please, permitting incoming and outgoing calls? With grateful thanks, Phil

Change reply code reason other than using change_reply_status
by Patrick Karton 12 Aug '22

12 Aug '22

hello is there a way to change reply code reason other than using () function. because the first parameterc of change_reply_status needs to be a constant so i can not use pseudo var for first argument of that function. so i use change_reply_status_code to change to code with a pseudo. but i would also to change the code reason.

remove_hf() does not remove the complete line
by Bernd Krueger-Knauber 11 Aug '22

11 Aug '22

Hi, I tried to remove a Via header line with: remove_hf("Via"); Original I have this 2 lines: Via: SIP/2.0/TCP xxx.xxx.xxx.xxx;branch=z9hG4bK370b.21720bb33c4f8264fde4e7994d288a57.0;i Via: SIP/2.0/TCP yyy.yyy.yyy.yyy:53967;received=yyy.yyy.yyy.yyy;rport=53967;branch=z9hG4bKPjxb0bdb2c9624076815f12937cc9e51d;alias If I insert remove_hf("Via"); in the cfg, I get: Via: SIP/2.0/TCP xxx.xxx.xxx.xxx;branch=z9hG4bK370b.21720bb33c4f8264fde4e7994d288a57.0;i ;received=yyy.yyy.yyy.yyy;rport=53967;branch=z9hG4bKPjxb0bdb2c9624076815f12937cc9e51d;alias Doesn't mattter if the command make sense or not, the result, in my opinion, is wrong. The INVITE packet has now an invalid header line. Any ideas? version: kamailio 5.6.1 (x86_64/linux) Best regards, Bernd

Kamailio has unconfined processes
by HimaBindu G 11 Aug '22

11 Aug '22

Hi, Problem Description: Customer security scan returned unconfined services on Kamailio. Unconfined processes run in unconfined domains Rationale: For unconfined processes, SELinux policy rules are applied, but policy rules exist that allow processes running in unconfined domains almost all access. Processes running in unconfined domains fall back to using DAC rules exclusively. If an unconfined process is compromised, SELinux does not prevent an attacker from gaining access to system resources and data, but of course, DAC rules are still used. SELinux is a security enhancement on top of DAC rules - it does not replace them Solution Investigate any unconfined processes found during the audit action. They may need to have an existing security context assigned to them or a policy built for them. Notes: Occasionally certain daemons such as backup or centralized management software may require running unconfined. Any such software should be carefully analyzed and documented before such an exception is made. See Also https://workbench.cisecurity.org/files/2485 For Kamailio ====== The command returned : 00 kamailio 00 kamailio 00 kamailio 00 kamailio 00 kamailio 10 kamailio 10 kamailio 10 kamailio 10 kamailio 00 kamailio 00 kamailio 00 kamailio 00 kamailio 33 kamailio 33 kamailio 33 kamailio 32 kamailio 17 kamailio 16 kamailio 33 kamailio 00 kamailio 00 kamailio 03 kamailio 05 kamailio 18 kamailio 17 kamailio 18 kamailio 18 kamailio 07 kamailio 00 sleep is any security context available to assign kamailio processes ? theses services can be run as confined services ? Please suggest us with resolution, thanks in advance. Thanks & Regards, Hima Bindu.

Kamailio World Conference - Sep 7-8, 2022 - Online
by Daniel-Constantin Mierla 10 Aug '22

10 Aug '22

For the 3rd year, we are planning an online version of Kamailio World Conference! At the beginning of 2022, the situation was not clear in terms of whether pandemic would decrease enough in intensity and we would be allowed to organize an on-site event late spring/beginner of summer, when the usual Kamailio Conference took place in Berlin, therefore we chose the safety path. But we hope that next year we will return in-person to the beautiful Berlin city center! The event this year, to happen in 4 weeks from now (Sep 7-8, 2022), follows the structure from previous edition, being two afternoons with presentations about Kamailio, sharing technical solutions and open discussions, allowing the community to interact and reconnect. The website of the event: - https://kamailioworld.com/k10-online/ There is no registration required, the event will happen on live video conferencing, also streamed to youtube. A text chatting channel will be made available as well. If you want to present, just send me the title and a short description -- we encourage community members to step forward and share their knowledge. It has to be related to Kamailio and fit within a 30min slot (including the questions). The agenda will be released in the near future. The event will be used also to celebrate 21 years of Kamailio project development, first commit being done on Sep 3, 2001. Two other major celebrations for 2022 to make the party bigger: - 20 years of open source for the project -- after one year of internal development, GPL was added on Sep 19, 2002 and source code was released to public - the 10th edition of Kamailio World Conference Book the dates in your agenda! I am looking forward to a very interesting event and (re-)connecting with many of you! Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

set source port of TCP socket in Contact header
by Maarten Ureel 09 Aug '22

09 Aug '22

Hello I want to set the correct source port in an outgoing message over TCP. Is it possible? I can't find a pseudo-variable for this. Currently we have no port number in the contact header, and the other party is sending their BYE to port 5060 instead of to the source port from which the outgoing TCP connection was made. Regards Maarten

Syncing Registration Database across Kamailio Pairs
by harneet singh 09 Aug '22

09 Aug '22

Hi Experts, We have been using Kamailio in an Active/Standby Pair(with Keepalived under the rugs moving the single Virtual IP to access the Active Kamailio) for sometime now. *Kamailio also acts as a Registrar for our webrtc endpoints. * It has been serving the purpose pretty well and now we have a requirement where we need to be syncing the Registration DB between Two Pairs of Kamailios. Kamailio-Active(*Pair 1*) -------- Kamailio-Standby(*Pair 1*) || Kamailio-Active(*Pair 2*) -------- Kamailio-Standby(*Pair 2*) We generally keep the counterpart in the same Pair as a notifier( *modparam("dmq", "notification_address", "sip:PEER1_IP:5060")* ) so as to sync the dialogs and the userloc data too( *modparam("dmq_usrloc", "enable", 1) * ). In order to achieve the said requirement with the other Pair, we added another "*notification_address*" in the kamailio cfg. At this point, we ran into weird issues. *1. *With Kamailio ver *5.3.2, *the subsequent *notification_address *line in the cfg file, seemed to be overriding the previous one. Hence we see only the latter peer in the dmq list nodes. Example: modparam("dmq", "notification_address", "sip:*172.27.45.77* :5090") modparam("dmq", "notification_address", "sip:*172.27.45.200* :5090") In this case, the "*kamcmd dmq.list_nodes*" would show the local Machine and 172.27.45.200 as the only nodes in the output, ie *172.27.45.77 is not showing up at all,* which is problematic, since the local machine(172.27.45.243 in our case) would not been able to send any dmq sync info to its peer(172.27.45.77) in the same Pair. To see if the above issue might have been addressed in later release, we upgraded to the latest Kamailio ver *5.6.0* *To our respite, the above issue no longer exists in the new version*(though not sure which immediate release after v 5.3.2 it would have been initially fixed.) This is where we have a new issue explained below: *2. *The registration data does get synced to the peer Kamailio in the same Pair, and also to the Kamailio instances in the other Pair. However, the *Socket* Parameter in "*kamctl ul show*" output shows *[not set] *even on the side where the websocket connection actually exists. [root@localhost ~]# *kamctl ul show * { "jsonrpc": "2.0", "result": { "Domains": [{ "Domain": { "Domain": "location", "Size": 1024, "AoRs": [{ "Info": { "AoR": "9008077221", "HashID": 1952082106, "Contacts": [{ "Contact": { "Address": "sip:Harneet_qifir@172.24.58.210", "Expires": 159, "Q": -1, "Call-ID": "vfli2uv8du3ppda73q5ppe", "CSeq": 106, "User-Agent": "EngageDigital", "Received": "sip:172.27.44.252:60070;transport=ws", "Path": "[not set]", "State": "CS_NEW", "Flags": 0, "CFlags": 0, * "Socket": "[not set]", <<<<<<<<<<<<<<<<<<<<<<* "Methods": 7071, "Ruid": "uloc-62f26e3b-2677-1", "Instance": "<urn:uuid:4fbd3e96-b4de-497b-886d-1ca8ffa016a4>", "Reg-Id": 1, "Server-Id": 0, "Tcpconn-Id": -1, "Keepalive": 0, "Last-Keepalive": 1660063892, "KA-Roundtrip": 0, "Last-Modified": 1660063892 } }] } } ], In order to confirm that the socket actually exists on this Kamailio instance, I am pasting the below outputs from the same machine, where ws dump and even the native netstat confirms that. [root@localhost ~]# *netstat -tunelap | grep 60070* tcp 0 0 172.27.45.199:8080 172.27.44.252:*60070* *ESTABLISHED* 994 17322355 16230/kamailio [root@localhost ~]# *kamcmd ws.dump* { connections: { 1: ws:172.27.44.252:*60070* -> ws:172.27.45.199:8080 (state: *OPEN*, last used 24s ago, sub-protocol: sip) } info: { wscounter: 1 truncated: no } } We do need to distinguish the actual Kamailio instance where the websocket connection actually exists, so as to route the call ahead from the same instance, or if it does not exist(and it's merely a sync'ed registration data received over DMQ Channel), then the Kamailio should route the call ahead to the Kamailio instance in the other Pair, which can then route it ahead to the Registered webrtc endpoint. We were hoping to use the Socket Parameter output, but for the said problem, unable to use the same as an indicator. *So what would be the best way to identify which Kamailio has the websocket connection with the Actual endpoint*? Should we rely on the output of netstat or ws.dump to infer that? I mean this needs to be done in kamailio.cfg for each call, so want to know the best way, or if there is completely different approach that can be suggested? Apologies for the long email, but any pointers will be much helpful.

recompute distribution list
by David Villasmil 08 Aug '22

08 Aug '22

Hello guys, Is it possible to have dispatcher recompute the distribution list? i.e. one server goes down, all traffic for that server goes to the next one, doubling traffic on that one. Is there a way of, when a host becomes unreachable, recompute the whole list? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337
