TOPOS, 183 (before a 200OK) and SIP INFO
by Giovanni Tommasini 28 Apr '22

28 Apr '22

Hi kamailiers, I ask your help for a strange situation with topos, 183 (before a 200OK) and SIP INFO My topology is kamailio in front of asterisks; so kamailio has 2 interfaces (1Public to talk with customers and carriers and 1 Private to talk with asterisk). In the image: - the first column is the customer - the second is the public interface of kamailio - the third is the private interface of kamaiio - the fourth is asterisk As you can see in the image, the customer send an INVITE and the carrier give back the IVR messages in a 183 (before a 200OK) asking for an IVR selection. The customer (configured to use SIP INFO) types a key and sends in INFO, but as you can see kamailio sends the INFO to himself to private interface instead of sending it to asterisk as if the contact that handled topos contained incorrect information. [image: Schermata 2022-04-26 alle 19.40.32.png] - If the customer is configured with a RFC2833 - or if the IVR messages is not in a 183 but is sent after a 200OK - or if I disabe TOPOS *all works fine* I used kamailio 5.5.3, I also try to upgrade to 5.5.4 but nothing change Maybe could be connected with https://github.com/kamailio/kamailio/issues/2344 https://github.com/kamailio/kamailio/issues/1077 Could be a kamailio bug for this particular situation or am I getting lost in a glass of water? thanks a lot cheers Giovanni Tommasini *evoseed s.r.l.* phone: +39 340 11 28 800 mail: giovanni.tommasini(a)evoseed.io site: evoseed.io address: Via Lucrezio 13, Trieste Italy

Kamailio functionality clarification - call forwarding no replay (call is ringing but not answered)
by Pavel Veselovsky 28 Apr '22

28 Apr '22

Hallo all, I would need help with Kamailio. I hope, you can give me some hints. I would like use Kamailio for CFNRy feature call forward no replay, i.e. - call is forked to multiple destination - 180 is received, call is ringing, but not answered, no 200 OK is received from destinations - after predefined time (CFNRy timer), the specific branch has to be rerouted to another destination Expected behaviour is described in this flow: [image: image.png] My current behavior: - Kamailio TM module is involved for parallel forking ( https://www.kamailio.org/docs/modules/stable/modules/tm.html#:~:text=1.-,Ov… ) - all branches are CANCEL-ed, it is not possible send CANCEL just to one specific branch [image: image.png] My questions: - is it possible to CANCEL just specific branch of parallel forked calls? - is it possible start timer just for specific branch? - do you think is it possible implement this feature with Kamailio? Thanks a lot in advance for any comments. Pavel.

Modify session name in SDP
by ZZ Wave 28 Apr '22

28 Apr '22

Hello. Kamailio 5.2.1, Debian 10. I need to change session name (s=) in SDP before relaying it to next hop, and for unknown reason I can't do it with virtually any TEXTOPS function, everything replace*, subst*, *body*... For example this from TEXTOPS documentation: subst_body('/^s=(.*)/s=root/') just before 'final' t_relay(). Either Kamailio just adds "s=root" to SDP leaving first "s=" intact, or adds just "root", or does nothing. Also I've tried msg_apply_changes() before and after these manipulations, still no result. Is it possible to make this in Kamailio without source code modification?

High performance
by Muborakshohi Masoud 27 Apr '22

27 Apr '22

Hello! I have kamailio 5.5 configured with digest authentication. DB Mysql, 2 rtpengine one on the same server with kamailio, the other is separate. Rtpengins work in bridge mode, internal/external/external-ipV6. Kamailio listen 3 address: internal/external/external-ipV6 work in mixed mode: ipV4-ipV4, ipV4-ipV6, ipV6-ipV6. OS Debian 10, CPU 1 core, Ram 4gb, Disk not ssd. internal address is used for the gateway model of the connection to the PSTN. Before sending a call to PSTN, a request is sent to Billing by Diameter (request over the network, ims_charging ), Billing responds in the region of 10-17 milliseconds. usrloc db_mode = 0; UAS contacts are received according to the PUSH scheme (we send PUSH via http and get a REGISTER). children = 8 for each; When running synthetic tests with sipp, I get 36 cps as a maximum, but there are a lot of retrans. This is a test environment. Product: I plan to get 100 cps; 20k concurrent calls, hardware will be 128GB RAM ddr4-2400; Intel Xeon Silver 4216, Optane SSD. 2 such servers, kamailio/rtpengine are configured exactly according to the scheme of the test environment. Question: Can you please tell me how many children, shm/pv do I need? Is it worth going in the direction of asynchrony, or is the standard one enough for my purpose? I will be very glad for any help. Thank you! -- Отправлено из Mail.ru для Android

LCR issues (request_uri)
by Antoine DEBARRE 26 Apr '22

Hi, I'm trying to use LCR with kamailio v5.5.4 gw, rule and rule_target are stored on mysql. for lcr rules, do you know if prefix is mandatory ?

Local Registration Cache
by Linux Vince 26 Apr '22

26 Apr '22

Hello, I am trying to implement scenario described in this thread by Daniel-Constantin Mierla. I am able to cache registration using save but i am not able to handle unregistration. Unregister function of registrar module is not available in onreply routes and I cannot unregister until upstream registrar returns 200 OK on Expire 0 message. Is there any workaround to fix this? Thanks,

SSL errors with websocket clients
by Vinicius Kwiecien Ruoso 22 Apr '22

22 Apr '22

Hi all! How are you? I have a kamailio instance and some users are having issues connecting via websocket using TLS. The logs show SSLv3 errors. Cannot find why that error would show up if SSLv2/3 is not enabled. Double checked it via SSLLabs that only TLSv1.2 is allowed in the service. Error sample: ``` 15(36) ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown 15(36) ERROR: <core> [core/tcp_read.c:1512]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7fafc8768190 r: 0x7fafc8768278 (-1) ``` This instance has close to 400 websocket connections opened during the day. I have a high log level enabled. I was not able to identify any reason why this happens. The certificate is a Letsencrypt certificate. The issue is that sometimes clients have a hard time connecting to the websocket and that maybe related. Below are a few more details about the config. Please let me know if you have any pointers on how to debug those connection issues. 8<----- TLS config: modparam("tls", "tls_method", "TLSv1.2+") modparam("tls", "verify_certificate", 0) modparam("tls", "require_certificate", 0) modparam("tls", "low_mem_threshold1", 0) modparam("tls", "low_mem_threshold2", 0) modparam("tls", "private_key", "/etc/certs/tls.key") modparam("tls", "certificate", "/etc/certs/tls.crt") version: kamailio 5.3.9 (x86_64/linux) 8<----- This is related to the issue https://github.com/kamailio/kamailio/issues/3085 (as pointed out it is not a problem in Kamailio code). Thanks, Vinicius

How to disable video in invite with both audio and video
by Simone de Blasiis 22 Apr '22

22 Apr '22

Hello to everyone, we have a Kamailio 5.5 + RTPEngine deployment. Some devices will send an invite with both audio and video in the offer and we are trying to disable the video portion of the invite by either setting the video port to 0 or by setting a=inactive in the video portion of the SDP packet. We know that sdpops has a function that would be able to remove the video portion but it violates standards so we can't use it. We need to disable the video in the SDP offers because one of the pstn providers we are using doesn't accept invites that contain a video offer. I've spent days searching but I can't find an obvious way of achieving this. We were originally doing it with textops but we've been having some issues where the sdp wouldn't be modified correctly in reinvites after the original call is in place so we're looking for alternatives. Can someone please help us? Thanks in advance Simone de Blasiis
