String Transformation Question
by Sam Ware 10 Jan '20

10 Jan '20

We are receiving traffic with a tech prefix. We want to be able to use a # (hash tag) for the separator for the tech prefix and the remote user ($rU). I was using the s.select transformation before when using * for separator, but I get an error because it appears that it being interpreted as a comment. Any suggestions? Example: ## How I was doing it with the * $avp(techprefix) = $(rU{s.select,0,*}); ## How I tried and got an error for the hash tag $avp(techprefix) = $(rU{s.select,0,#}); -- … [View More]

caching 404 responses
by Krzysztof Drewicz 10 Jan '20

10 Jan '20

Hello would like to see if I'm not reinventing the wheel: scenario: some old powerdialler/predictive calls kamailio as call dispatcher, kamailio then dials carrier. But this dialler does many calls to the same B number with 404 response (from carrier) in short (retry is < 600s) time, so no need to bother PSTN/carrier with retry. Should I simply use htable, cache 404 hit, use some reasonable value modparam("htable", "db_expires", 1) put there like 600 s TTL or something like that? Any … [View More]

TCP packet bundling
by Alex Balashov 09 Jan '20

09 Jan '20

Hi, I wanted to get clarity on a rather basic question: When using Kamailio with TCP, is it possible to end up with fragments of multiple SIP messages in a single "on-the-wire" packet? >From what I understand, the purpose of Kamailio's setting TCP_NODELAY is to prevent such bundling--as much as it is possible to control the fragmentation/packetisation behaviour of the transport protocol from a user-space application. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-… [View More]

Huge DB load while using location and registrar module (save()).
by Voip support 09 Jan '20

09 Jan '20

Dear Community, I am facing an issue with using the usrloc and registrar module to save registration informations in database. It works for me but when tested yesterday with around 1500-1600 users i got a lot of queries on database mostly SELECT. I figured out that changing db_mode to 0 resolves the issue because it works totally in memory (almost no select query on DB). So i think its location module. I tried db_mode=3 and db_mode=2 but both create a lot of load on database. The only … [View More]

Releasing Kamailio v5.3.2

Hello, not so many fixes since the release of 5.3.1, but it looks enough to release a new minor version from branch 5.3.

Parsing exception when "user=phone" is present

possible TCP deadlock (tls again?) // pike module not releasing IPs
by Aymeric Moizard 08 Jan '20

08 Jan '20

Hi List, History: * In the past, I had deadlock which was, most probably, related to ssl1.1. We have discussed this issue, and a fix is supposed to workaround the issue that was detected. * With latest 5.2.X, I have experienced ONCE a similar behavior with TCP and TLS being mostly stuck. I have not been using this version much, but the fix was supposed to be in the core of kamailio. The status of the server this night: * I'm today running version: kamailio 5.3.1 (x86_64/linux), * Installed … [View More]on stretch using http://deb.kamailio.org/kamailio53 repository. * This versions use libssl1.1 * A user reported that he can't connect with TCP * An average of 5000 IPs per 10 minutes are being banned by the pike module (could be twice the same) Yesterday/Today: * at the end of the outage, I had 2479 IP in my ipban htable. (which is equivalent to my statistics showing 2 bans/IP every 10 minutes = 5000) * looking at my logs, it appears that most (ALL?) ip being banned... are my regular users. * looking at my logs, I can't understand why pike would block them. This is a graph for statistics on my service for the last 24 hours: https://www.antisip.com/sip-antisip-com-register/status2.html Yesterday, at 22:18:39, kamailio started to BAN some IPs. 52 IPs were banned in a period of 10 minutes. I can confirm this from my logs. My pike configuration is this one: modparam("pike", "sampling_time_unit", 2) modparam("pike", "reqs_density_per_unit", 64) modparam("pike", "remove_latency", 4) When detecting the issue, this morning, I typed: $> sudo kamctl stats $> sudo kamcmd htable.dump ipban //FAILURE (answer too large...) $> sudo kamctl trap Then, I started an agent with TCP and it worked...??? Then, a few seconds, may be a minute after: $> sudo kamcmd htable.dump ipban //SUCCESS and shows 2479 banned ip. and... everything is back to normal in a few minutes. I haven't restarted kamailio, and all statistics are as expected, as usual. Thus, it looks that " sudo kamctl trap" has triggered something. I already experienced a similar behavior -when testing my ssl1.1 deadlock last year-. 2 questions: 1/ I beleive my "pike" configuration should not ban users. Is my pike configuration wrong? As an example, pike has banned an IP sending one message/second. I believe my configuration should accept that? 2/ Could there still be a TLS issue with libssl1.1? This is the result of the "kamctl trap": https://sip.antisip.com/kamailio-pike-or-tls-issue-13-12-2019.kamctl-trap Sorry for the long story & hoping to find a long term solution or at least a workaround!

Hi all. I have Kamailio with 2 addr: kamailio_external_ip - for client interconnect kamailio_internal_ip - for local media server interconnect Like this: client - kamailio_external_ip - kamailio_internal_ip - media_server "topos" module hide sip headers for both "client" and "media_server" side. Is it true: with topos i can't hide headers only for the "client" side and show them for the "media_server"? I want full header set visible for the "media_server", but only kamailio_external_ip … [View More]

rtpproxy_manage() doesn't recognize SDP when Content-Length is not present
by Leonid Fainshtein 22 Dec '19

22 Dec '19

Hi, According to RFC-3261 p.20.14, the Content-Length header field must be present only if a stream-base transport protocol (such as TCP) is used. Therefore, in the case of the UDP transport protocol, this field is optional. Unfortunately, the rtpproxy_manage() function in Kamailio v.5.2.5 doesn't recognize the SDP body when the Content-Length header field is not present: Dec 22 08:58:34 pbx kamailio[13456]: 4(13488) WARNING: {1 1 INVITE wrjxwyuke5ukvvwwxd00zwtu0ktfuzuf(a)10.18.5.64} sanity [… [View More]

Hi Team, We are using your product Kamalio in Call Recording services. We are planning for Performance testing of our recording system. Currently we have bypassed Twilio and Kamailio.

TLS testing (with sipp)

Hi, I'm trying to construct an end-to-end encrypted signalling test through our setup. I thought I could use sipp for that, as it supports TLS according to the man page. However, when I try to run it, I get this error: FI_init_ssl_context: SSL_CTX_use_certificate_file failed. I searched the web; however, all similar questions end up without answers.

kamailio 5.2.5 wrong send socket on a mhomed proxy.
by Vitalii Aleksandrov 19 Dec '19

19 Dec '19

Hi, kamailio 5.2 branch has a commit 09ac3e47ef79dbd599b7dec5b84ae3b792f025ed cherry picked from master branch. It makes sense for master because get_send_socket2() behavior has changed and function became started and also there were some patches to propagate connection it to uac structure. 5.2 kamailio takes the first interface for TCP/TLS/WS connections and then finds existing tcp connection matched by ip:port, but when the patch is applied connection lookup fails and kamailio can't forward in-dialog messages.
