Hi Team, I want to know this reason - why kamailio only can connect to mysql using */tmp/mysql.sock <https://phonecom.atlassian.net/browse/VOIP-1760?atlOrigin=eyJpIjoiNzY1NjU4Y…>* and why it can’t use /run/mysql/mysql.sock Thanks and regards, Satya. -- * <https://www.ecosmob.com/> * *Disclaimer* In addition to generic Disclaimer which you have agreed on our website, any views or opinions presented in this email are solely those of the originator and do not necessarily represent those of the Company or its sister concerns.

evapi:message-received and state
by Alex Balashov 07 Nov '22

07 Nov '22

Hi, I am t_continue()ing a transaction inside of event_route[evapi:message-received]. The $evapi(msg) has quite a bit of payload that will be needed by the resumed transaction. Is there a good way to inject this data into the transaction scope externally? No [X]AVPs created in the event_route persist, of course, since the route is scoped outside of the transaction. I have been using htable to pass data into the transaction, keyed by the index and label. But, this strikes me as a kind of clumsy memory synchronisation anti-pattern. Is there a better way?

Kamailio Not Responding to Connections
by Carlos Escalona 07 Nov '22

07 Nov '22

Hello! I hope all of you are having a nice day. I would like some help. I recently had some troublesome events in my Kamailio setup, at a particular time of the day specifically after lunch when my platform's traffic spikes Kamailio suddenly stops responding to any connection and restarting it didn't fix the problem basically I have to restart the hardware to get out of that failed state. The only unusual log is the following: Oct 28 16:49:10 ip-172-32-16-97 /usr/sbin/kamailio[952]: ERROR: topos [tps_storage.c:615]: tps_storage_record(): failed to store Someone recently posted a problem that occurred when doing stress tests with the siptrace module active and the service that collects the traces was failing, I wonder if this may be the case because it is possible that something similar is happening in my case. Unfortunately, I don't have much more information since I had to implement a quick fix that mitigates the problem for now, but I would like to be able to go back to the previous configuration that seemed more appropriate. My plan is to test now that I have solved the problem I had with the traces service, but I wanted to know if anyone had experienced a similar situation.

Serial Forking on BYE message
by Ilie Soltanici 05 Nov '22

05 Nov '22

Hello, I have a challenge here to do serial forking, not when the call is failed on the first destination, but when the call is ended. So, the first will go to one destination, will be answered, and when it's ended the BYE message should be dropped and forward the initial INVITE to another location. Is that possible?

$Rp variable seems to contain wrong port
by Ross McKillop 03 Nov '22

03 Nov '22

Hi All, At the risk of possibly dragging up an old thread (https://lists.kamailio.org/pipermail/sr-users/2021-June/112791.html <https://lists.kamailio.org/pipermail/sr-users/2021-June/112791.html>) I’m seeing unusual behaviour where $Rp is still showing what I think is the ‘wrong’ behaviour, but given Daniel’s reply on the earlier thread I want to be sure this isn’t the intended behaviour. The thread above confirms that $Rp is not taken from the IP layer but is intended to give the attribute of the listen socket associated with the SIP traffic, which is fine and what I’m expecting, but in my case it doesn’t seem to be working this way. (I’ve tried with and without tcp_reuse_port=yes and tcp_connection_match=1 too just in case one of the above parameters has changed this behaviour) If Kamailio listening on multiple ports e.g. listen=tcp:10.30.22.73:7701 listen=tcp:10.30.22.73:7702 listen=tcp:10.30.22.73:7703 listen=tls:10.30.22.73:7801 listen=tls:10.30.22.73:7802 listen=tls:10.30.22.73:7803 And I use $fs to force the socket of an outbound message to one of the above before t_relay() it works as expected (with tcp_reuse_port it originates from the given port number above, without that set it will originate from a different ephemeral port even to the same destination, so $fs is working as expected) Then, in reply_route{} I have a simple line to add the port it was received on to the headers (I’ve also tried with $RAp) append_hf("X-Rcvd-Port: $Rp\r\n”); In every case, the reply seems to contain the *first* port of the protocol type (so in the above example every TCP reply irrespective of whether it is to 7701/02/03 will show $Rp 7701, and every TLS reply will show 7801) Any advice or insight anyone can offer would be much appreciated. Thanks, Ross

Siptrace and Kamailio "stress" test
by Igor Olhovskiy 03 Nov '22

03 Nov '22

Hello, Found an interesting scenario, maybe something could be done here. I have a siptrace module configured like modparam("siptrace", "duplicate_uri", "sip:<MY_HOMER_SERVER>:9060") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "trace_mode", 1) When Kamailio is under stress test (sipflood via OPTIONS/TLS), with this settings it transfers all flood to HOMER server. At some point Kamailio just stops accepting any new TLS connections. Turning off siptrace solves this issue. As I got, siptrace module is not changing protocol of the message (means not converting TCP/UDP) or so. Could it be possible, that at some point siptrace "eats" all TCP connections (especially if remote HOMER is down or not answering) which leads Kamailio to stop processing any new connections? And is it possible to send HEP traffic only via UDP to prevent this? Yes, sure other option is to trace only "legal" traffic -- Best regards, Ihor (Igor)

Pipelimit needs restart to reload values
by Duarte Rocha 02 Nov '22

02 Nov '22

Greetings, I've been using the pipelimit module and the pl_check function to control users rates in my proxy. if (!pl_check("$var(UserID)", "TAILDROP", "$var(UserRate)")) { pl_drop(); exit; } In this case $var(UserID) is the pipe and $var(UserRate) is the maximum rate. The value of the rate is retrieved on every call via query to a DB. If I change the UserRate value to 0 CPS on the DB calls are not rejected unless they go over 1 CPS. However, if I restart Kamailio all calls are correctly rejected. Why does this happen? Can I change this behaviour? Cheers, Duarte

Appending new branches via external means
by Alex Balashov 01 Nov '22

01 Nov '22

Hi, Is there a means of appending new branches from config script for a transaction which is already proceeding in the background, without using `tsilo`? That is to say, I have an async transaction which is resumed in an async worker and is t_relay()’d away to some destination. Meanwhile, I have learned about new destinations for it to try via an incoming registration, and would like to append additional parallel forking branches to that transaction, even though it is already proceeding. ts_append() does this for me; the issue I have is that it is mediated through a registrar, but I am not a registrar. My registrar is upstream, and my proxy is just a front-end to it. So, in essence, I require something like `tsilo` at a more general level, where contacts can be populated by some other mechanism rather than being learned via callbacks out of `usrloc`. Is there a way to accomplish this?

consume_credentials not working on PRACK?
by Benoit Panizzon 01 Nov '22

01 Nov '22

Hi List I noticed, that one of our CPE copies the Proxy-Authorization HF in almost all messages sent. As PRACK were not authenticated, those headers were potentially sent on to the destination disclosing the authentication username and realm. So assuming, if credentials are present, the client wishes them to be validated, I added: if (has_credentials("$fd")) { xlog("L_INFO", "$cfg(route): got $rm with credentials. Validate them!\n"); route(AUTH); } and in route[AUTH] I call: pv_auth_check() which returns 1 thus success upon which I use: if(!is_method("REGISTER|PUBLISH")) consume_credentials(); If the method is INVITE: Proxy-Authorization HF is removed by consume_credentials() if the method is PRACK: Proxy-Authorization HF is still present on the outbound leg.
