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.

Authentication: Is it possible to ignore realm? How to avoice unnecessary challenge because of changed realm?
by Benoit Panizzon 01 Nov '22

01 Nov '22

Hi As mentioned in the last email, we have a CPE which adds credentials to any request so I would like to validate them. We use $rd as realm. Let's use example.com as example. During the initial INVITE, this works as expected. I try to only show the headers I think are relevant to the issue I face. INVITE sip:1234@example.com SIP/2.0 Proxy-Authorization: [...] realm="example.com" Contact: <sip:9876@192.168.1.1:5060> Authentication user in realm "example.com" == $rd is validated and accepted. The connection is establised: 200 OK From: <sip:9876@example.com>;tag=1 To: <sip:1234@example.com>;tag=2 Contact: <sip:1234@192.168.7.7:5060> The caller terminates the connection: BYE: sip:1234@192.168.7.7:5060 SIP/2.0 From: <sip:9876@example.com>;tag=1 To: <sip:1234@example.com>;tag=2 Proxy-Authorization: [...] realm="example.com" Performing: $var(authres) = pv_auth_check("$rd", "$avp(authsecret)", "0", "1"); fails wirh result -5 as there is no authsecret for realm "192.168.7.7" So an unnecessarey challenge is issued: SIP/2.0 407 Proxy Authentication Required To: <sip:1234@example.com> From: <sip:9876@example.com> CSeq: 3 BYE Proxy-Authenticate: Digest realm="192.168.7.7" To which the client replies with the changed realm: Proxy-Authorization: Digest username="****",realm="157.161.7.7",[...] and succeeds authentication. Is there a way to accept 'any' realm? Or to avoid this unnecessary change of realm just because the remote site submitted a domain realm in the contact header?

SIP routing per MSISDN
by Anthony Blandin 30 Oct '22

30 Oct '22

Hello, I need to route SIP INVITE towards a specific node based on the MSISDN of the Request URI. I saw that the dispatcher module should be able to make this with the function ds_select_dst and the algorithm "hash over request-URI user" but I don't understand how the routing is done if we can't associate the request-URI user with the destination address in the dispatcher DB. Maybe my understanding of this module is wrong. Could you help me to achieve this? Thanks Anthony

Kamailio sending response to source IP and port from Via ?
by Chaigneau, Nicolas 27 Oct '22

27 Oct '22

Hello, I'm using Kamailio in stateless mode to send redirect responses. I've noticed that the responses are sent to the packet source IP address, and to the port found in the Via header. I'm a bit confused. I was expecting the response to be sent to the address and port found in the Via header. Is it the expected behaviour ? I'm using Kamailio 5.5.2. Thanks for your help !

No REGISTER sent to third party AS from scscf
by Anthony Blandin 24 Oct '22

24 Oct '22

Hi Community, I am using scscf from Kamailio and I need that scscf sent a REGISTER to a third party AS during the registration phase. When scscf received a new registration, no REGISTER is sent to the AS. SAR-SAA is well processed but only 200 OK is sent for the REGISTER to the pcscf. REGISTER is well sent to the AS only for Re-Registration or De-registration. Do you have any idea to handle this case? Regards Anthony

Dialog Module: How to get two different dialogues if a call is looped through kamailo (call forwarding scenario)
by Benoit Panizzon 21 Oct '22

21 Oct '22

Hi Using the dialog module to generate CDR for billing. We have this situation: Kamailio 'routing' instance, where dialog is used and billing happens. Kamailio 'register' instance. IC is connected to the routing instance. Customers register to the register instance. Call originates from 'A' via IC through routing instance to register instance and rings customer 'B'. This times out and 'call forwarding' is engaged by sending the call back to the routing instance with a new RURI containing the call forwarding destination 'C'. An appropriate 'no-answer' Diversion Header is added. Now we need two different CDR for this scenario (add more CDR if the call is forwarded multiple times) One from the A to B leg to bill termination fee to the IC carrier. One from B to C to bill the forwarded call with destination 'C' to customer B. The issue I now face is that I only get the kamailio routing instance to generates one dialogue from B to C despite handling two separate connections. How could that challenge be solved?

After changing instance type for kamailio server in aws log file is corrupted

Hello guys, after changing instance type from t2 to t3a for kamailio server in aws log(/var/log/kamailio.log) file and some other files are corrupted and I can not touch,delete,create or anything and when kamailio start receiving traffic it crashed. Is there any particular reason for this? Basically on t2, they are under /dev/sda1 and /dev/xvda. Under t3 they are nvme disks (biggest part of the speed increase), so they are under /dev/nvme1n1. Note: once I rollback to t2 everything is working as expected.

Issue with duplicite SIP messages in traffic loop
by Michal Popovič 19 Oct '22

19 Oct '22

Hello, I am trying to configure kamailio to use external antifraud protection using so called "traffic loop" when call is forwarded to external SIP proxy that would response even with same INVITE back or with error message if number is fraud. schema: PBX -> kamailio -> traffic loop -> kamailio -> carrier Kamailio in second and fourth step is the same. Issue is that if kamailio receives same INVITE back to I would like to forward to next carrier it is possible, but kamailio struggles with transaction handling. If ACK message come from PBX, kamailio will correctly forward it to traffic loop but when it comes back, function t_check_trans is failed and I cant relay it. Only workaround is to use send() message, but that causes deny of BYE message from carrier. My question is following: Is it possible to register two different transactions states for same message? If yes how? If no, would it help to send and receive messages on another network port or not? Thank you, Michal

IMC module
by Giovanni Iamonte 19 Oct '22

19 Oct '22

HI, I am facing a problem related to the IMC module. I have installed kamailio 5.2.x and I tried to list the members of a room-qsipchat. In my test environment the kamailio.cfg file it is very basic, the kamailio server listen on tcp=192.168.100.192:15006 the client run on a PC with IP address 192.168.100.156 the imc outbound_proxy is set modparam("imc", "db_url", DBURL) modparam("imc", "imc_cmd_start_char", "#") modparam("imc", "outbound_proxy", "sip:sip-test.quintetto.it:15006;transport=tcp") The client start by sending a #join message to kamailio and looking the log file I can see that the room-qsipchat has been create, and also I received the message 200 OK.

Testing dialog module (and acc with dialog cdrs)
by Daniel-Constantin Mierla 18 Oct '22

18 Oct '22

Hello, as I am not a user of dialog variables, I am turning to community to ask for help testing the current master branch with configurations that make use of dialog variables and acc dialog-based cdr generation. With a few reports of issues related to dialog modules and unexpected crashes, I looked over the code and noticed that the access of the value for dialog variables was not protected, making them vulnerable of invalid memory access in case of the variable was updated by another process or dialog was terminated. I introduced a couple of new functions to try to cover different use cases of getting the dlg variable values, dialog management code was not affected, but given that these commits need to be backported to stable branch (5.6), I want to get proper feedback from community that things work fine. A previous attempt of a simpler fix was not enough, having side effects to acc module for dialog-based cdr generation, because it was keeping referenced to many dlg variables at the same time. In short, it would be appreciated any feedback on testing dialog and acc with dialog-based cdr generation using git master branch.

kamailio & rtpengine question

Hi Looking for advise if anyone could point out where im going wrong. My setup is Kamailio Ver 5.6.0 running in azure , rtpengine Version: git-master-dc395d5, behind kamailio I have asterisk ver 18.12.1 Kamailio conf I have interface set as below listen=udp:10.3.1.6:5060 advertise WANIP:5060 and rtpengine.conf set as below interface = eth0/10.3.1.5 but when I can make a call I don't get any audio, rtpengine.log extract below shows that rtp is going to the private IP rather that the Public IP of the phone that initiated the call, do I need to set rtpengine_manage() to fix this?

tsilo usage more generally
by Alex Balashov 14 Oct '22

14 Oct '22

Since on the topic of tsilo: 1. I watched Federico’s presentation on it from 2015, and his examples insinuate that it is necessary to store the index and label of a suspended transaction in some external vehicle, e.g. htable, for use with ts_append_to(). Why would one do this when it is possible to call ts_append() based on R-URI alone? 2. The appropriate pattern of interaction between tsilo and http_async_client — which I imagine to be a rather common use-case — is rather unclear. If I use http_async_query() to call out to a PN service, with $http_req(suspend) = 1, what should happen to the current instance of SIP request processing? That is to say: request_route { . . . t_check_trans(); if(is_method(“REGISTER”)) { . . . save(“location”, “0x06”); if(ts_append(“location”, “$tu”)) { xlog(“success”); } return; } else if(is_method(“INVITE”)) { # PN stuff. ts_store(“$var(uri)”); http_async_query(“http://url”, “PUSH_REPLY”); return; # <— ??? } } route[HTTP_PUSH_REPLY] { . . . if(!t_relay()) sl_reply_error(); } I should add that this proxy front-ends a registrar, but is not in itself a registrar. It contains a shadow registrar - hence the save() calls - in order to be able to take advantage of the ’tsilo’ module, given its dependency on registrar/usrloc. This leads to the difference that the gateway receives requests with RURIs that have already been resolved to a contact binding elsewhere, so there are no lookup() calls. How should this play into the http_async_client workflow?

tsilo logging
by Alex Balashov 13 Oct '22

13 Oct '22

Hi, When there are no stored transactions for an AOR, it logs this error: Oct 13 07:48:18 gw1 /usr/sbin/kamailio[14758]: ERROR: tsilo [ts_append.c:64]: ts_append(): failed to retrieve record for sip:abalashov@sip.evaristesys.com But not having transactions ts_store()’d is a rather normal occurrence, right? It is the expected case the vast majority of the time that someone registers. Does that mean one is simply destined to have this scary-looking error, to the syslog ERROR facility, for a normal runtime condition? Is there not some principle against using attention-grabbing error messages this way? Would a patch to fix be welcome? — Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Re: [SR-Users] play_media sounds interrupted

Sadly my > Kamailio-Fu isn't strong enough to be able to tell you how to run this > sort of timer. :) > > Cheers Thank you for the hint. I was thinking about timers, but rtimer cannot be triggered in an event route. I used a "timer" module, it could trigger another route from the event route but when a new route is triggered unblock_media() is not aware of the call-id and if i assign call-id to a variable in the event route, that variable is unavailable at new route. Hope that make sense. here is my peace of code: loadmodule "timer.so" modparam("timer", "declare_timer", "PB_TIMER=START,5000"); route[START]{ xlog("current call id at event route is $ci, but call-id avp is $avp(call_id)"); unblock_media("all"); timer_enable("PB_TIMER",0); #we need to disable timer or it will be triggered over and over again } event_route[dialog:start]{ xlog("L_INFO", "dialog started, received 200OK"); #block_media(); play_media("all file=/usr/local/src/myfile.wav"); $avp(call_id)=$ci; timer_enable("PB_TIMER",1); }

play_media sounds interrupted
by Stepan Kislyakov 11 Oct '22

11 Oct '22

Hi, I'm using latest kamailio 5.6.2 and rtpengine. I need to play announcement to both parties when call is answered by callee. Now I run play_media in event route but when audio start announcement sounds like we have a 50% packet loss. After it is completed there is no problem with audio both sides. I figured out that if i do block_media() my announcement play perfectly but i dont understand how to do unblock_audio() after announcement ends. Appriciate any help! here is my code: event_route[dialog:start]{ xlog("L_INFO", "dialog started, received 200OK"); block_media(); play_media("all file=/usr/local/src/myfile.mp3"); #unblock_media(); } -- Best Regards Stepan Kislovich

IPSec problem with P-CSCF
by Ali Akbar Hemmati 11 Oct '22

11 Oct '22

Hi everyone, I am using Kamailio as an IMS server. The UE first sends its SIP REGISTER over TCP and gets a 401 in response. Then the UE starts sending its packets over ESP. These ESP packets reach P-CSCF but are not delivered to its process by the kernel. We can see ESP packets in P-CSCF using wireshark. The ports used are correct (both client and server) based on their prior negotiations. We have also checked xfrm policies using the command `ip xfrm policy list` and seems right regarding prior negotiations. Our Linux kernel version is 5.4 and the OS is Ubuntu 20.04. Has anyone any clue of the root cause of this problem? Any ideas are appreciated. Thanks, Aliakbar

kamcli folder
by Volker Denneberg 11 Oct '22

11 Oct '22

hello, I'm not very familiar with PHP, so this may be a stupid question. I'm following https://github.com/kamailio/kamcli to install kamcli. Now i am at $ pip3 install -r requirements/requirements.txt which i should "run inside kamcli folder". So far, I don't have a kamcli folder, so i assume i have to create it. Any recommendations where ? Thanks in advance, Volker

suppress t1 timer retransmissions?
by Brooks Bridges 10 Oct '22

10 Oct '22

So I have a very odd situation that requires me to suppress retransmissions when using t_reply() to send a response back to a UAC that is horribly broken but I'm stuck with for the time being. In the previous iteration of this platform it was fine since I was using a stateless reply, so even though it wasn't "right" it still worked out. I need to replicate this behavior in the event route for http_async_client(), which prevents me from being able to use t_release(). Anyone have any clever ideas? Brooks Bridges 1200 S.

cannot register ACC CDR JSON engine when using acc_json module

Hi everyone, I have some troubles using acc_json module. I can't load it and I don't understand why it fails.

How to use different version of python3 with KEMI
by Lợi Đặng 06 Oct '22

06 Oct '22

Hi all, regarding KEMI with python3, how to specify the python instance we're going to use instead of the system's? i.e: virtual environment or alternative installation of python3. Asking as I'm having existing code running on a version which does not match the system's, and upgrading system's to the specific version is not feasible. I tried specifying the python3 instance in src/modules/app_python3/Makefile but it seems only to help with the build, later the system python is used when kamailio starts. Any help would be appreciated. rgds, Loi Dang Thanh Phone : +84. 774.735.448 Email : loi.dangthanh(a)gmail.com

xhttp - default reply
by Ilie Soltanici 05 Oct '22

05 Oct '22

Hello, Is there a way to set a default reply message for the xhttp module, or at least drop the TCP connection when 'url_match' parameter is used? For example, if used: modparam("xhttp", "url_match", "^/rpc/") which should handle only HTTP requests to this endpoint: http://127.0.0.1:5060/rpc, now if HTTP requests are sent to another endpoint (http://127.0.0.1:5060/v2) - then the TCP connection just stays established even nobody process it. I know I can ignore this parameter and filter all requests in the event_route, but dropping them before calling event_route will make more sense for me, or at least add another parameter to this module that can control that. Thanks

Kamailio Fail to write logs using syslog
by M Arqum CH 02 Oct '22

02 Oct '22

Dear All, Thanks in advance for your help. kamailio installed on debain 9, sometime kamailio failed to generate any log in syslog files i.e messages/ syslog , not even generate a single line against complete dialog or generate partial logs. It's a random behaviour, as i am using syslog with the acc module, kamailio also failed to write acc logs on file which is a very critical matter for me. In a script using xinfo, xnotice, xerr function, no output from these functions in log file. Please suggest a way to fix this issue. modparam("xlog", "log_facility", "LOG_LOCAL1") version: kamailio 5.5.4 (x86_64/linux) 9d039b flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 9d039b -- Regards M Arqum

loose_route() clarification
by Mack Hendricks 30 Sep '22

30 Sep '22

Hey All, I always struggle with loose_route() and I implemented workarounds in the past. But, I want to get a better understanding. I have a SIP Endpoint -> Kamailio -> FreeSWITCH The domain and alias is set to the ip address of the Kamailio server (137.184.130.206) When I get the ACK back from the SIP Endpoint it looks like this ACK sip:18889072085@137.184.72.42:5060;transport=udp SIP/2.0 Via: SIP/2.0/UDP 10.1.10.140:1052 ;branch=z9hG4bK-524287-1---740db0025fa217ce;rport Max-Forwards: 70 *Route: <sip:137.184.130.206;lr>* Contact: <sip:1000@50.192.97.226:53790;transport=UDP> To: <sip:18889072085@dsiptest.dsiprouter.net>;tag=5gv4etZ8tUUcH From: <sip:1000@dsiptest.dsiprouter.net;transport=UDP>;tag=0af5b751 Call-ID: fWido7VIUKIEI6f6kf4vkQ.. CSeq: 1 ACK User-Agent: Z 5.5.8 v2.10.17.2 Content-Length: 0 Kamailio will then remove the ACK and change the RURI to itself, which causes an ACK loop. This is what is look like *ACK sip:137.184.130.206;lr* SIP/2.0 Via: SIP/2.0/UDP 137.184.130.206;branch=z9hG4bK3fd.0cf34b683f0627ee2455594ea6cb2517.0 Via: SIP/2.0/UDP 10.1.10.140:1052 ;received=50.192.97.226;branch=z9hG4bK-524287-1---740db0025fa217ce;rport=1052 Max-Forwards: 69 Contact: <sip:1000@50.192.97.226:1052;transport=UDP> To: <sip:18889072085@dsiptest.dsiprouter.net>;tag=5gv4etZ8tUUcH From: <sip:1000@dsiptest.dsiprouter.net;transport=UDP>;tag=0af5b751 Call-ID: fWido7VIUKIEI6f6kf4vkQ..

We have workarounds for this, but I would prefer to figure out how to have Kamailio handle this natively via the loose_route or tm module. Thanks in advance,

Keepalive dialog with SIP/TLS OPTIONS
by Denys Pozniak 30 Sep '22

30 Sep '22

Hello! In order to keep the SIP/TCP connection alive for some specific clients (more precisely, specific firewalls) in long calls, I use periodic SIP OPTIONS probes through the dialog module. I noticed that when subscribers are using the SIP/TLS protocol, such keepalives are not sent (with SIP/UDP and SIP/TCP working well). I did not detect any obvious errors in the debug mode. Are there any ideas why the messages are not being sent for SIP/TLS leg? ---- loadmodule "dialog.so" modparam("dialog", "db_url", "DBURL") modparam("dialog", "db_mode", 1) modparam("dialog", "ka_timer", 5) modparam("dialog", "ka_interval", 30) modparam("dialog", "ka_failed_limit", 2) modparam("dialog", "send_bye", 1) modparam("dialog", "track_cseq_updates", 1) modparam("dialog", "default_timeout", 7205) ----- dlg_manage(); dlg_set_property("ka-src"); dlg_set_property("ka-dst"); -- BR, Denys Pozniak

Kamailio stops responding to OPTIONS for some time
by Muhammad Danish Moosa 30 Sep '22

30 Sep '22

Hi, With Kamailio 5.5.3 (with KEMI/Lua) I noticed it apparently had stopped responding to OPTIONS in my test system. It can cause problems if a similar issue appears in production. Only thing i could observe it was apparently responding to INVITE and CANCEL etc randomly , its pretty strange as it was not dead completely. There was no core dump, I restarted and it started functioning again. Any clues please? -- Muhammad Danish Moosa " The core of mans' spirit comes from new experiences. "___ Christopher McCandless

http_async_client "route_name" is what type of route?
by Brooks Bridges 30 Sep '22

30 Sep '22

Running into an issue where I can't access certain functions inside the response route or "route_name" for handling the asynchronous reply from an http_async_query() that's being run. Does anyone know what type of route that is considered to be? I know it's not a request route or a failure route based on the errors I'm getting, but I can't find anything that outlines what that route actually is. Thanks! Brooks Bridges 1200 S.
