xcap_client: storage of document in local DB
by Valentin Christoph 05 Oct '20

05 Oct '20

Hi all, Does anybody know, when the xcap_client deletes a registered document from the database? Is it possible to deregister a document? Are you sure, the documented get_elem API function is actually implemented? All the best Christoph

dlg.list_match - Invalid matching key parameter
by Ilie Soltanici 03 Oct '20

03 Oct '20

Hello, The dlg.list_match rpc function from the dialog module is not able to find dialogs matching by the callid key: kamcmd dlg.list_match callid eq "01234567890(a)192.168.0.1" getting back: error: 500 - Invalid matching key parameter I think it's because of this check: 2945:dialog.c: } else if(mkey.len==5 && strncmp(mkey.s, "callid", mkey.len )==0) { the mkey.len - should be 6 in this case, I recompiled locally the dialog module and seems to be working ok. Thank you.

Kamailio 5.2.8 released
by Henning Westerholt 02 Oct '20

02 Oct '20

Hello, Kamailio SIP Server v5.2.8 stable release is out. This is a maintenance release of the old stable branch (5.2), that includes fixes since the release of v5.2.7. There are no change to database schema or configuration language structure that you have to do on previous installations of v5.2.x. Unless major regressions are discovered after the release, this will be the last release of the 5.2 stable branch. The current stable branches 5.3 and 5.4 will continue to be maintained. Deployments running previous v5.2.x versions are strongly recommended to be upgraded to v5.2.8. For more details about version 5.2.8 (including links and guidelines to download the tar file or from GIT repository), visit: https://www.kamailio.org/w/2020/10/kamailio-5-2-8-released/ RPM, Debian/Ubuntu packages will be available soon as well. Many thanks to all contributing and using Kamailio! Cheers, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/>

403 Not relaying (DNS)
by Justin Bookshar 02 Oct '20

02 Oct '20

Hello, I'm trying to use Kamailio as a proxy and registrar component in our network and I would like to be able to do several things. I have an MCU capable of making SIP calls and using Kamailio as a proxy but it is not able to register with Kamailio. I would like to have Kamailio resolve addresses using its DNS component. I have attempted to do this, but I am getting 403 Not relaying responses when attempting to make calls through Kamailio that require the destination URI to be resolved. I have enabled debug and I don't see anything that would cause this. I have verified our /etc/resolv.conf file. When I use the primary DNS server in the list on an endpoint, I can get the address to resolve and the call completes correctly. I know I have working equipment on each end and the DNS server and URI are correct but going through Kamailio fails for both the MCU and endpoint when using it as a proxy. I have also tried to disable the internal resolver by adding the use_dns_cache=no option to the kamailio.cfg file. This produced the same result but as I mentioned I have independently verified the DNS server so I know the issue is isolated to Kamailio. Is it possible for Kamailio to do this or am I wrong in believing it can? The second thing I would like to do is to route calls to the MCU based on a prefix. I think I roughly have this working by adding a custom routing block to the request_route operation. I would also like to be able to make calls to local equipment that is not registered with the registrar and I am not able to do this either. I get the same 403 Not Relaying error when I attempt to call a local endpoint by IP address through the proxy that is also not registered with the registrar. Any info is greatly appreciated. version: kamailio 5.2.5 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, 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_BLACKLIST, HAVE_RESOLV_RES 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: unknown compiled on 09:56:06 Oct 17 2019 with gcc 8.3.0 Thanks, Justin

Kamailio fails to start when tls module parameter 'config' contains a folder name
by Leonid Fainshtein 02 Oct '20

02 Oct '20

Hi, I am using Kamailio 5.4.1 installed from the packages on Ubuntu 18.04. When I define 'modparam("tls", "config", "<folder>")', Kamailio fails to start: ERROR: tls [tls_config.c:418]: tls_load_config(): cannot make tmp file configrcCczj ERROR: <core> [core/sr_module.c:849]: init_mod(): Error while initializing module tls (/usr/lib/x86_64-linux-gnu/kamailio/modules/tls.so) I checked the tls_load_config() function and found that when a folder is defined in the 'config' parameter, the function tries to open a temporary file in the working directory. I believe that the working directory at that point is the folder where Kamailio was started: /usr/sbin. I succeeded to launch Kamailio in two ways: Method 1: copy 'kamailio' to /tmp and modify kamalio.service accordingly. This experiment result made me think that the working folder is the folder where kamailio is started. Method 2: add Kamailio command line parameter "-w /tmp" (I also tried to define the Systemd 'WorkingDirectory' parameter but it didn't have any effect.) I think that the ultimate solution for this problem is to modify the tls_load_config() function in such a way that it will open the temporary file in a folder that is intended for the temporary files. For example, the /tmp folder in Linux and *BSD systems. I guess that /tmp is a good place in MacOS as well. Best regards, Leonid Fainshtein

TOPOS issue
by David Villasmil 01 Oct '20

01 Oct '20

Hello guys, I have this scenario where I have an ongoing transaction. I receive a 180 (non 100rel) with some to_tag, which i forward back to the caller. Then I receive an 183 (100rel) which is forwarded back to the caller, who in turn PRACKs it. It is then that Kamailio (apparently) can't match that transaction internally and replies to the caller (the one PRACKing the 183 (100rel)), with 493 FORBIDDEN. I'm attaching a trace flow. (Kamailio is 10.255.0.1) you need to open the email really wide to see it properly. Anyone ever encountered this? Is this valid and should work? |Time | 10.15.169.4 (FS) 10.255.0.1 (KAM) | (KAM) 1.1.1.10 1.2.3.13 | | | | | | | | | | | | | |0.000000 | INVITE SDP (g722 g71 | | | | |(6000) ------------------> (5060) | | | |0.000941 | 100 Telnyx trying | | | | |(6000) <------------------ (5060) | | | |0.046558 | | | INVITE SDP (g722 g71 | | | | |(33033) ------------------> (5060) | |0.102078 | | | 100 Trying, boss | | | | |(33033) <------------------ (5060) | |0.386867 | | | 180 Ring a ling a li | | | | |(33033) <------------------ (5060) | |0.387578 | 180 Ring a ling a li | | | | |(6000) <------------------ (5060) | | | |3.413368 | | | 181 Prending to forw | | | | |(33033) <------------------ (5060) | |3.414373 | 181 Prending to forw | | | | |(6000) <------------------ (5060) | | | |6.441704 | | | 183 Seeing what I ca | | | | |(33033) <------------------ (5060) | |6.442896 | 183 Seeing what I ca | | | | |(6000) <------------------ (5060) | | | |6.890173 | PRACK | | | | | |(6000) ------------------> (5060) | | | |6.895497 | 403 Forbidden R1 | | | | |(6000) <------------------ (5060) | | | |9.473035 | | | 486 Actually, I'm qu | | | | |(33033) <------------------ (5060) | |9.473561 | | | ACK | | | | | |(33033) ------------------> (5060) | |9.473902 | 486 Actually, I'm qu | | | | |(6000) <------------------ (5060) | | | |9.921200 | ACK | | | | | |(6000) ------------------> (5060) | | | Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337
