[kamailio/kamailio] keep new features in a file in the repository (#668)
by Victor Seva 26 Aug '22

26 Aug '22

This will allow us to point https://www.kamailio.org/wiki/features/new-in-devel to the file and "force" developers to update that file with the new features when they are introduced in the repository Remaining developers to upgrade the wiki seems pointless and anyone can create a PR for changes --- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Diameter AVP handling from kamailio.cfg (#922)
by miricz 11 Jan '22

11 Jan '22

Below feature were discussed with Carsten Bock Currently Diameter AVP values and especially Experimental Result Code is not available from the kamailio.cfg Therefore I would like to request such kind of feature. I would like to use it mainly on Cx interface for Server-Assignment-Answer (SAA), Location-Info-Answer (LIA), Multimedia-Auth-Answer (MAA), Push-Profile-Answer (PPA) It should be implemented such a way like in the ims_charging module. Thank you very much in advance! _Cheers, Zoltan_ -- You are receiving this because you are subscribed to this thread.

[kamailio] add socket activation support (#293)
by zabbal 11 Jan '22

11 Jan '22

Having (optional) support for socket activation in Kamailio would bring several benefits: * Security: systemd can listen on privileged ports or socket paths and start Kamailio with privileges already dropped. * Major upgrades or reconfigurations of Kamailio requiring a full restart are possible without having the listening socket(s) ever go away. * Any service dependent on Kamailio doesn't have to wait for it to finish starting (or start at all). --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/293

[kamailio/kamailio] pv needed to get access to X509v3 Subject Alternative Names of peer's SSL certificate (#707)
by juha-h 11 Jan '22

11 Jan '22

A sip proxy may serve many domains listed in its SSL certificate X509v3 Subject Alternative Name field. In order to find out if a peer sip proxy is serving a particular domain, access would be needed in config file to this list of domains. --- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Expand the list of required default 3rd party libraries for Kamailio (#969)
by Olle E. Johansson 02 Dec '20

02 Dec '20

(from devmeeting #Fosdem) - adding new dependencies as core dependencies - Curl - libssl - uuid - libunistring - libxml2 Any other candidates? They have to be libraries that are commonly installed on most Linux/Unix system. This would mean that a lot of more modules will be built by default, like TLS, HTTP_CLIENT, WEBSOCKET. We may also look over the names of the packages/groups for the build system and linux distros -- You are receiving this because you are subscribed to this thread.

[kamailio] Anyone thinking about adding JWT (JSON Web Token) support to Kamailio (#29)
by mading087 24 Jul '20

24 Jul '20

It seems a good idea to support JWT as a new SIP authorization method. Wonder if anyone is interested? Think auth_db would be the best spot to add support for JWT. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/29

[kamailio/kamailio] cancel the branches instantly instead of on provisional replies (#909)
by aqsyounas 25 Nov '19

25 Nov '19

I am forking a call to multiple destinations and want to keep the only branch which sends quicker provisional 180/183 reply and cancel the remaining branches. Below is my related cfg snippet. modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) modparam("tm", "cancel_b_method", 2) ... route[SIPOUT] { if (uri==myself) return; append_hf("P-hint: outbound\r\n"); append_branch(); append_branch(); route(RELAY); exit; } onreply_route[MANAGE_REPLY] { xdbg("incoming reply\n"); if(status=~"[12][0-9][0-9]") { xlog("L_INFO","Received $rs (IP:$si:$sp)\n"); if(status=~"18[03]"){ t_cancel_branches("others"); xlog("L_INFO","cancelled all other branches\n"); } route(NATMANAGE); } } ... But I see kamailio does not instantly send CANCEL to other branches after it has received 180/180 from any branch. Kamailio is sending CANCEL to other branches after they start sending 180/183 one by one. I want to cancel other brances instantly as soon as i get reply from any other branch. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Unexpected log_systemd behavior when daemon is forked (#799)
by Anthony Messina 22 Nov '19

22 Nov '19

Starting Kamailio (4.4 with branch updates through e43d82d applied) with the following systemd unit file, native systemd/journald logging doesn't work as expected. I *do* get core logging when I use ``` log_engine_type="systemd" loadmodule "log_systemd.so" ``` but `xlog` and `sd_journal_print` *don't* send anything to the journal. When I comment out `log_engine_type`, keeping the log_systemd.so module loaded, `sd_journal_print` *does* log the messages properly to the systemd journal, `xlog` and core startup messages are sent to syslog. If I change the service to `Type=simple` and add the `-D` option to `ExecStart` to disable forking, then logging to systemd via `xlog` and `sd_journal_print` works, but TCP/TLS listeners aren't created. ``` [Unit] Description=Kamailio SIP Server Documentation=man:kamailio(8) http://www.kamailio.org/ After=syslog.target network-online.target Wants=network-online.target [Service] Type=forking User=kamailio Environment=SHM_SIZE=64 Environment=PKG_SIZE=8 ExecStartPre=/usr/sbin/kamailio -c ExecStart=/usr/sbin/kamailio -m $SHM_SIZE -M $PKG_SIZE -P /run/kamailio/kamailio.pid PIDFile=/run/kamailio/kamailio.pid Restart=on-failure RestartSec=30 RuntimeDirectory=kamailio RuntimeDirectoryMode=0750 [Install] WantedBy=multi-user.target ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Incorrect translation of tel: uri to sip: uri in tel2sip() (#1173)
by Donald Carr 15 Nov '19

15 Nov '19

### Description  I received a wireshark trace from a team member showing that a tel: uri was translated to a sip: uri in a very strange (invalid) way: INVITE tel:491234567891;phone-context=ims.mnc001.mcc001.3gppnetwork.org Was translated to: INVITE sip:491234567891;phone-context=ims.mnc001.mcc001.3gppnetwork.org@ims.mnc001.mcc001.3gppnetwork.org;user=phone ### Troubleshooting I first thought this was definitely an error, and only the phone number should be copied to the sip: uri. But, on further reading of the specification, (https://www.ietf.org/rfc/rfc3261.txt), I see that it is in fact legal to leave all parameters in. Though, when the phone-context parameter is simply a domain, it would at least seem the cleanest thing would be to remove it when the exact same domain is also inserted after the @ in the sip message. So, looking to find where the message is translated, I saw in the scscf.cfg configuration file that there is a translation specified. I found that "tel2sip" is mapped to the C function of the same name tel2sip() In this function, the translation will do exactly what I found in the trace, in other words, it will leave in all parameters separated by semi-colon, inserted before the @ symbol. But, reading the spec, I see that the spec is not being followed in any case. The spec states that all parameters included when translating, must be switched to alphabetic order, with the exception that isdn-subaddress and post-dial, must occur first and in that order. There is no code in tel2sip() to perform that sorting. Also, the parser removes '(', ')', '.', and '-' in the phone number, as specified, but, these same characters could be scattered anywhere in invalid places, and they are just silently removed, '+' can scattered anywhere and it is just left alone, Other characters can be scattered anywhere and they will just be left as-is, no error. So, I feel there should be some minimal checking of the phone number, trying to follow the spec (if we could just execute the BNF from the spec!). #### Reproduction  This can be reproduced by sending a tel: uri with parameters inserted separated by semicolon. #### Debugging Data  ``` (none) ``` #### Log Messages  ``` (none) ``` #### SIP Traffic  ``` See attached file ``` ### Possible Solutions  The solution would be to modify tel2sip(), adding the sorting of parameters, putting the two exceptions first if they exist, before inserting back into the string. We should also throw errors on obvious bad formatting and ilegal characters, etc, in the input tel: uri Should we remove the "phone-context" if it is a domain and also exactly the same as the domain inserted after the @? ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.0.0-dev5 (x86_64/linux) da4ef4-dirty 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_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: da4ef4 -dirty compiled on 10:37:40 May 12 2017 with gcc 5.4.0 ``` SIP spec: https://www.ietf.org/rfc/rfc3261.txtWireshark output: ![wireshark-tel2sip](https://user-images.githubusercontent.com/4886876/27705203-cfd3c150-5cd2-11e7-9f77-1664a51e7ac3.png) ``` In RFC 3966, Tel URI format: The "tel" URI has the following syntax: telephone-uri = "tel:" telephone-subscriber telephone-subscriber = global-number / local-number global-number = global-number-digits *par local-number = local-number-digits *par context *par par = parameter / extension / isdn-subaddress isdn-subaddress = ";isub=" 1*uric extension = ";ext=" 1*phonedigit context = ";phone-context=" descriptor descriptor = domainname / global-number-digits global-number-digits = "+" *phonedigit DIGIT *phonedigit local-number-digits = *phonedigit-hex (HEXDIG / "*" / "#")*phonedigit-hex domainname = *( domainlabel "." ) toplabel [ "." ] domainlabel = alphanum / alphanum *( alphanum / "-" ) alphanum toplabel = ALPHA / ALPHA *( alphanum / "-" ) alphanum parameter = ";" pname ["=" pvalue ] pname = 1*( alphanum / "-" ) pvalue = 1*paramchar paramchar = param-unreserved / unreserved / pct-encoded unreserved = alphanum / mark mark = "-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")" pct-encoded = "%" HEXDIG HEXDIG param-unreserved = "[" / "]" / "/" / ":" / "&" / "+" / "$" phonedigit = DIGIT / [ visual-separator ] phonedigit-hex = HEXDIG / "*" / "#" / [ visual-separator ] visual-separator = "-" / "." / "(" / ")" alphanum = ALPHA / DIGIT reserved = ";" / "/" / "?" / ":" / "@" / "&" / "=" / "+" / "$" / "," uric = reserved / unreserved / pct-encoded ``` * **Operating System**:  ``` # uname -a Linux epc-enablers 4.4.0-51-generic #72-Ubuntu SMP Thu Nov 24 18:29:54 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
