[kamailio/kamailio] Feature request: Increase number of "custom fields" in sipcapture-module (#1278)
by mihovilkolaric 11 Jan '22

11 Jan '22

The module sipcapture provides the modparams "custom_field1_header" to "custom_field3_header", to store the content of up to three arbitrary header fields as separate columns in the database. They can be used as all other "standard" columns in homer. However I found out that searching/filtering for even more (standardized, as well as private) header fields would be very helpful (I identified about ten interesting additional headers, but the number is constantly increasing ;-) ). Could you thus please increase the number of custom fields? (I suppose the most flexible solution could be something as the db_extra in the acc-module, which is not fixed to certain columns (regarding number of columns, as well as their names) (see https://www.kamailio.org/docs/modules/5.0.x/modules/acc.html#acc.p.db_extra ).) -- 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] TLS module: access UID attribute (#1843)
by Sebastian Denz 24 Nov '21

24 Nov '21

### Description While implementing an edgeproxy based on kamailio i have to add a custom SIPHeader which contains the uid from the useragents client certificate. The UID is part of the subject like: O = Company CN = Sebastian Denz UID = denz But i cant access that attribute. All i can do is reading the CN and O. ### Expected behavior There should be a select to access the uid Attribute from the subject, or at least a select which returns the whole subject, so it can be parsed manually in kamailio.cfg. #### Actual observed behavior It is only possible to access the O and CN field from the subject. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` kamailio -v version: kamailio 5.2.0 (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 with gcc 5.3.1 ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] topos module producing invalid SIP message (missing Via header) when handling 200 OK to OPTIONS request (#1350)
by George Diamantopoulos 20 Oct '21

20 Oct '21

Hello all, I've come across the following issue with topos on Kamailio 5.1.0-rc2. ### Description Kamailio acts as a proxy for asterisk instances residing in a private IP range. Asterisk's peers are configured with their public IP address or hostname, but asterisk will dispatch requests to them to kamailio instead (because kamailio's IP is set in outboundproxy option in peer definition). This works fine for INVITEs, but if qualify=yes is set for the peer, asterisk will send out OPTIONs to monitor these peers. If the topos module is loaded, 200 OK replies to these OPTIONs will be malformed when forwarded from kamailio to asterisk (no Via header present). Disabling the topos module will resolve this. ### Troubleshooting #### Reproduction Configure a peer in asterisk with outboundproxy option set to kamailio's IP address. Set qualify=yes. Adjust kamailio's default configuration so that OPTIONs to other hosts besides itself are routed. Change the following section in request_route: ``` if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } ``` to: ``` if ( ($rU==$null) && !(is_method("OPTIONS")) ) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } # Permit asterisk's monitoring using options if(is_method("OPTIONS") && uri!=myself) { route(RELAY); } ``` Enable and configure the topos module with database. #### SIP Traffic asterisk:5060 -> kamailio:5060 ``` OPTIONS sip:peer.domain.tld SIP/2.0 Via: SIP/2.0/UDP asterisk:5060;branch=z9hG4bK460330cf;rport Max-Forwards: 70 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld> Contact: <sip:asterisk@asterisk:5060> Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS User-Agent: myUA Date: Sun, 03 Dec 2017 00:39:38 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 ``` kamailio:5060 -> peer:5060 ``` OPTIONS sip:peer.domain.tld SIP/2.0 Via: SIP/2.0/UDP kamailio:5060;branch=z9hG4bK460330cf;rport Max-Forwards: 69 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld> Contact: <sip:asterisk@asterisk:5060> Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS User-Agent: myUA Date: Sun, 03 Dec 2017 00:39:38 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 ``` peer:5060 -> kamailio:5060 ``` SIP/2.0 200 OK Via: SIP/2.0/UDP kamailio;branch=z9hG4bKda8d.cc03bd2def8ad36e8c43f61ab31a636f.0;received=kamailio;rport=5060 From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld>;tag=as472874ee Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS Server: myUA Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Contact: <sip:peer:5060> Accept: application/sdp Content-Length: 0 ``` **kamailio:5060 -> asterisk:5060: Missing Via Header** ``` SIP/2.0 200 OK From: "asterisk" <sip:asterisk@domain.tld>;tag=as690c2406 To: <sip:peer.domain.tld>;tag=as472874ee Call-ID: 6548f43b2d8740122186bb0c6e72ac78(a)domain.tld CSeq: 102 OPTIONS Server: myUA Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Contact: <sip:peer:5060> Accept: application/sdp Content-Length: 0 ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.1.0-rc2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, 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: unknown compiled with gcc 6.3.0 ``` * **Operating System**: ``` Debian 9.1 ``` * **Other pertinent configuration information**: This kamailio box has several network interfaces. mhomed is not used, instead force_send_socket is called where necessary.

[kamailio/kamailio] db_redis: add support for native redis cluster (#1997)
by George Diamantopoulos 15 Sep '21

15 Sep '21

The db_redis module seems to only support connecting with a single redis instance. It is not evident from the documentation if it implements support for native redis cluster by honouring 'MOVED' replies. ndb_redis seems to have support for native redis clusters, and supports both automatic (see allow_dynamic_nodes parameter of ndb_redis) and manual configuration of redis nodes. Since both modules are based on the hiredis library, is it safe to assume this support could be easily implemented, with some code sharing between the two modules perhaps? If db_redis supports clusters with automatic configuration only (by processing MOVED replies), perhaps the module's documentation should be updated to reflect that. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Wrong Record-Route and Via header fields when TCP is used (#2033)
by leonid-xorcom 03 May '21

03 May '21

### Description Kamailio server has two legs that are connected to different networks. I'm using Kamailio v.5.2.3 and the "enable_double_rr" is implicitly set to "1". The leg "A" IP address is 10.28.80.1 The leg "B" IP address is 192.168.9.103 The call is initiated from 10.28.80.47 According to the "rr" module documentation, function record_route() should insert two "Record_Route" header fields when a request is accepted on one leg is should go out via the second leg. This works as expected in case of UDP protocol: INVITE sip:2601@192.168.0.178:49162;transport=udp SIP/2.0 Record-Route: <sip:192.168.9.103;r2=on;lr;did=e2c.a191> Record-Route: <sip:10.28.80.1;r2=on;lr;did=e2c.a191> Via: SIP/2.0/UDP 192.168.9.103;branch=z9hG4bKcfa5.d64ecbd87d5315b5993c4ccf16f86537.0 Via: SIP/2.0/UDP 10.28.80.47:5060;rport=5060;branch=z9hG4bK3a9e9a4d But when the TCP protocol is used AND "listen" parameters are defined: listen=udp:10.28.80.1:5060 listen=tcp:10.28.80.1:5060 listen=udp:192.168.9.103:5060 listen=tcp:192.168.9.103:5060 then the outbound message looks like this: INVITE sip:2601@192.168.0.178:48758;transport=tcp SIP/2.0 Record-Route: <sip:10.28.80.1;transport=tcp;lr;did=bcd.72f> Via: SIP/2.0/TCP 10.28.80.1;branch=z9hG4bKb9ca.26ea08654c9dbc32bb0dc6e3b6f92d45.0;i=3 Via: SIP/2.0/TCP 10.28.80.47:5060;rport=33976;branch=z9hG4bK5291fab1 There are two problems there: a) only one Record-Route with leg "A" is inserted b) the added "Via" header field contains the leg "A" IP address instead of expected leg "B" IP address (192.168.9.103). In the LAN trace, I see that in reality the message was sent from leg "B". IMPORTANT: The problem occurs only when the "listen" parameters are defined in the Kamailio configuration. When the "listens" are not configured then everything works correctly. ### Troubleshooting #### Reproduction #### Debugging Data #### Log Messages http://updates.xorcom.com/~xorcom/kam-tcp-problem.tar.gz The archive contains the following files: * syslog-bad.log and bad.cap - Kamailio log and tcpdump trace of a call when the problem occurs * syslog-good.log and good.cap - Kamailio log and tcpdump trace of a call when the problem doesn't occur #### SIP Traffic ### Possible Solutions ### Additional Information kamailio -v version: kamailio 5.2.3 (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 with gcc 7.3.0 ***Operating System**: Ubuntu 18.0.4 -- 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/kamailio] topos module seems to break re-SUBSCRIBE routing to downstream destinations (#1724)
by George Diamantopoulos 18 Nov '20

18 Nov '20

### Description Kamailio seems to fail to properly route in-dialog SUBSCRIBE with the topos module enabled. In this configuration, SUBSCRIBEs are expected to be delivered to a downstream UAS, an asterisk instance in the internal network. record_route() is executed for all initial requests, including SUBSCRIBEs. Routing is performed correctly with the topos module disabled, no other modifications were needed.  ### Troubleshooting I haven't been able to work around this issue in any other way other than disabling the topos module. #### Reproduction The configuration used is a heavily modified version of the example configuration file, but the handling of SUBSCRIBEs is generally simple. The initial SUBSCRIBE is subject to some tests, the R-URI is edited and dispatched to a farm of asterisk servers based on some criteria. Record Routing is enforced, so subsequent in-dialog re-SUBSCRIBEs are expected to be routed with loose_route(), which doesn't seem to handle things properly.  #### Debugging Data I'm attaching kamailio logs with debug=4, cfg_trace  #### Log Messages See attachments  #### SIP Traffic Please see: https://www.cloudshark.org/captures/d2643aae7f2a  ### Possible Solutions Using topoh instead for topos, but unfortunately this will break communication for other reasons (messages too large/UDP fragmentation for some peers). ### Additional Information * **Kamailio Version** Tried with kamailio 5.1.6 and kamailio 5.3.0-dev0 deb.kamailio.org repositories were used to acquire binaries for both versions * **Operating System**: Debian Stretch  [resubscribe.log](https://github.com/kamailio/kamailio/files/2586440/resubsc… -- You are receiving this because you are subscribed to this thread.
