[kamailio/kamailio] lost: resolve geolocation url using POST (#2641)
by sergey-safarov 03 May '21

03 May '21

### Description According [RFC5985](https://tools.ietf.org/html/rfc5985) > The POST method is the only method REQUIRED for HELD. If a LIS chooses to support GET or HEAD, it SHOULD consider the kind of application doing the GET. So not all LIS servers support the GET method and only the POST method always present. Also [rfc6753#section-3.2](https://tools.ietf.org/html/rfc6753#section-3.2) > An HTTP GET request to a HELD URI produces a HELD response as if the following HELD request had been sent using HTTP POST: <locationRequest xmlns="urn:ietf:params:xml:ns:geopriv:held"> <locationType exact="false"> geodetic civic </locationType> </locationRequest> ### Expected behavior Dereference Geolocation URLs using POST method with content according [rfc6753#section-3.2](https://tools.ietf.org/html/rfc6753#section-3.2) -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [Feature] RFC 8898 support (#2669)
by Grzegorz Kapkowski 03 May '21

03 May '21

### Description Hi, is there anyone working on adding support for [RFC 8898](https://tools.ietf.org/html/rfc8898) and do you know of any clients that already implement it or are working towards supporting it? How could I go about starting such effort? ### RFC 8898 Third-Party Token-Based Authentication and Authorization for Session Initiation Protocol (SIP) Abstract This document defines the "Bearer" authentication scheme for the Session Initiation Protocol (SIP) and a mechanism by which user authentication and SIP registration authorization is delegated to a third party, using the OAuth 2.0 framework and OpenID Connect Core 1.0. This document updates RFC 3261 to provide guidance on how a SIP User Agent Client (UAC) responds to a SIP 401/407 response that contains multiple WWW-Authenticate/Proxy-Authenticate header fields. ... -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] DNS destination resolution failure when too many SRV records (#2651)
by jklingenmeyer 03 May '21

03 May '21

### Description DNS core resolver fails in returning a valid IP when there are too many SRV results in the DNS reply. It acts like if no records were found, so request is not relayed and a 478 reply is generated instead (in the example of a DNS name in $ru or $du). ### Troubleshooting #### Reproduction It is easy to reproduce with DNS failover + NAPTR enabled (cf parameters used far below) and with such DNS records: ``` # dig +short NAPTR ko.sip.provider.com 50 30 "S" "SIP+D2U" "" _sip._udp.ko.sip.provider.com. # dig +short SRV _sip._udp.ko.sip.provider.com. 10 10 5060 endpoint-01.k0.sip.provider.com. 10 10 5060 endpoint-02.k0.sip.provider.com. 10 10 5060 endpoint-03.k0.sip.provider.com. 10 10 5060 endpoint-04.k0.sip.provider.com. 10 10 5060 endpoint-05.k0.sip.provider.com. 10 10 5060 endpoint-06.k0.sip.provider.com. 10 10 5060 endpoint-07.k0.sip.provider.com. 10 10 5060 endpoint-08.k0.sip.provider.com. 10 10 5060 endpoint-09.k0.sip.provider.com. # Each SRV result above has a corresponding # 'A' record so that command below gives a correct IP: # dig +short A endpoint-01.k0.sip.provider.com. ``` To reproduce, relay a request towards it, like: `$du="sip:ko.sip.provider.com"` #### Debugging data One interesting thing is that Kamailio behaves exactly the same as the `sip-dig` tool. But `sip-dig` seems to be limited on the DNS reply size it can handle (cf my comment below about the RFC). Does Kamailio have this same kind of limitation regarding DNS resolution? #### Log Messages ##### Failure example: with 9 SRV records ``` DEBUG: <core> [core/dns_cache.c:527]: _dns_hash_find():

There are some max defined in `dns_cache.c` but I did not found a relation between them and my issue. Could there be a limitation in result size? Here is what I got from my RFCs reading regarding that: * Extract from **RFC 2782 DNS RR** (mentioned in RFC 3263 as being the RFC to follow for implementing DNS in SIP): > Currently there's a practical limit of 512 bytes for DNS replies. > Until all resolvers can handle larger responses, domain administrators are strongly advised to keep their SRV replies below 512 bytes. There is a RFC about how to deal with truncated messages: > If a truncated response comes back from an SRV query, the rules described in RFC 2181 (https://tools.ietf.org/html/rfc2181#page-11) shall apply. ### Additional Information * **Kamailio Version** - kamailio 5.3.8 ``` dns_try_naptr=yes dns_tcp_pref = 1 dns_udp_pref = 1 dns_tls_pref = 1 dns_srv_lb=yes use_dns_failover=yes use_dns_cache=yes dns_cache_max_ttl=30 ``` * **Operating System**: Debian 9.13 on Docker Thanks -- 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.

In the case of LOST, a redirect response is evaluated. In case a lost_held_request (used to connect to a LIS via POST or GET) is passed with an empty string ("") for the connection parameter, then P-A-I or From header value hostnames are used for NAPTR lookup to get a corresponding service. http_client: http_client_request (api) content-type header support - new api call including a content-type argument implemented as new function - required to resolve geolocation url using POST (#2641) - Note: not sure if this is the most elegant solution, but it helps to avoid backward compatibility issues You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/2675 -- Commit Summary -- * http_client: http_client_request (api) content-type header support * lost: new features, attributes and a new function to dereference location -- File Changes -- M src/modules/http_client/curl_api.c (1) M src/modules/http_client/curl_api.h (3) M src/modules/http_client/functions.c (68) M src/modules/http_client/functions.h (14) M src/modules/lost/functions.c (902) M src/modules/lost/functions.h (3) M src/modules/lost/lost.c (88) A src/modules/lost/naptr.c (255) A src/modules/lost/naptr.h (38) M src/modules/lost/pidf.c (5) A src/modules/lost/response.c (991) A src/modules/lost/response.h (131) M src/modules/lost/utilities.c (447) M src/modules/lost/utilities.h (27) -- Patch Links -- https://github.com/kamailio/kamailio/pull/2675.patch https://github.com/kamailio/kamailio/pull/2675.diff -- You are receiving this because you are subscribed to this thread.

xflag losing state on serial forking
by David Escartin 09 Apr '21

09 Apr '21

Dear all i think i have noticed a wrong behaviour with xflags. When they are set in a failure_route and a t_relay is done after that to a destination, its state is lost in the next on_reply route. This doesn't happen with regular transaction flags, and it doesn't happen with xflags either when xflag is set inside an onreply_route. We have seen it on versions 5.3 and 5.4 Could you please confirm this? thanks a lot regards david escartin -- [image: Logo] David Escartín Almudévar VoIP/Switch Engineer descartin(a)sonoc.io *SONOC* C/ Josefa Amar y Borbón, 10, 4ª · 50001 Zaragoza, España Tlf: +34 917019888 · www.sonoc.io

[kamailio/kamailio] Add display name support to "pua_dialoginfo" (#2615)
by Jake Greene 05 Apr '21

05 Apr '21

### Description It doesn't look like the "pua_dialoginfo" module has support for the "display" attribute in the identity tag. This tag is used by some phones to update the phone display with caller/callee information for the respective key. I'm wondering how difficult it would be to add this feature. Thanks in advance for anyone who reads this! ### Expected behavior Kamailio includes display attribute in identity tags in generated publish messages. <pre> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full"> <dialog id="as7d900as8" call-id="a84b4c76e66710" local-tag="1928301774" remote-tag="456887766" direction="initiator"> <state>early</state> <local> <identity display="Alice">sip:alice@example.com</identity> <target uri="sip:alice@phone11.example.com"/> </local> <remote> <identity display="Bob">sip:bob@example.org</identity> <target uri="sip:bobster@phone21.example.org"/> </remote> </dialog> </dialog-info> </pre> #### Actual observed behavior Kamailio generates a publish request for dialog events similar to the one below. The display attribute is not included in the "identity" tags. This means that when a notify message is sent to a watcher for this publish, the name is not rendered on the phone display. <pre> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full"> <dialog id="as7d900as8" call-id="a84b4c76e66710" local-tag="1928301774" remote-tag="456887766" direction="initiator"> <state>early</state> <local> <identity>sip:alice@example.com</identity> <target uri="sip:alice@phone11.example.com"/> </local> <remote> <identity>sip:bob@example.org</identity> <target uri="sip:bobster@phone21.example.org"/> </remote> </dialog> </dialog-info> </pre> ### Possible Solutions I added a small modification to the module as a POC and it works as expected. With the following modification, the phone display is updated with the string in the “display” attribute. I added line 191-193 below, between lines 190 & 191 on the current master branch. The example below shows the “remote” tag, I also did the same thing for the local tag a few more lines down. <pre> 184 tag_node = xmlNewChild(remote_node, NULL, BAD_CAST "identity", 185 BAD_CAST buf) ; 186 if( tag_node ==NULL) 187 { 188 LM_ERR("while adding childn"); 189 goto error; 190 } 191 /* Testing - adding display attribute to the identity tag */ 192 xmlNewProp(tag_node, BAD_CAST "display", BAD_CAST "RemoteCallerName"); 193 /* */ 195 196 tag_node = xmlNewChild(remote_node, NULL, BAD_CAST "target", NULL); 197 if( tag_node ==NULL) </pre> Here is a link to the file in the module I’m referring to: https://github.com/kamailio/kamailio/blob/master/src/modules/pua_dialoginfo… I don’t really have any professional experience writing C code, and I was unable to identify a way to grab this string from the “From” header. Unfortunately, because I would have really loved to give this feature back to the community! ### Additional Information Thank you so much for this amazing software. I absolutely adore Kamailio! If someone is interested in this, please let me know if there is anything I can do to help. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] siptrace: duplicate_uri with multiple values (#2693)
by sergey-safarov 02 Apr '21

02 Apr '21

### Description As admin, I want check TLS encrypted call signaling on local Kamailio. To do this I can use [this instruction](https://voipembedded.wordpress.com/2021/03/22/troubleshooting-…. Here used `siptrace` module. But at the same time, I need to send the same call signaling to the company `Homer` server. So I need to send a copy of the call signaling in two directions. Could you add the ability to allow specify multiple values in `duplicate_uri` param like. ``` modparam("siptrace", "duplicate_uri", "<sip:127.0.0.1:9060>,<sip:homer.example.com:9060>") ``` -- You are receiving this because you are subscribed to this thread.
