The index indicates that the sipjson module is not present in 6.0.x.

SIPP UAS scenario
by Sergio Charrua 09 May '25

09 May '25

Hi all! my DEV/LAB environment is comprised of 3 nodes: - SIP 1 with Asterisk and SIPP installed (IP 10.20.0.5) - SIP 2 with Kamailio 5.8 (IP 10.20.0.4) - SIP 3 with Asterisk and SIPP installed (IP 10.20.0.6) Kamailio is set as a stateful SIP Proxy and seems to be working fine (the configuration is pretty standard, using dispatcher to dispatch to destination, even though there is only 1 destination endpoint -» SIP 3) When establishing a call from SIP 1 using Asterisk, the termination is correctly done on SIP 3, also running Asterisk. Hanging up call on SIP 3 will send the correct BYE command to SIP 1 (of course, Kamailio is always between the dialogs) When establishing a call from SIP 1 using SIPP and UAC scenario, the termination is correctly done on SIP 3 also running SIPP with a UAS scenario. However, hanging up the call on SIP 3 (SIPP scenario has a Pause of 2 seconds then sends a BYE message), the BYE command is not forwarded by Kamailio and SIPP keep sending BYE commands. This is an example of the ACK and BYE command being sent from SIP 3: > ACK sip:10.20.0.6:5060;transport=UDP SIP/2.0 > Via: SIP/2.0/UDP > 10.20.0.4;branch=z9hG4bK680a.47d763c3f0732dbe0fdb64ccbeb3454a.0 > Via: SIP/2.0/UDP 10.20.0.5:5060 > ;received=10.20.0.5;branch=z9hG4bK01175d44;rport=5060 > Max-Forwards: 69 > From: "Anonymous" <sip:anonymous@anonymous.invalid>;tag=as023237be > To: <sip:1000@10.20.0.4>;tag=20 > Contact: <sip:anonymous@10.20.0.5:5060> > Call-ID: 568f1bbe197039983fc89cc6403b927b@10.20.0.5:5060 > CSeq: 102 ACK > User-Agent: Asterisk PBX 18.17.1 > Content-Length: 0 and then: > BYE sip:anonymous@10.20.0.5:5060 SIP/2.0 > Via: SIP/2.0/UDP 10.20.0.6:5060 > Route: <sip:10.20.0.4;lr=on;ftage=46906> > Max-Forwards: 70 > From: sipp <sip:sipp@10.20.0.6:5060>;tag=46906SIPpTag0120 > To: : "Anonymous" <sip:anonymous@anonymous.invalid>;tag=as023237be > Call-ID: 568f1bbe197039983fc89cc6403b927b@10.20.0.5:5060 > Cseq: 2 BYE > Contact: sip:sipp@10.20.0.6:5060 > Content-Length: 0 > Subject: Sending BYE I'm pretty sure that the issue is within the SIPP Scenario(s), and my guess goes to the UAS scenario on SIP 3 that has some issue with the BYE command, but I can't figure why the message is wrong! The goal is to have a Testing environment where we can simulate different call situations. SIPP is a wonderful tool but such a PITA !! Probably i am missing some detail somewhere.... Has anyone done such a testing environment? Can anyone share a SIPP UAS scenario where the BYE command is sent from the UAS (send BYE instead of recv BYE) ? SIPP is launched on SIP 1 with: sipp -sf uac.xml -i 10.20.0.5 -p 5060 10.20.0.4 -r 1 -m 1 SIPP is launched on SIP 3 with: sipp -aa -sf uas5.xml -i 10.20.0.6 -p 5060 Thanks in advance. Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Kamailio Crash

Greetings, all, I have a redirect server doing CNAM lookup (via http_async) and STIR/SHAKEN validation with secsipidx that is crashing every few hours. Kamailio 6.0.1 running in a Debian 12 container on an Amazon Linux 2023 host with ARM CPU. root@0689d4fe5fed:/# kamailio -v version: kamailio 6.0.1 (aarch64/linux) fce50d flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT-NOSMP, 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_SEND_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: fce50d compiled on 15:50:40 Apr 1 2025 with gcc 12.2.0 Back trace is here, so I think it's a secsipid related problem?

Having issues with compilation of evapi module and evapi_async_relay functions
by Steve Lim 02 May '25

Hello, We're trying to compile the evapi module. Tested on an upgraded 5.8.6 install as well as a new 6.0.1 install. tm module is loaded (for async), but our issues seem to run deeper. evapi_relay and evapi_async_relay are both not found by the core loader as per load failure (same pattern for evapi_async_relay, ommited for brevity) : 0(21496) DEBUG: <core> [core/sr_module.c:766]: find_mod_export_record(): export of <evapi_relay> not found (flags 1) 0(21496) DEBUG: <core> [core/sr_module.c:766]: find_mod_export_record(): export of <evapi_relay> not found (flags 0) 0(21496) ERROR: <core> [core/cfg.y:3877]: yyparse(): cfg. parser: failed to find command evapi_relay (params 2) 0(21496) CRITICAL: <core> [core/cfg.y:4018]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 111, column 43: unknown command, missing loadmodule? earlier up, we're able to set the bind_addr parameter, so it appears that kamailio does recognize the module (and would fail anyways if it didn't since it's supposed to be loaded) 0(21496) DEBUG: <core> [core/modparam.c:112]: set_mod_param_regex(): 'evapi' matches module 'evapi' 0(21496) DEBUG: <core> [core/sr_module.c:852]: find_param_export(): found <bind_addr> in module evapi [/usr/local/lib64/kamailio/modules/evapi.so] 0(21496) DEBUG: <core> [core/modparam.c:135]: set_mod_param_regex(): found <bind_addr> in module evapi [/usr/local/lib64/kamailio/modules/evapi.so] quick look with nm shows that evapi_relay is exported, but evapi_async_relay isn't. root@kamailio-devel:~# nm -D /usr/local/lib64/kamailio/modules/evapi.so | grep relay 0000000000011dd7 T _evapi_relay 0000000000013b3f T evapi_relay 0000000000013b63 T evapi_relay_multicast 0000000000013b8d T evapi_relay_unicast What am I missing out here?

Kamailio Asterisk Realtime integration
by cedric＠mrtn.ovh 02 May '25

Hello, I'm trying to use Kamailio as proxy for Asterisk. I follow this tutorial https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb I maked some updates to replace old libs and old elements related to db table and fields to use the pjsip table (ps_auths) and fields (username, password). I configured Asterisk Realtime by following the Asterisk documentation (extconfig.conf, sorcery.conf, rec_odbc.conf etc...). I'm lock at this step : The registering is handle correctly by Kamailio and forwarded to Asterisk, but asterisk respond with a "401" error and want to get a digest auth...

WebRTC error NS_ERROR_NET_TIMEOUT
by David Cunningham 01 May '25

01 May '25

Hello, Does anyone know of a reason (besides the obvious like network down) why users might experience a NS_ERROR_NET_TIMEOUT error in their browser when connecting to WebRTC port 8443 on Kamailio (version 5.2.7)? This only happens intermittently, so debugging it is tricky. The number of connections to Kamailio port 8443 peaks at around 4150 daily. The max open files ulimit in Linux is 65535, and in the Kamailio configuration we have "tcp_max_connections=32768" and "tls_max_connections=32000". Would anyone have any suggestions on where the problem might be? Thanks in advance! -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

Looking for Documentation/Guidance to Setup Kamailio and RTPProxy to Terminate Encryption for Asterisk
by Joshua Ruehlig 30 Apr '25

30 Apr '25

Hello, I am fairly new to SIP and just recently setup Asterisk for a few purposes. 1) To have my Hikvision doorbell videocall my phone when someone presses it 2) Videocalling between me and my families' phones/tablets 3) Eventually have a home phone setup for POTS calling. I currently have an ObiHai202 that is still working with GoogleVoice, so this not a priority at the moment. I wanted to have encryption for SIP and RTP outside of my network, but wanted this to all be terminated on my OPNsense router. I can install Kamailio and RTPProxy on OPNsense since they are available for FreeBSD, but it looks like Rtpengine is currently not ported. Ideally I wanted most logic to be handled on my Asterisk server, and have Kamailio/RTPProxy do the bare minimum of encrypting/decryption and rewriting headers as needed. ## Diagram of my Targeted Setup ## * Android Phones / Tablets running Linphone || SIPS(TLS) / SRTP || * OPNsense Router ~ WAN_IP(dynamic)=DOMAIN.com / LAN_IP=10.0.1.1 - Kamailio / RTPProxy || SIP(UDP) / RTP || * FreeBSD Application Server ~ LAN_IP=10.0.1.17 / Internal_IP=192.168.10.17 - Asterisk || SIP(UDP) / RTP || * Hikvision Doorbell ~ Internal_IP=192.168.10.100 #### From my reading so far I have a few questions... * To setup Kamailio > Asterisk it looks like I need to setup the dispatcher module; I also I may need to write some routing code. Am I correct, that I will need to use the dispatcher module? Will I need to modify the routing code/logic or is the default usually sufficient? * I read RTPProxy does support SRTP, but I don't see any configuration options related to encryption. I assume this is just enabled in Asterisk/Kamailio? * For Asterisk configuration I believe I just need to define the outbound_proxy. But now I am not sure how I can require SRTP between my Linphone clients and RTPProxy, while the leg between RTPProxy and Asterisk is unencrypted RTP? Thanks for any help that is provided!

Kamailio TLS Listener Not Binding to Port (5061 or 10061)
by steven.muchwe 29 Apr '25

29 Apr '25

Hello Kamailio Community, I’ve been troubleshooting an issue with Kamailio where the TLS listener fails to bind to any specified ports (5061, 10061, etc.), despite valid configurations and certificates. Here’s a summary of my setup and steps taken: 1. *Environment Details*: - Kamailio version: 5.7.4 - OpenSSL version: 3.0.13 - Operating System: Ubuntu (Noble Release) - TLS module (tls.so) is installed and loaded. 2. *Issue Details*: - Configurations validate successfully (config file ok). - OpenSSL works perfectly when testing certificates and keys with s_server, binding to ports (5061 and others). - Kamailio fails to bind TLS listeners (ss -tulnp shows no activity on the specified ports). 3. *Steps Already Taken*: - Simplified TLS configuration (minimal_tls.cfg) with: plaintext listen=tls:10.14.202.39:5061 loadmodule "tls.so" modparam("tls", "certificate", "/home/localtech/vicissl/868a963bc33d5eae.crt") modparam("tls", "private_key", "/home/localtech/vicissl/private.key") - Tested multiple ports (5061, 10061, 15061). - Checked firewall settings (iptables) and confirmed no restrictions. - Rebuilt Kamailio from source and ensured TLS modules are linked to OpenSSL. - Ran Kamailio with maximum debugging (-ddd) to examine logs—no binding-related errors appeared. 4. *Log Excerpts*: (Attach relevant logs showing TLS initialization or lack of binding activity.) 5. *Question*: What additional steps or configurations should I explore to resolve this issue? Could this be a compatibility problem between Kamailio 5.7.4 and OpenSSL 3.0.13? Any guidance or insights would be greatly appreciated! Best regards, Steven Muchwe Njoroge

Re: SIP Call Drops After 0.32 Seconds – Asterisk on Kubernetes with Kamailio + RTPengine
by airsay＠duck.com 29 Apr '25

29 Apr '25

I will let the more experienced Kamailio folks comment on the technical/Kamailio/RTP modifications that you need to make. The SIP standard requires an ACK to a 200 OK to be sent within that 32 second window. If an ACK is not received, the session is torn down. You would need to do a packet capture to review the Contact header in the SIP and the c: in the SDP. I'm just getting bedded in with SIP, reading Alan B Johnston's "SIP: Understanding the Session Initiation Protocol". Excellent introduction to understanding SIP.
