We are fixing the FreeSwitch issue with Contact headers containing ";" character in the user param. https://github.com/signalwire/freeswitch/issues/2824 Now required to test other use cases where the user part contains "&" / "$" / "," / "?" / "/" Could you provide some examples of SIP messages with these characters in the user part?

Dispatcher sets IP flag on servers even though SIP OPTIONS receive 200 OK
by Pablo Oliver 26 Jun '25

26 Jun '25

Hi there, I'm new to Kamailio, and maybe this is a silly question. I’ve set up Kamailio as a SIP proxy with two Asterisk servers acting as media services. This is my configuration for the dispatcher module: loadmodule "dispatcher.so" modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "flags", 2) modparam("dispatcher", "ds_ping_interval", 20) modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_probing_threshold", 5) modparam("dispatcher", "ds_inactive_threshold", 5) modparam("dispatcher", "ds_ping_latency_stats", 1) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=403;code=488;class=3") modparam("dispatcher", "ds_ping_from", SIPCALL) I can see the SIP OPTIONS requests going from Kamailio to Asterisk and receiving 200 OK responses. However, the dispatcher is still setting the IP (Inactive Probing) flag on the servers: kamcmd dispatcher.list { NRSETS: 1 RECORDS: { SET: { ID: 1 TARGETS: { DEST: { URI: sip:172.16.254.21:5060 FLAGS: IP PRIORITY: 0 LATENCY: { AVG: 0 STD: 0 EST: 0 MAX: 0 TIMEOUT: 183 } } DEST: { URI: sip:172.16.254.20:5060 FLAGS: IP PRIORITY: 0 LATENCY: { AVG: 0 STD: 0 EST: 0 MAX: 0 TIMEOUT: 183 } } } } } } So when I try to use ds_select_dst("1", "4"), it always fails. Did I miss something in my configuration? Thanks! Regards, Pablo.

Context of t_continue
by johannes.westhuis＠auerswald.de 25 Jun '25

25 Jun '25

Hi, we are using kamailio 5.8 with t_suspend to suspend calls until a push notification wakes up the phone. The phone will then send an NOTIFY with information, so that t_continue can be called. This works well, but currently we are facing issues with rtpengine, and looking at the logs, there is something suspicious: we are calling: t_continue("$sht(vtp=>id_index::$hdr(X-Resume))", "$sht(vtp=>id_label::$hdr(X-Resume))", "RESUME"); ... route[RESUME] { xdbgl("[RESUME] rm=$rm ru=$ru du=$du \n"); ... after the call to t_continue i can see the log mentioned above: Jun 24 16:20:52 proxy5 /usr/sbin/kamailio[2337]: DEBUG: {1 34558 NOTIFY sFsXwoWeDXHOzRHqVfA4E5KDT9U6qoov} <script>: 486:[RESUME] rm=INVITE ru=sip:<URI_REDACTED> I wondered why the log call still logs the context as the NOTIFY context and not the INVITE context, and if that might lead to issues? currently we get problems with rtpengine_manage when we try to call it in the route[RESUME] Jun 24 16:20:52 proxy5 /usr/sbin/kamailio[2337]: DEBUG: {1 34558 NOTIFY sFsXwoWeDXHOzRHqVfA4E5KDT9U6qoov} rtpengine [rtpengine.c:3198]: rtpp_function_call(): proxy reply: d7:warning38:Call-ID not found or tags didn't match6:result2:oke We are currently checking, if we can work around this issue, but i am hoping to getting a bit of insight from you. Best Regards JWes

multihoming & BYEs
by Dustin Marquess 25 Jun '25

25 Jun '25

All, I've tried searching and have found similar posts before, but I have yet to find a real 'solution'. I'm running Kamailio 6.0.1 & RTPEngine 13.3.1.7 (on a Linux VM) as a "SBC" (at home) using the config from: https://github.com/voiceboys/sbcOS/blob/version_2.0/var/www/html/alpine/con… Except that I've added the following: mhomed=1 modparam("rr", "force_send_socket", 1) The SBC is dual-homed: one interface on the local LAN and another interface directly on the Internet/WAN (real public IP). Everything works fine, EXCEPT if the remote end (the side on the WAN/Internet) hangs up first. If they do, the BYE never makes it past Kamailio to the local PBX and/or phone. https://users.openser.narkive.com/1aK7n8Il/sr-multihomed-kamailio-and-enabl… suggests to use $sht to save the information needed, but I have no clue where in the config to put that. Any help would be greatly appreciated. Thanks! -Dustin

All your questions have been checked and ruled out. However, I still not able to resolve it. Hence, I decided to approach it differently with manual loadparam loadmodule "tls.so" #modparam("tls", "config", "/etc/kamailio/tls/tls.cfg") modparam("tls", "tls_method", "TLSv1.2+") # Force TLS 1.2+ for all connections modparam("tls","require_certificate",1) modparam("tls","verify_certificate",1) modparam("tls","verify_depth",9) modparam("tls","certificate","/etc/kamailio/tls/certificate.pem") modparam("tls","private_key","/etc/kamailio/tls/private_key.pem") modparam("tls","ca_list","/etc/kamailio/tls/server_cas.pem") Now it is showing that the TLS connectivity exist, but I know can't let the Kamailio docker run properly and I keep receiving this log message 0(1) DEBUG: <core> [core/tcp_main.c:1305]: find_listening_sock_info(): binding to source address 192.168.254.19:5061 failed: [Address in ue] [98] 0(1) DEBUG: tls [tls_server.c:242]: tls_complete_init(): completing tls connection initialization 0(1) DEBUG: tls [tls_server.c:204]: tls_get_connect_server_name(): xavp with outbound server name not found 0(1) DEBUG: tls [tls_server.c:178]: tls_get_connect_server_id(): xavp with outbound server id not found 0(1) DEBUG: tls [tls_server.c:185]: tls_get_connect_server_id(): outbound server id not set Just to confirm, does it mean that I cant be using the TLS listen port and output port the same?

(0600 with owner kamailio or 644 with owner root etc) - Correctly named path and cert name as well in the above file? Hope this helps. John.
