Dialog timer reset on UPDATE
by Alex Balashov 08 Aug '24

08 Aug '24

Hi, I have a dialog where I have set: dlg_set_property("timeout-noreset"); But it seems the timeout is reset anyway when handling an in-dialog UPDATE request, at least, on Kamailio 5.5.4. This does not seem to happen with reinvites. I haven't been able to get more information thus far, other than to be able to say that there is nothing unusual about the UPDATE request and there are no additional errors at log level 2. I was wondering if anyone else has encountered this. -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

app_python3 method not found or is not callable
by Westhuis, Johannes 08 Aug '24

08 Aug '24

Hi, we are using kamailio with app_python3. It works very good, but in some cases, there are error logs stating: app_python3 [python_exec.c:91]: apy_exec(): <python method> not found or is not callable It happens sporadically, and a restart of kamailio fixes it. As far as i can see it might be linked to concurrent arrival of several messages. Best regards, Johannes # kamailio -v version: kamailio 5.5.6 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED 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: compiled on 12:01:03 Jul 22 2024 with gcc 10.2.1

http_async_query on carrierfailureroute changes rd back to carrieroute primary
by Maharaja Azhagiah 07 Aug '24

07 Aug '24

Hi I am running kamailio 5.4 on debian I have carrierfailureroute configured incase of primary service provider fails. I also have Stirshaken configured to add Identity header on outbound calls. Issue is when call fail overs to carrierfailureroute, http_async_query changes $ru to the primary carrier From the debug logs, when primary carrier sends a 488 (primary carrier expects SIP TLS but my call is UDP - to test the failover scenario) 39(285) DEBUG: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} tmx [t_var.c:561]: pv_get_tm_reply_code(): reply code is <488> 39(285) DEBUG: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} carrierroute [cr_func.c:178]: set_next_domain_on_rule(): searching for matching routing rules39(285) INFO: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} carrierroute [cr_func.c:197]: set_next_domain_on_rule(): next_domain is 47987 Carrier route rewrites the failover carrier 39(285) INFO: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} carrierroute [cr_func.c:706]: cr_do_route(): uri 14371234567 was rewritten to sip:14371234567@sip.primaryprovider.com, carrier 1, domain 47987 Before http_async_query rd and ru are still the failover carrier 39(285) INFO: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} <script>: [callid: 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn] - [cfg:2976] - Debug testing ----- rd is sip.primaryprovider.com ----- ru is sip:14371234567@sip.primaryprovider.com 39(285) DEBUG: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} http_async_client [async_http.c:469]: async_send_query(): transaction suspended [5261:1830449764] 39(285) DEBUG: {1 18398 INVITE 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn} http_async_client [async_http.c:625]: async_push_query(): query sent [ https://authn-uat.ccid.neustar.biz/ccid/authn/v2/identity?apiKey=randomkey] (0x7fdcad097e60) to worker 1 However, when the route is being called after the http_async_query it changes to the primary one: 26(272) DEBUG: tm [t_lookup.c:1612]: t_lookup_ident_filter(): transaction found 26(272) DEBUG: http_async_client [async_http.c:235]: async_http_cb(): resuming transaction (5261:1830449764) 26(272) DEBUG: tm [t_lookup.c:1612]: t_lookup_ident_filter(): transaction found 26(272) INFO: <script>: [callid: 8EmmsLqNuMRYBduMqFgX3w4JHAn4C2xn] - [cfg:2995] - Debug testing ----- rd is 1.2.3.4 ----- ru is sip:14371234567@1.2.3.4:5061;transport=TLS Due to this, call keeps going to the primary and it fails if ( http_async_query(STIRSHAKEN_AS_URL, "AS_RESPONSE") == -1 ) { xlog("L_ERR ", "[cfg:$cfg(line)] Failed to connect AS service for token $fu -> $tu \n"); return; } route[AS_RESPONSE] { xlog("L_INFO", "[callid: $ci] - [cfg:$cfg(line)] - Debug testing ----- rd is $rd ----- ru is $ru\n"); if ($http_ok) { xlog("L_INFO", "[cfg:$cfg(line)] Resuming outbound call transaction for $fu -> $tu Received - $http_rb \n"); # Add identity and Date headers if (jansson_get("identity", $http_rb, "$var(identity)")) { insert_hf("Identity: $var(identity)\n", "Content-Length"); } if (jansson_get("date", $http_rb, "$var(date)")) { if ($hdr(Date) != $null){ remove_hf("Date"); } insert_hf("Date: $var(date)\n", "Identity"); } } else { xlog("L_ERR", "[cfg:$cfg(line)] Resuming outbound call transaction.

Kamailio hang Issue
by satyaprakash ch 06 Aug '24

06 Aug '24

Hi, We are encountering a hang issue after deploying the following code: *route(DLG_MANAGE);* *if ($dlg_var(voip_id) == $null) { $dlg_var(voip_id) = $hdr(X-Voip-ID);}route[DLG_MANAGE] { if (is_method("INVITE")) { dlg_manage(); }}* This code includes the set_dialog_profile. We have this setup with 2 proxy servers with DMQ enabled, but the issue only occurs on one proxy. When the Kamailio proxy hangs, no logs are written. If you have any suggestions to resolve this issue, please help. Thanks.

Kamailio-IMS: After a abornamal Call, other call is not working (even after a new registration)
by deep.upreti＠gmail.com 05 Aug '24

05 Aug '24

Hello, Can anyone help me to resolve one issue? scenario is - 1- Register two UE (UE-A and UE-B) 2- Call from UE-A to UE-B for a specific duration (lets say: 100 seconds) 3 Verify if call is working: Answer is YES, call is working. 4. shutdown the eNB 5. Observation: No BYE/De-registration message is not coming as expected. 6. Again start eNB and register same UE (UE-A and UE-B) 7. Register UE-A and UE-B both 8. It will not remove previous contacts or not updating the reg-state. 9. I am running with Rx enable mode.

Multiple TLS connections to the same IP:Port
by Nick Digalakis 05 Aug '24

05 Aug '24

Hello everyone, I am trying to use a single Kamailio server to register to multiple MS Teams Direct Routing endpoints. The config snippet I am using is this: sht_iterator_start("i1", "teams-endpoints"); while(sht_iterator_next("i1")) { $var(teams_endpoint) = $shtitkey(i1); $xavp(tls=>server_name) = $var(teams_endpoint); $xavp(tls[0]=>server_id) = $var(teams_endpoint); $uac_req(method)="OPTIONS"; $uac_req(ruri)="sip:sip.pstnhub.microsoft.com:5061;transport=tls"; $uac_req(furi)="sip:" + $var(teams_endpoint); $uac_req(turi)="sip:sip.pstnhub.microsoft.com:5061;transport=tls"; $uac_req(hdrs)="Contact: <sip:" + $var(teams_endpoint) + ":" + "5061" + ";transport=tls>\r\n"; ### Create a unique Call-ID based on the Timestamp and the Message Body in MD5 $var(unhashed_cid) = $TV(Sn) + $mb + ""; $uac_req(callid)=$(var(unhashed_cid){s.md5}); uac_req_send(); } sht_iterator_end("i1"); When the HTable has only one endpoint, everything works fine. When I add a second endpoint, the first one continues to work but the second one failing with the error from Microsoft: Q.850;cause=63;text="85babcde-e0b5-4a85-8f4a-12345678c9ae;SBC certificate is not issued correctly. Provided trunk FQDN 'endpoint-02.domain.com' is not included in certificate's CN or SAN list. Certificate allows following FQDNs only: endpoint-01.domain.com. After some digging around, I realized that all endpoint after the first fail because Kamailio is re-using the same TLS connection for all subsequent OPTIONS as well, but of course the connection has been established with the certificate of the first endpoint. I have tested the certificates by switching around the first endpoint, so that shouldn't be a problem. Is there any way I can force it to establish a new TCP/TLS connection for each subsequent request? Any help would be much appreciated, I have been pulling my hair out with this one!

How to log datetime in files
by 陈子妍 04 Aug '24

04 Aug '24

Hello! I am working on with Kamailio, I have already understood to add log prefix like `log_prefix="NAT {$rm $mt $hdr(CSeq) $ci}: "`, but I also want to record event time, so how can I config `datetime` in log files. Thanks~

Why does $T(id_index) return 0 even though t_suspend() is executed successfully?
by mm e 01 Aug '24

01 Aug '24

if(t_suspend()) { $dlg_var(start_time) = $timef(%Y/%m/%d %H:%M:%S); xlog("L_NOTICE", "==> processing suspended in transaction [$T(id_index):$T(id_label)] "); } else { xlog("L_ERR", "t_suspend err"); exit; } Sometimes, I get this log==> processing suspended in transaction [0:13614] "，as far as I know, 0 means that the value cannot be obtained. Executing t_continue(tindex, tlabel, rtname) with parameter 0 will fail.by the way, It's a question of probability.

Hello Daniel, Regarding your question, I think only the avp(msg) should be destroyed as others avp's can be used elsewhere in the script.

31 Jul '24

Hello, I'm using the async_task_group_route for async module to handle some invites, when testing with sipp tools, I got some Dead call error message and after investigating It seems that for the same invite I sent multiple 302 message to sipp because the ACK sent by sipp was not handle before thr retr_timer1 & retr_timer2. Please can you help me to free the transaction after sending the first 302 ? Thank you in advance.
