[kamailio/kamailio] presence not work proper with subs_db_mode = 2 (#2540)

23 Nov '23

Hello I have problem with Kamailio presence,i have configure my kamailio.cfg to handle dialog presence and facing issue in case of subs_db_mode = 2 in case of mode 2 facing following presence issue. 1) after hangup presence is still up 2) sometimes stuck in ringing state 3) sometime presence not came..etc but in case of subs_db_mode = 3 (DB ONLY) mode presence working fine not facing any issue with this mode. I noticed that sometimes Kamailio will throw following message during PUBLISH processesing and it will not generate appropriate NOTIFY i also verify in active watcher subscription is thare for that user and also proper entry in dialog table. MSG during PUBLISH processesing and it will not generate appropriate NOTIFY Oct 30 07:42:10 NC-HOSTED-1 /usr/local/sbin/kamailio[2409]: DEBUG: presence [notify.c:1444]: publ_notify(): Could not find subs_dialog kamailio.cfg param modparam("pua", "db_url", DBURL_KAMAILIO) modparam("pua", "db_mode", 2) modparam("pua", "update_period", 100) modparam("pua", "dlginfo_increase_version", 1) modparam("pua", "default_expires", 3600) modparam("pua", "fetch_rows", 1000) modparam("pua", "outbound_proxy", SERVER_IP) modparam("dialog", "db_url", DBURL_KAMAILIO ) modparam("dialog", "db_mode", 1) modparam("dialog", "db_update_period", 260) modparam("dialog", "db_fetch_rows", 500) modparam("pua_dialoginfo", "include_callid", 1) modparam("pua_dialoginfo", "send_publish_flag", 8) modparam("pua_dialoginfo", "caller_confirmed", 0) modparam("pua_dialoginfo", "include_tags", 1) modparam("pua_dialoginfo", "use_pubruri_avps", 1) modparam("pua_dialoginfo", "include_localremote", 1) modparam("pua_dialoginfo", "override_lifetime", 300) modparam("pua_dialoginfo", "pubruri_caller_avp", "$avp(s:puburis_caller)") modparam("pua_dialoginfo", "pubruri_caller_dlg_var", "pubruri_caller") modparam("pua_dialoginfo", "pubruri_callee_dlg_var", "pubruri_callee") modparam("pua_dialoginfo", "pubruri_callee_avp", "$avp(s:puburis_callee)") modparam("presence_dialoginfo", "force_single_dialog", 1) modparam("presence", "db_table_lock_type", 0) modparam("presence", "db_url", DBURL_KAMAILIO) modparam("presence", "db_update_period", 5) modparam("presence", "send_fast_notify", 1) modparam("presence", "clean_period", 100) modparam("presence", "subs_db_mode", 2) //modparam("presence", "subs_db_mode", 3) modparam("presence", "timeout_rm_subs", 1) //new/ //modparam("presence", "notifier_processes", 2) //new// modparam("presence", "notifier_poll_rate", 20) //new// modparam("presence", "waitn_time",1) modparam("presence", "fetch_rows", 1000) modparam("presence", "presentity_table", "presentity") modparam("presence", "active_watchers_table", "active_watchers") modparam("presence", "watchers_table", "watchers") modparam("presence", "max_expires", 3600) modparam("presence_xml", "db_url", DBURL_KAMAILIO) modparam("presence_xml", "force_active", 1) logic for presence request_route { if(is_method("PUBLISH") || is_method("SUBSCRIBE")) { route(HANDLE_PRESENCE); } } route[HANDLE_PRESENCE] { if (! t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if( is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); } exit; } route[RELAY] { if(is_method("INVITE|BYE|UPDATE|CANCEL|ACK")) { $avp(t_ext) = $tU ; $avp(domain) = $fd ; $avp(et) = $_s(sip:$avp(t_ext)@$avp(domain)) ; $avp(s:puburis_callee) = $avp(et); setflag(8); dlg_manage(); } } -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] tm remap_503_500 breaks dialogs (#2405)
by geejay101 23 Nov '23

23 Nov '23

### Description Apparently the remapping of 503 to 500 codes in the tm module does also change the to-tag. This behaviour breaks dialogs with yate and therefore calls hang and the 503 remains unacknowledged. Removing to-tags seems to contradict RFC3261 "12 Dialogs A dialog is identified at each UA with a dialog ID, which consists of a Call-ID value, a local tag **and a remote tag**…" Due to the bug the UA cannot identify the dialog the 500 belongs to. Therefore the dialog remains open and Kamailio keeps repeating 500 messages. ### Troubleshooting After disabling the 503 to 500 remapping with modparam("tm", "remap_503_500", 0) dialogs get properly terminated . #### Reproduction 503 to 500 remapping is enabled by default. Inspect the to tags of the incoming 503 and outgoing 500 messages. #### Debugging Data Henning added this comment: Apparently, this is the way the code works: t_reply.c: if (relayed_code==503 && tm_remap_503_500){ /* replace a final 503 with a 500: * generate a "FAKE" reply and a new to_tag (for easier * debugging)*/ ### Possible Solutions Dont change the to-tag ### Additional Information kamailio -v version: kamailio 5.2.3 (x86_64/linux) c36229 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: c36229 compiled on 10:34:54 Jun 13 2019 with gcc 4.8.5 * **Operating System**: CentOS Linux release 7.6.1810 (Core) 3.10.0-957.12.2.el7.x86_64 -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] load_crl takes 90 seconds to complete it execution with crl file size of 4MB !!! (#2312)
by maheshb2487 23 Nov '23

23 Nov '23

### Description Am using Kamailio 5.1.9 version, In my tls.cfg i have one client and server profile, along with default client and server profile. I have crl enabled for the non default client and server profile , the crl file size is 4 MB in my case. I have 22 child tcp process. With this what i observe is load_crl is taking close to 90 seconds to finish its execution and return. ### Expected behavior load_Crl function should not take 90 seconds to complete its execution. probably it should take in the range of 10-15 seconds to complete its execution or even lesser. #### Actual observed behavior load_Crl function is taking 90 seconds to complete its execution. #### Debugging Data It is very clear from the code, its because of this for loop. time taken to complete load_Crl execution is 90 seconds procs_no=get_max_procs(); for(i = 0; i < procs_no; i++) { if (SSL_CTX_load_verify_locations(d->ctx[i], d->crl_file.s, 0) != 1) { ERR("%s: Unable to load certificate revocation list '%s'\n", tls_domain_str(d), d->crl_file.s); TLS_ERR("load_crl:"); return -1; } store = SSL_CTX_get_cert_store(d->ctx[i]); X509_STORE_set_flags(store, X509_V_FLAG_CRL_CHECK | X509_V_FLAG_CRL_CHECK_ALL); } Is there a way this can be enhanced or as per the current kamailio design this is a must to do for each and every profile and its ssl context array list for each process and for every profile. The same logic is seen in other load functions as well, for example load_cert, load_ca_list, load_crl, set_cipher_list, set_verification, set_ssl_options, set_session_cache, ksr_tls_fix_domain, #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions Reply from Henning Westerholt on posting this problem to Users Mailing list "But the code could be probably also improved, maybe it is possible to parallelize it. You can open a feature request about it," ### Additional Information Kamailio 5.1.9 version * **Operating System**:  ``` Linux Kernel version : 3.10.0-693.el7.x86_64 Centos version : CentOS Linux release 7.4.1708 (Core) CPU : 2 cores with model name : Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz [root@miv5000 ~]# cat /proc/meminfo MemTotal: 3882076 kB MemFree: 811244 kB MemAvailable: 2320356 kB Openssl verison : OpenSSL 1.0.2k-fips 26 Jan 2017 ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Presence module RPC command to dump active watchers from memory. (#2188)
by VolodyaIvanets 23 Nov '23

23 Nov '23

### Description Explain what you did, what you expected to happen, and what actually happened. I'm looking at using presence module with **subs_db_mode** parameter set to 0-2 where it uses memory to store and query active watchers. I noticed that sometimes Kamailio will throw following message during PUBLISH processesing and it will not generate appropriate NOTIFY for watchers: `DEBUG: presence [notify.c:1234]: publ_notify(): Could not find subs_dialog ` RPC command to dump current active watchers will be helpful during troubleshooting. Currently with **subs_db_mode** set to 0 you can not tell for sure if subsciption already expired or not. And with **subs_db_mode** set to 1 or 2 you can get information from DB with delay. This command will also allow to clarify subscriber _domain_ value which if I understood correctly must match domain from presentity. Thanks a lot! -- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2188

[kamailio/kamailio] dialog and dmq in db_mode 2 - dialog_vars entries created and not deleted (#2093)
by Henning Westerholt 23 Nov '23

23 Nov '23

Dialog and DMQ in db_mode 2 - dialog_vars entries created and not deleted. Szenario: two proxies in DMQ synchronization with additional database. Configuration identical on both machines: ``` root@proxy-1:/etc/kamailio# grep dialog kamailio.cfg loadmodule "dialog.so" modparam("dialog", "db_mode", 2) modparam("dialog", "db_update_period", 10) modparam("dialog", "enable_dmq", 1) modparam("dialog", "default_timeout", 60); modparam("dialog", "send_bye", 1) ``` Call is placed on proxy1. Proxy1 handles the call, and synchronize the dialog data to proxy2. Proxy2 is able to list the dialog with kamcmd dlg.list etc.. Proxy2 will not write the dialog into dialog table, but will write the dialog variables to the dialog_var table: ``` root@proxy-2:/etc/kamailio# mysql kamailio MariaDB [kamailio]> select * from dialog; select * from dialog_vars; Empty set (0.00 sec) +----+------------+---------+-------------+---------------------------------+ | id | hash_entry | hash_id | dialog_key | dialog_value | +----+------------+---------+-------------+---------------------------------+ | 9 | 3479 | 1648 | _uac_fu | sip:customer-1@sip.XXXX.net | | 10 | 3479 | 1648 | _uac_funew | sip:batman@XXX.org | | 11 | 3479 | 1648 | _uac_fdp | | | 12 | 3479 | 1648 | _uac_fdpnew | | | 13 | 3479 | 1648 | _uac_to | sip:customer-2@sip.skalatan.net | | 14 | 3479 | 1648 | _uac_tonew | sip:robin@XXX.org | | 15 | 3479 | 1648 | _uac_tdp | | | 16 | 3479 | 1648 | _uac_tdpnew | | +----+------------+---------+-------------+---------------------------------+ 8 rows in set (0.00 sec) ``` Because of this the dialog_vars will grow for every call. In db_mode 1 this dialog_vars entries (and also dialog entries) are not written. I suggest to adapt db_mode 2 with DMQ to the same behaviour. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] CDP / IMS Diameter Server Module- diameter_request() function fails to send/forward request (#2035)
by Nick 23 Nov '23

23 Nov '23

Hi Kamailio team, I'm attempting to use Kamailio as a Diameter Routing Agent, but I can't seem to get the diameter_request() function to actually _send_ the diameter request, instead I get a warning about no JSON Response: > WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response Even when relaying received data without modifying it. I posted this issue on the mailing list but have had no responses. Since then I've run a bunch more tests on a few different versions of Kamailio with a few different Diameter peers with the same result. ### Description The IMS Diameter Server Module's[ diameter_request() function](https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_… fails to send, reporting "No JSON Response" even when fed unmodified received data into it. ### Troubleshooting Initially I was trying to use CDP & IMS Diameter Server Module to create & send Diameter messages, I thought my formatting in the message (the Diameter Message (as JSON)) was incorrect. as I was getting: > WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response When trying to send the request. To rule out my JSON formatting being the issue I configured two Diameter Peers in Kamailio: >From one Diameter peer, I sent a Diameter request to Kamailio. Kamailio is configured to receive the Diameter request, and without modifying the message body ($diameter_request), put that message into the message of the the diameter_request() so as to rule out formatting errors in the message, just a relay of the message, but this also fails to send. I also included a series of checks to confirm the peer to receive the relayed message was online and capable of handling the specified Diameter application, all of which passed. I've defined the peers in the diametercfg.xml config file, and they're all showing as online when I do a "kamcmd cdp.list_peers": FQDN: ims-hss.localdomain Details: { State: I_Open Disabled: False Last used: 0 Applications: { appid:vendorid: 16777216:10415 appid:vendorid: 16777216:4491 appid:vendorid: 16777216:13019 appid:vendorid: 16777216:0 appid:vendorid: 16777217:10415 appid:vendorid: 16777221:10415 } } Here's a simplified version of my event_route[diameter:request], showing I simply receive the diameter request and then try to send it straight back out using the diameter_request() function: ``` event_route[diameter:request]{ xlog("Got diameter message"); diameter_request("ims-hss.localdomain", $diameter_application, $diameter_command, $diameter_request); xlog("Forwarded Diameter Request"); } ``` When tailing syslog I see the "Got diameter message" entry but not the "Forwarded Diameter Request", which suggests it's not getting past the diameter_request(), instead I just see the: > WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response Packet captures show Kamailio receives the request but never relays it. The source of avp_helper.c shows the warning is called if the length of the JSON is <= 0, but as I'm feeding back out what I've received it shouldn't be 0, an no recent major changes to the source, so I'm stumped as to why it's catching this. I've attached a full copy of the config files below. #### Reproduction I've tried this with a few different Diameter servers, but I can reproduce it with two FreeDIAMETER peers configured in Diameter CDP Config XML, I've also tried with one Kamailio CDP based peer and using xhttp to call the diameter_request() function with the same results. #### Log Messages Copy of relevant SysLog: https://pastebin.com/ZY8z2kd4 ### Additional Information Full Kamailio Config: https://pastebin.com/afgqUfWr Diameter CDP Config XML: https://pastebin.com/bVrBG8mG Relevant Syslog: https://pastebin.com/ZY8z2kd4 Kamcmd cdp.list_peers: https://pastebin.com/cKi4JAHC Kamailio 5.1.2 on Ubuntu 18.04 installed from Repos. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] mod pua (dialoginfo) etag race conditions (#2048)
by Laszlo 23 Nov '23

23 Nov '23

I'm observing the following scenario: * mod_dialog callbacks trigger 2 or more times (nearly) simultaneously for the same dialog * pua_dialoginfo sends PUBLISH 1, referencing etag A * pua_dialoginfo sends PUBLISH 2, referencing etag A * presence_dialoginfo processes PUBLISH 1, replies with new etag B * presence_dialoginfo processes PUBLISH 2, replies with a 412 (because etag A no longer exists) * pua_dialoginfo receives the 412 and re-tries it as PUBLISH 3 ("sent a PUBLISH within a dialog that no longer exists, send again an intial PUBLISH") * presence_dialoginfo processes PUBLISH 3, and may or may not accept it The situation as described is not ideal since it'll fill up your logs with errors, but isn't critical per se. Much more problematic is when there are more than 2 PUBLISHes generated for the same dialog simultaneously, as this can cause a (near) infinite race between the various PUBLISH requests all fighting to update the same etag. For example, 10 PUBLISH are sent out for etag A; all but one are rejected with a 412; then the other 9 keep on bouncing back and forth between pua_dialoginfo and presence_dialoginfo because they do not share the same view on the dialog's latest etag. Even worse is when presence_dialoginfo is rejecting *all* incoming PUBLISHes with a 412, for example because of a database/memory/replication problem or a malformed request. A `t_reply("412", "Not today")` in the presence_dialoginfo server, combined with a single PUBLISH from pua_dialoginfo is enough to reproducibly brick the pua_dialoginfo server because it runs into critical memory fragmentation levels. I think there are multiple ways to fix or alleviate this problem. ## pua generic * pua (publ_cback_func) should not retry 412-failed PUBLISHes indefinitely, but e.g. at most once * pua should not generate simultaneous PUBLISHes for the same presentity. It should delay PUBLISH 2 until PUBLISH 1 is either (permanently) accepted or rejected; or it should discard PUBLISH 2 immediately when it is generated. * Perhaps make handling of 412 replies more fine-grained. Currently every 412 reply is handled like this ("sent a PUBLISH within a dialog that no longer exists"), while that statement doesn't apply to all possible 412 replies. ## pua_dialoginfo specific * pua_dialoginfo currently subscribes to a lot of mod_dialog callbacks. For example subscribing to both DLGCB_CONFIRMED and DLGCB_CONFIRMED_NA will always get you two (rapidly succeeding) PUBLISHes with exactly the same contents. Subscribing to DLGCB_REQ_WITHIN means you'll get a new PUBLISH for every re-INVITE such as hold/unhold or codec negotiation, which is useless in many usecases. It would be helpful to allow configuring pua_dialoginfo with a list of callbacks to subscribe to. * With or without a smaller set of mod_dialog callbacks, pua_dialoginfo can generate multiple PUBLISH requests with exactly the same contents. Since pua is aware of the (last) state that it published for the presentity, it could compare if the newly generated PUBLISH is any different from the last known state, and discard it if it's not. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] kamctl - shell interpreter selection (#2019)
by Daniel-Constantin Mierla 23 Nov '23

[kamailio/kamailio] EVAPI: Better ability to remove dead clients (#1880)
by weili-jiang 23 Nov '23

23 Nov '23

### Description If an EVAPI client drops dead and silently closes its TCP connection, EVAPI is not notified in an acceptable time frame. The default OS TCP keep-alive parameters are generally far too long to be effective, and there is no way to override these using module or runtime configuration. Moreover, any attempts to put in a workaround is thwarted by the inability to close an arbitrary EVAPI connection from say, a timer event (since there is no way to specify a connection to close outside the EVAPI context). ### Expected behavior When an EVAPI client goes dead, the connection should be closed in the order of seconds (ideally configurable). The EVAPI should allow connections to be closed via scripting from any context. #### Actual observed behavior When an EVAPI client goes dead, the connection stays open (counting towards the maximum number of allowed clients). When the evapi_close is invoked from other contexts, nothing happens. #### Debugging Data #### Log Messages #### SIP Traffic ### Possible Solutions ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.2.1 (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 6.3.0 ``` * **Operating System**: Debian GNU/Linux 9 (stretch) ``` Linux 3b83b180f7c9 4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] tls connection terminated frequently when mongodb cluster member becomes unavailable (#1599)
by flo-eyeson-team 23 Nov '23

23 Nov '23

### Description Kamailio frequently terminates tls connections to sip clients, if db_mongodb database driver is used and one mongodb cluster member becomes unavailable. If one mongodb secondary is shutdown (or the primary and a promotion takes place) kamailio will terminate the tls connection to a sip-client (sends a FIN/ACK) after a short period of time (differs 20s to 180s). If a sip client reconnects, registration will succeed (so mongodb access is fine) but kamailio will terminate the tls connection shortly after. This situation happens as well if only the connection between kamailio and a secondary is blocked (the cluster members can still communicate with each other). I assume that the mongo-c's server discovery might be the culprit. Mongoc iteratively tries to connect to all servers in the mongoc-uri to update their status (`mongodb://mongodb-cluster2:27017,mongodb-cluster1:27017,mongodb-cluster0:27017/kamailio?authMechanism=MONGODB-X509&replicaSet=rs1&ssl=true&sslcertificateauthorityfile=mongo.ca&sslclientcertificatekeyfile=mongo.certkey`). Nonethless, mongoc's server discovery should be transparent to the kamailio client as long as a primary exists (and this is the case). No reason to terminate tls client connections.  ### Troubleshooting #### Reproduction  1. Setup a mongodb cluster with 3 members. 2. Setup kamailio with tls using db-mongodb via tls. Note: The mongodb-uri must contain all three members, e.g. `mongodb://mongodb-cluster2:27017,mongodb-cluster1:27017,mongodb-cluster0:27017/kamailio?ssl=true`) 3. Connect/register a sip client via tls. 4. Stop one member. 5. Clients will receive a ready error on its tls connection. #### Log Messages  The db_mongodb kamailio logs don't reveal any errors. Operations are normal. The only thing which is shown in the logs is TLS read:error. As seen below. ``` Jul 23 14:22:09 bda3e8fce481 /usr/local/sbin/kamailio[318]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS read:error:140E0197:SSL routines:SSL_shutdown:shutdown while in init Jul 23 14:22:09 bda3e8fce481 /usr/local/sbin/kamailio[318]: ERROR: <core> [core/tcp_read.c:1485]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7fa9b6343210 r: 0x7fa9b6343290 ``` A wireshark trace reveals that kamailio closes the tcp connection (FIN/ACK).

[kamailio/kamailio] tmx: t_reuse_branch() doesn't copy $du into new branch (#1264)
by Sebastian Damm 23 Nov '23

23 Nov '23

### Description When using the t_reuse_branch() function after a branch failure, Kamailio doesn't send out the call again if $du was filled and differed from $ru. Instead, Kamailio tries to send the call directly to $ru. I would expect that the call gets sent out the same way as the original call. ### Troubleshooting #### Reproduction You need a setup like this: UAC1 K(LB) <=> K(Proxy/Registrar) <=> K(LB) => UAC2 When a UAC registers, the Path module is used to save the LB (Loadbalancer) for outbound calls. When UAC1 calls UAC2, the original call gets sent through K(LB) to UAC2. However, if the first call gets rejected and the call gets retried through branch failure route, K(Proxy/Registrar) tries to send the call directly to the request URI. In your branch_route add a reference to a branch failure route: ```t_on_branch_failure("samplename");``` Then add a branch failure route like this: ```event_route[tm:branch-failure:handle_tls_branch] { if(t_check_status("488")) { if (isbflagset(0) && !isbflagset(1)) { t_reuse_branch(); setbflag(1); t_relay(); } } }``` When filling $du manually before sending out the call again, everything works. ### Possible Solutions The original destination URI should be copied to the reused branch. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 4.4.5 (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 4.7.2 ``` But from what I see in source code, the devel version still copies the same value. * **Operating System**:  ``` Debian Wheezy ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Solve the high potential of having conflicts for internal dialog id in multiple simultaneous kamailio instances (#1500)
by alexsosic 23 Nov '23

23 Nov '23

Regarding the issue 1274 (https://github.com/kamailio/kamailio/issues/1274) there's a problem in highly scalable environments to avoid conflicts in storing dialogs in the same DB. As @miconda pointed out: > The internal id is made from two integers, hash entry and hash id (h_entry, h_id). h_entry is the index of the slot in the hash table used to store the dialog structure, computed by hashing over call id. h_id is an incremented integer specific for each hash table slot. > > So, when loading a new record from database, if its h_id is not conflicting with an existing dialog on the same hash table slot, all is ok, otherwise the module is not going to work properly with two dialogs having same h_id. > > So, when loading a new record from database, if its h_id is not conflicting with an existing dialog on the same hash table slot, all is ok, otherwise the module is not going to work properly with two dialogs having same h_id. > > Among solutions I thought of: > > 1. have the servers generating non conflicting h_id, by having a start value different per server and an increment step larger than the number of servers. Iirc, here was at some point a similar attempt, but somehow didn't make it. Let's say one has two servers, first server starts allocating h_id from 1 and increments by 2 (e.g: 1, 3, 5, ...) and the seconds start from 2 and increments with 2 (2, 4, 6, ...). Those values can be set via mod params, eventually with an option to rely on server_id. > This should be the least intrusive in the other modules built on top of dialog. But it is rather rigid, with the example above, if one adds an extra server, it needs to reconfigure the old ones, so each server starts from either 1, 2 or 3 and increment by 3. Of course, one can set increment step to a larger value, like 100, and then has flexibility to deploy up to 1 hundred servers before having to reconfigure in case there is need for more server. > > 2. add server_id as the third field in the dialog id. It will require review of other modules using dialog and eventual code updates in those modules. One column to store the server_id needs to be added to dialog db tables. > > 3. switch from this conflicting id system to something like string unique ids, similar to what we have in usrloc records. This will require coding in other modules, changes to database schema, etc., so more work comparing with the above two, but could be the best in long term. It would be great to have the option 3 developed if possible but we would also be satisfied with the option 2 to have a third field, server_id, in the dialog id.

[kamailio/kamailio] allow more than one tcp/tls connection to same destination (#1107)
by juha-h 23 Nov '23

23 Nov '23

When K connects to another SIP proxy over TCP or TLS, the connection is shared for all requests to that destination. If the receiving SIP proxy is K, it means that only one worker process is handling all those requests. This may become a bottleneck if processing of requests is time consuming, e.g., because of DB operations. It should therefore be possible one way or another to establish more than one parallel TCP or TLS connections to the same destination. One solution could be based on a function call, such as t_forward_connect(number), to be called before t_relay specifying the desired number of parallel connections shared randomly by outgoing requests. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Presentity tabla, faster update when drop TCP/TLS connection (#915)
by jresende 23 Nov '23

23 Nov '23

Hello, I'm testing kamailio with a SIP client with presence support, when I get a connection drop from a client (i.e when the client lost the access to the Internet connection) I do not receive the change in the status to offline immediately, I just received when the timeout from the presentity database finishes. I know that I'm able to change the expiry parameter from the presentity table, but that increases my battery consumption and the data exchange, the same happens if I reduce the publish interval on the client side. The connection with the server are connected with the TLS or TCP. @miconda Suggested that a solution could be: "For TCP/TLS, what can work, it's to use tcpops module which can execute an event route when a tcp/tls connection is dropped. If you track the association of connection id with the call-id of the presence publish, then you may be able to do some tricks and lower the expires of the published presence state. I haven't had the time to see what's possible there, but could worth investing. An alternative would be to enhance presence module to behave as registrar/usrloc (which can delete contact records on connection drop) to expire documents when tcp/tls connection is closed (not sure if anyone already added it)." -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] support valgrind when *_MALLOC is used (#949)
by Victor Seva 23 Nov '23

23 Nov '23

As explain at https://www.kamailio.org/wiki/tutorials/troubleshooting/memory#pkg_with_sys… valgrind can be used to check memory leaks if kamailio is compiled without ``*_MALLOC``. I would like to support valgrind even if kamailio is compiled to use its own memory managers. In order to archive this, valgrind has to be informed of how those managers control the memory as described at http://valgrind.org/docs/manual/mc-manual.html#mc-manual.mempools -- You are receiving this because you are subscribed to this thread.
