by arish haque 25 Oct '19

25 Oct '19

Hi all, No Audio flows between the two parties when one side resumes the call after putting on hold. Configuration - WebRTC <--> Kamailio <--> Asterisk Below is the warning I'm getting in asterisk console WARNING[32388]: chan_sip.c:10425 process_sdp: Declining non-primary audio stream: audio 10596 UDP/TLS/RTP/SAVPF 107 103 104 9 0 8 106 105 13 110 112 113 101 Is this a codec issue or something else. Thanks, Arish

driver error: Can't connect to MySQL server with kamailio 5.3.x and mysql-config-groups
by Karsten Horsmann 23 Oct '19

Hi List, i updated one of my testing kamailios from 5.2.x to latest 5.3.x. After restarting the process, i got an mysql error that the server "kamailio" is not found. I use the config-feature of my.cnf config-group names within the kamailio.cfg I can start my kamailio 5.3.x installation with "normal username:password@host" definitions for DBURL.

MS Teams Direct routing with kamailio
by Karsten Horsmann 23 Oct '19

23 Oct '19

Hello List, i search for the right place in kamailio to manipulate the dispatcher OPTIONS packets to add an Contact header. For uac generated traffic i can use the event_route[tm:local-request] from the tm module. But how can i manipulate kamailio *self* generated OPTION pings from the dispatcher? OPTIONS request for MS Teams must contain the Contact header of such a format: Contact: <sip:SBC_FQDN:5061;transport=tls> I follow this guide (for opensips) and try to adapt that step by step to kamailio: https://blog.opensips.org/2019/09/16/opensips-as-ms-teams-sbc/ CentOS 7 / kamailio 5.2.x (and maybe soon 5.3.x) / rtpengine -- Cheers *Karsten Horsmann*

Unable to use BLF

Hi all, This is many days we are trying many things and reading many threads :) We also re installed a simple brand new kamailio to be sure everything is ok. In fact, with sngrep we can see "subscribe" arriving on kamailio but on syslog we have a critical error : Oct 23 10:08:42 GTO-Temp01 kamailio[2004]: 20(2027) exec: {1 29 SUBSCRIBE 3135373137353930373733323337-joash9r9lnre} *** cfgtrace:request_route=[PRESENCE] c=[/usr/local/etc/kamailio/kamailio.cfg] l=770 a=24 n=handle_subscribe Oct 23 10:08:42 GTO-Temp01 kamailio[2004]: 20(2027) CRITICAL: {1 29 SUBSCRIBE 3135373137353930373733323337-joash9r9lnre} <core> [core/mem/q_malloc.c:494]: qm_free(): *BUG: bad pointer 0xa (out of memory block!) *called from presence: *subscribe.c*: handle_subscribe(1040) - ignoring We tried to start kamailio with many more memory (x4) and this is the same.

mysql create user and grant privileges
by Daniel-Constantin Mierla 22 Oct '19

22 Oct '19

Hello, the mysql server version 8 is no longer supporting creating the user and granting privileges in the same statement, they have to be separate. I checked the mariadb specs and they seem to support also the separate creation of user and granting privileges in two statements. I pushed the changes in kamdbctl to master branch via commit: - https://github.com/kamailio/kamailio/commit/c0879add55bef77703f2259f224b4a1… The reason I am writing here is to see if anyone is aware of some (old) versions of mariadb or mysql servers that do not support the creation and grant in two steps. If yes, then we can add a config option in kamctlrc to do one or the other variants. But for now I did it only with the new style, as it seems to be supported everywhere by latest versions, to avoid unnecessary option to keep also the old style.

[Dialog] Removing entries from dialog memory
by Julien Klingenmeyer 21 Oct '19

21 Oct '19

Hi, I am wondering if there is any way to remove an entry from the active dialog list? I mean, assuming that Kamailio did not get any BYE related to a call for some reason and that I want that call to be “killed” from dialog memory before reaching the lifetime timeout. What I already tried with no success: sending a request to Kamailio catched by a dedicated route of the script then: * using the dlg_get function (with the target call as parameter) then send_bye function (then dropping the BYE request generated by the dialog module in the onsend_route with the drop function): no success. Dialog module correctly generates BYE requests but dialog related to the call is kept in memory until its lifetime timeout (and BYE requests are not dropped in the onsend_route either). * using the dlg_get function then dlg_set_timeout to set a very low timeout value for that particular call. No successs: Trying to update a bogus dlg as critical error. Could some RPC commands or whatever help me to accomplish what I try to do? Thanks Julien

pv_buffer_size limit
by Sergiu Pojoga 20 Oct '19

20 Oct '19

Hi ppl, I'm testing this external app (cgrates, you all know it) that talks to Kamailio via evapi. Every *n* minutes the app sends an evapi request to Kamailio which returns back the list of all dialogs like so: jsonrpc_exec('{"jsonrpc":"2.0","id":1, "method":"dlg.list","params":[]}'); evapi_relay("{\"event\":\"CGR_DLG_LIST_REPLY\", \"jsonrpl_body\":$jsonrpl(body)}"); The problem is that the size of *$jsonrpl(body)* PV is limited by Kamailio's *pv_buffer_size* setting. My math shows that a single dialog is about 1KiB of json data. *Problem*: Kamailio fails to start with a *pv_buffer_size *higher than 117 KiB (119808 bytes), which in turn rends the system's limit to about 117 simultaneous calls... pretty sad. Below find the error when trying to start Kamailio with higher values: 0(17080) ERROR: <core> [core/mem/q_malloc.c:291]: qm_find_free(): qm_find_free(0x7f02275c5010, 120832); Free fragment not found! 0(17080) ERROR: <core> [core/mem/q_malloc.c:425]: qm_malloc(): qm_malloc(0x7f02275c5010, 120832) called from core: core/pvapi.c: pv_init_buffer(2069), module: core; Free fragment not found! 0(17080) ERROR: <core> [core/pvapi.c:2072]: pv_init_buffer(): cannot init PV print buffer slot[39] Is there a workaround for this? Thanks, --Sergiu
