Getting the name of an already set onreply_route
by Denys Pozniak 14 Oct '24

14 Oct '24

Hello! Is it possible to find out the name of the onreply_route that was set before? Something like this: t_on_reply("MANAGE_REPLY"); ... if ( t_is_set("onreply_route") ) { get_onreply_route_name(); ... } -- BR, Denys Pozniak

Via header force change protocol to TLS?
by Anthony Alba 30 May '24

30 May '24

I have kamailio behind a TLS termination proxy so the sockets are correctly deduced to be TCP. However the clients only talk TLS to the proxy and are confused when the top Via header added by Kamailio is TCP. Is there a way for Kamailio to forcibly pretend its protocol is TLS? Like advertised_address but "advertised_protocol" instead. (With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio and continues to use the persistent TLS transport to proxy. Linphone fails because it tries to honor TCP in Via and is unable to establish TCP transport). BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy as TCP even though the contact addresses specify transport=TLS.

Dialog and DMQ on restart
by Björn Klasen 25 Mar '24

25 Mar '24

Hi everybody, I'm just testing Kamailio 5.4.1 with dialog replication over DMQ. This seems to work very good. Dialogs are replicated without problems. When I'm restarting one node I would have expected, that all dialogs are synced again, just like in dmq_usrloc. But this does not happen. After a restart the nodes dialog-list is empty. Did I miss somethin? Is there a special parameter that I have to set?

5.6.4 debian htable dbmode=1 not writing at shutdown
by Bernd Krueger-Knauber 29 Nov '23

29 Nov '23

Hi, I have still the problem that my htables are not written into a sqlite db when I shutdown kamailio. Manual writing via: kamcmd htable.store ... is working. As I can see in the logs with highest loglevel, the function destroy() is never called. ht_db_url.len is > 0 ht_db_init_con() should work, else nothing would work with the db. But I can not see the debug messages from ht_db_open_con() Any ideas? Best regards, Bernd

error in parsing HTTP messages
by sigxcpu＠gmail.com 02 Oct '23

02 Oct '23

Hello, In reference to this issue https://github.com/kamailio/kamailio/issues/3081 I've been advised to set http_reply_parse to "no" which I did (and it is the default value anyways). # grep http_reply_parse /etc/kamailio/kamailio.cfg http_reply_parse=no After setting this, I still get these parsing errors: { "idx": 23, "pid": 102, "level": "ERROR", "module": "core", "file": "core/parser/msg_parser.c", "line": 748, "function": "parse_msg", "logprefix": "", "message": "ERROR: parse_msg: message=<HTTP/1.1 100 Continue\r\n\r\nHTTP/1.1 200 OK\r\ndate: Wed, 26 Jul 2023 16:43:19 GMT\r\ncontent-length: 224\r\ncontent-type: text/plain; charset=utf-8\r\n\r\n{\"result\": {\"ruri\":\"\",\"fU\":\"\",\"tU\":\"\",\"privacy\":\"\",\"identity\":\"\",\"error\":{\"code\":0,\"message\":\"\"},\"mb\":\"\",\"Headers\":null,\"encrypted\":\"\",\"sipsScheme\":\"\",\"attestation\":\"\",\"authUser\":\"\",\"authPassword\":\"\",\"disableStirShaken\":\"\"}}>" } Is there anything that I am missing beyond setting that parameter? Thank you, Alexandru

Increase MAX_BRANCHES_LIMIT
by Lars Jansson 18 Sep '23

18 Sep '23

Hi, I am building a configuration script where for some traffic flows parallel forking will be needed, and in this case I need to go beyond the default max limit of the max amount of branches. Apart from this specific case the traffic load that kamailio will need to handle is very low, let's say just one second here and there with up to 5 concurrent calls at most. This limit is as far as I understand set here: usr/local/src/kamailio-5.6/kamailio/src/core/config.h And the default limit is: #define MAX_BRANCHES_LIMIT 32 /*!< limit of maximum number of branches per transaction */ Here are the questions I have related to this: 1) If I increase the value of this constant in config.h, how high is it reasonable to set this value and still have a stable system? 2) If I increase MAX_BRANCHES_LIMIT beyond 32, are there also other parameters that needs to be changed for the system to be able to cope, and if so whichparameters? Regards, Lars

Hello all, I want to save some credentials for different users I have that are being used in a digest authorization (INVITE), with different realms (I don't want the credentials to be hardcoded). I tried to look at how can I read into my kamalio.cfg from yaml/txt file, but haven't found the right module for this. Thanks in advance, Max
