Add a digest authorization with password and username (INVITE)
by Max Kemel 20 Jul '23

20 Jul '23

Hello, I would appreciate any help you can provide on this matter, I would like to make an outgoing INVITE request which will have a digest authorization with password and username. I was wandering around the Auth module to find the most fit method to build this header but hadn't found anything. Maybe I am missing something really obvious here, thanks for the help in advance Best regards, Max.

Re: WebRTC proxy with rtpengine - How to change from RTP to SRTP on 488 response
by Alex Balashov 18 Jul '23

18 Jul '23

I wouldn't do a delete in that situation; it might be simpler to just do another rtpengine_offer() on a <Call-ID, From-tag> tuple that RTPEngine already knows about, just as one would in a reinvite. I believe rtpengine_manage() would cover this situation as well. And yes, then just t_relay() anew! > On Jul 18, 2023, at 11:41 AM, Barry Flanagan <barry(a)flantel.com> wrote: > > On 18/07/2023 16:33, Alex Balashov wrote: >> Barry, >> >> Might it not be simpler to follow Richard's first suggestion in that thread, and simply catch the 488 response in a failure_route and re-issue a non-SRTP offer on another branch? > > hi Alex, > > Might be.

WebRTC proxy with rtpengine - How to change from RTP to SRTP on 488 response
by Barry Flanagan 18 Jul '23

18 Jul '23

Hi, I have implemented a WebRTC proxy using Kamailio and rtpengine, in front of Asterisk servers. I have an issue where I do not know in advance whether the Asterisk client is set to use RTP or SRTP. My implementation expects the web side to be SRTP and the Asterisk side plain RTP. However, if the asterisk side requires SRTP I receive a 488 Not Acceptable here. The same is true when an SRTP client from the Asterisk side dials out to the webrtc client, I need to catch whether the request is SRTP or RTP and generate rtpengine offer accordingly. This was discussed in github, with a description of a solution here: https://github.com/sipwise/rtpengine/issues/435#issuecomment-391937398 <https://github.com/sipwise/rtpengine/issues/435#issuecomment-391937398>- however I am unsure how to implement this. Does anyone have an example of how I can change the rtpengine SDP in such a case? Thanks -- -Barry

Kamailio 5.6.4 and htable dbmode=1

Hi, I just tried to use sqlite and htable to load and save the values. At start I can see in the log, that all parameters are correct and that htable want to load the values from the table. No errors. But if I stop kamailio, nothing is written to the tables. At start I can see: kamailio[]: DEBUG: <core> [core/modparam.c:112]: set_mod_param_regex(): 'htable' matches module 'htable' kamailio[]: DEBUG: <core> [core/sr_module.c:814]: find_param_export(): found <htable> in module htable [/usr/lib/x86_64-linux-gnu/kamailio/modules/htable.so] kamailio[]: DEBUG: <core> [core/modparam.c:128]: set_mod_param_regex(): found <htable> in module htable [/usr/lib/x86_64-linux-gnu/kamailio/modules/htable.so] kamailio[]: DEBUG: htable [ht_api.c:1046]: ht_table_spec(): htable [callpush] - dbmode [1] kamailio[]: DEBUG: htable [ht_api.c:1027]: ht_table_spec(): htable [callpush] - dbtable [userpush] kamailio[]: DEBUG: htable [ht_api.c:1036]: ht_table_spec(): htable [callpush] - expire [86400] kamailio[]: DEBUG: htable [ht_api.c:1041]: ht_table_spec(): htable [callpush] - size [10] kamailio[]: DEBUG: htable [ht_api.c:1084]: ht_db_load_tables(): loading db table [userpush] in ht [userpush] kamailio[]: DEBUG: htable [ht_db.c:232]: ht_db_load_table(): =============== loading hash table [userpush] from database [userpush] kamailio[]: DEBUG: db_sqlite [dbase.c:223]: db_sqlite_submit_query(): submit_query: select key_name,key_type,value_type,key_value from userpush order by key_name kamailio[]: DEBUG: <core> [db_query.c:72]: db_do_submit_query(): submitted query: select key_name,key_type,value_type,key_value from userpush order by key_name, result 0 kamailio[]: DEBUG: <core> [db_res.c:119]: db_new_result(): allocate 56 bytes for result set at 0x7f4882107938 kamailio[]: DEBUG: <core> [db_res.c:79]: db_free_columns(): freeing 0 columns kamailio[]: DEBUG: <core> [db_res.c:138]: db_free_result(): freeing result set at 0x7f4882107938 Ok, the file is empty, but it tries to load the data from the table. The table looks like: sqlite> .schema userpush CREATE TABLE userpush ( key_name TEXT, "key_type" INTEGER, value_type INTEGER, key_value TEXT ); I checked the source code and I saw that destroy() should be called. Inside is ht_db_open_con() called before ht_db_sync_tables(), were it happens. But I can even not see the debug message from ht_db_open_con() : LM_DBG("database connection opened successfully\n") and also not LM_ERR("failed to connect to the database\n"); For me it looks like, that the destroy() function is not called. Even with debug=3, I can only see: systemd[]: Stopping kamailio.service - Kamailio - the Open Source SIP Server... kamailio[]: INFO: <core> [main.c:854]: sig_usr(): signal 15 received systemd[]: kamailio.service: Deactivated successfully. systemd[]: Stopped kamailio.service - Kamailio - the Open Source SIP Server. I stopped kamailio with systemctl stop kamailio I'm sure that something was inside the htable before I stoped kamailio: { entry: 0 size: 1 slot: { { name: 07db580a6c13e798a5acc0d123d6e957897c8650b43f99d6d5cb9c2cb5ba4fa4 value: 3a28dcb73eb65722df5a261983b7692cecdca482bf8725032e46a0c6b89fb355 type: str } } } Any further ideas?

Using Kamailio in front of Freeswitch for load balancing REG and Calls
by Shah Hussain Khattak 12 Jul '23

12 Jul '23

Hello Awesome people, I have configured Kamailio in front of two Freeswitch servers. I am using the dispatcher module to load and balance the traffic between the two FS boxes. My dispatcher is configured in a round-robin fashion. If I send a register to my FS servers, the re-register post-challenge (401) message is routed to the second FS server and the registration fails. I want to check with you guys how are you handling this in your setups. I am sure a lot of companies are using Kamailio to load balance traffic toward the FS and Asterisk servers. UAC --- > Kamailio --- > FS1 REG ---- > REG ---- > REG 401 <---- 401 < ---- 401 re-register with authorization data: UAC --- > Kamailio --- > FS2 REG --- > REG ---- > REG 401 <---- 401 < ---- 401 it just create this loop and register fails. Ideally, I want Kamailio to send the re-register (with auth data) to the same FS server that challenged it. Any ideas or pointers to fix this issue would be highly appreciated, maybe I am missing some very basic configuration. Or maybe there is another simpler way instead of using a dispatcher module. Thank you! Regards, Shah Hussain
