Re: [SR-Users] Kamailio KeepAlived HA acc_cdrs table record
by Henning Westerholt 20 Jul '21

Hello, I have not tested it, but the dialog database will probably only help in a restart scenario with regarding to dialogs, at least with a standard cfg. Regarding the example below, this would mean starting the primary Kamailio again, then the cdrs should be generated during the hangup from the primary. You can test also to restart the secondary Kamailio, it should then also read the dialogs from the replicated table and generate cdrs at hangup.

I just looked briefly to the code; others might have more details. But I think this is because the acc module do not register to a callback function for dialog loading on startup for the DMQ replication. This is done for DB loading, but seems to be not implemented yet for DMQ synchronisation. You could open a feature request on our github tracker for this.

Kamailio KeepAlived HA acc_cdrs table record

Keepalived pass the Virtual IP to the secondary Kamailio and audio still work because I'm using a remote RTPENGINE server for both Kamailio. The problem is when the call end. On the acc table i can see INVITE and BYE entries but on the acc_cdrs table nothing. Second problem the dialog still present on the table dialog in a Primary/Primary replication.

Kamailio python_exec getting randomly TypeError
by Voip support 19 Jul '21

19 Jul '21

Dear Kamailio users, I am trying to use a python script using the module app_python3 to do some billing calculations. The only argument i want to pass to the python script is duration which i calculate in event_route[dialog:start] { $dlg_var('call_start') = $TS; event_route[dialog:end] { $var('v_duration') = $TS - $dlg_var('call_start'); So my $var('v_duration') has the duration of the call in seconds. Then i execute from my kamailio.cfg: python_exec("calculateCost","$var('v_duration')"); The script works randomly - sometimes all is good and sometimes it throw error : app_python3 [python_support.c:156]: python_handle_exception(): apy_exec: calculateCost(4): Unhandled exception in the Python code: TypeError: an integer is required (got type NoneType) The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/etc/kamailio/kamailio-python.py", line 282, in calculateCost duration = int(duration) It looks like the kamailio log show calculateCost(4) so argument 4 is passed to python function but once it executes it appear like there is no string/integer but NoneType argument. I cannot figure this out why this randomly happens - maybe it's an app_python3 module issue? Looking to hear back from you! BR, Tom

Active Profile for sipreply in SEMS
by Mojtaba 17 Jul '21

17 Jul '21

Hello, Does anybody know how i could change white filter in siprelpy in sems? In Kamailio, I got "200 OK" from UE, then add a new header (SBC: mt-reply) and send it to sems server. The sems server remove it: [#7f410fbfb700/4560] [inplaceHeaderFilter, HeaderFilter.cpp:226] DEBUG: erasing header 'sbc' by whitelist I really don't want to remove it. Actually if I knew how i active profile for sip replying in sems, I would be able to solve this. Thanks with regards. -- --Mojtaba Esfandiari.S

Hello guys, do you know if it’s possible for a kemi script to know if a name is defined (with #!define) in kamailio.cfg? It would be useful to modify kemi script logic depending on feature/module presence. Thanks in advance for your help.

rtpengine play_media

15 Jul '21

Greetings. I'm trying to set up annoncement playback for both parts of the call. I have to play the file after the connection is established. Stop_media (all) must be executed before playing It turns out the construction: .... block_media ("all"); play_media ("all file = / etc / kamailio / sounds / mg1.wav"); Can't find a way to do unblock_media ("all"); after the file has finished playing. There are no sip messages in this process. The call has already been established.

DMQ node list
by Aidar Kamalov 14 Jul '21

14 Jul '21

Hello, I have a kamailio cluster with two nodes kamailio-1.local: 10.101.2.119 kamailio-2.local: 10.101.2.247 with dmq configs: kamailio-1: modparam("dmq", "server_address", "sip:MY_IP4_ADDR:5060") modparam("dmq", "notification_address", "kamailio-2.local:5060") kamailio-2: modparam("dmq", "server_address", "sip:MY_IP4_ADDR:5060") modparam("dmq", "notification_address", "kamailio-1.local:5060") All works fine, but kamcmd dmq.list_nodes on kamailio-1.local show me: { host: 10.101.2.247 port: 5060 resolved_ip: 10.101.2.247 status: active last_notification: 0 local: 0 } { host: kamailio-1.local port: 5060 resolved_ip: 10.101.2.119 status: active last_notification: 0 local: 0 } { host: kamailio-2.local port: 5060 resolved_ip: 10.101.2.247 status: active last_notification: 0 local: 0 } { host: 10.101.2.119 port: 5060 resolved_ip: 10.101.2.119 status: active last_notification: 0 local: 1 } and kamailio-2.local show me: { host: kamailio-2.local port: 5060 resolved_ip: 10.101.2.247 status: active last_notification: 0 local: 0 } { host: 10.101.2.119 port: 5060 resolved_ip: 10.101.2.119 status: active last_notification: 0 local: 0 } { host: kamailio-1.local port: 5060 resolved_ip: 10.101.2.119 status: active last_notification: 0 local: 0 } { host: 10.101.2.247 port: 5060 resolved_ip: 10.101.2.247 status: active last_notification: 0 local: 1 } So there are only two hosts in the cluster, but there are 4 records in dmq.list_nodes. Also in sip trace I can see that kamailio send DMQ messages to itself too (because it ip marked as local: 0 I think). Is it ok? Is it normal behavior? What should I do to fix it? Should multi_notify and DNS name with 2 A records fix it (and why?)? -- Aydar A. Kamalov

Re: [SR-Users] Subscriber Management using JSONRPC over HTTP
by Surabhi Garg 14 Jul '21

14 Jul '21

Hi Alex, By subscriber management I mean, auth_db module which actually works on subscriber table to add or alter sip account for authentications. Auth_db Module (kamailio.org)<https://kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.f.auth…> So, similar like usrloc module which you mentioned having JSONRPC commands to alter Location table. I am looking for JSONRPC Command for subscriber module as well. As far as my understanding, currently there is no JSONRPC command available for subscriber table. So, if this is currently a known not offered feature / limitation shall we raise it as feature request if others also agree to its usefulness. What I'm seeking is more of an acknowledgment that this feature doesn't exist & have it's benefit. As I can see other community members either ends up directly interacting with DB for subscriber table provisioning. Maybe I can contribute on this too.

DMQ_USRLOC module and calls
by Social Boh 13 Jul '21

13 Jul '21

Hello, I'm testing DMQ_USRLOC modulo between two Kamailio servers (A) and (B) The two servers share the same domain and using Amazon Route53 to distributes 50% requests each Server. The problem is when I try to make a call from user A (registered on kamailio A) and the user B (registered on Kamailio B). The call follow this flow: User A --> KamailioA --> UserB go directly to userB because KamailioA know, via DMQ_USRLOC IP and port of UserB. With some Softphone the call work with audio without problem; with other Softphone USERB never answer the INVITE sends from Kamailio. Is it possible use this flow? USER A --> KamailioA --> KamailioB --> User B to resolve this kind of problem or is there other available option? Thank you -- --- I'm SoCIaL, MayBe
