pkg memory leak when acc module cdr_enabled
by Juha Heinanen 10 Jan '23

10 Jan '23

In latest stable K release, we noticed pkg memory leak (pgk memory usage increases by each processed call). It turned out that the leak goes away if acc module cdr_enable is not enabled. Could be a bug in dialog or acc module. Any debug instructions if the bug is not obvious? -- Juha

TypeError exception in Kemi with python3
by Michel Pelletier 06 Jan '23

06 Jan '23

Hello, I am using Kemi with Python3. I am getting a TypeError exception when using the following: KSR.presence.handle_subscribe() 40(208) INFO: PY3 {SUBSCRIBE}: app_python3 [apy_kemi.c:1839]: sr_apy_kemi_exec_func(): alert - action KSR.presence.handle_subscribe(...) took too long [2004761 ms] (file:(null) func:(null) line:733) 40(208) ERROR: PY3 {SUBSCRIBE}: app_python3 [python_support.c:156]: python_handle_exception(): apy_exec: ksr_request_route((null)): Unhandled exception in the Python code: TypeError: expected bytes, str found The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/etc/kamailio/kamailio.py", line 152, in ksr_request_route if self.ksr_route_presence(msg) == -255: File "/etc/kamailio/kamailio.py", line 733, in ksr_route_presence KSR.presence.handle_subscribe() SystemError: <built-in function handle_subscribe> returned a result with an error set Using the following appears to be a good workaround, as it does not exhibit the issue at all: KSR.presence.handle_subscribe_uri(KSR.pv.get("$fu")) Cheers, Michel Pelletier

Call drop when reinvite is proceed
by nathan.castillo＠snapcom.fr 05 Jan '23

05 Jan '23

Hello all, I'm trying to figure out one problem on my Kamailio server. When kamailio receive a reinvite from the infra, I get the error message "477 - Unforunately error on sending to next hop" and the call drop. I don't understand why this message appears as the first invite is well answered and the call is going well. Any ideas how to resolve this issue ? Thanks in advance for your help. Regards, Nathan

Too many 200:OK sip responses
by Waqar 40 05 Jan '23

05 Jan '23

Dear All, For a normal call, Kamailio receives 200:OK sip response for the method invite only once but for some calls, it receives 200:OK too many times around 6 to 7. And I also do not receive BYE or any other packets for this kind of call. How can I detect such calls in Kamailio and cancel them? I am inserting data of the calls in the database when the call occurs and deleting it when BYE is received but for these calls as I don't receive BYE so I am unable to delete the record of such calls. Is there a way to detect such calls? Like How can I count if the number of 200:OK responses is more than one or anything like that? Regards Vicky

How to have Kamailio retry backends
by Unai Rodriguez 04 Jan '23

04 Jan '23

Dear List, We’re using Kamailio to load balance MRCP requests to multiple backend groups with a configuration as follows: # kamailio.cfg ... ... route[DISPATCH] { if($ua=="mrcp_backend_1") { if(!ds_select_dst("1", "4")) { send_reply("404", "No destination"); exit; } } if($ua=="mrcp_backend_2") { if(!ds_select_dst("2", "4")) { send_reply("404", "No destination"); exit; } } xlog("L_DBG", "--- SCRIPT: going to <$ru> via <$du>\n"); t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } ... ... # dispatcher.list 1 sip:mrcp01.server.int:8060;transport=tcp 1 sip:mrcp02.server.int:8060;transport=tcp 2 sip:mrcp03.server.int:8060;transport=tcp 2 sip:mrcp04.server.int:8060;transport=tcp With this configuration, Kamailio load balances the initial SIP INVITE among the MRCP servers. After the INVITE, the service communicates directly to the MRCP servers via SIP (for hanging up the call), MRCPv2 (for sending speech control messages), and RTP (for sending audio). We would like to implement a configurable number of retries, so that if a particular backend times out, Kamailio would retry X times to other backend(s). In short, something equivalent to HAProxy’s retries, but for Kamailio. This probably implies having Kamailio always as part of our communication (not just load balancing the initial SIP INVITE). I haven’t been able to find much information about this, could someone provide some pointers? Thank you so much With best wishes, Unai Rodriguez

Recover call in ringing state
by Devang Dhandhalya 04 Jan '23

04 Jan '23

Hello All I have below setup : SBC -> kamailio -> Media server(remote) -> web-client Call comes from sbc to kamilio and it relays to Remote server to end user, In Ringing state if remote server goes down then in kamailio there is any way to Recover that ringing call like we can generate new invite for other Remote server which is active state, for relaying call i am using dispatcher module.. I tried with tm.cancel RPC command but it works only if the remote server is running , when I crash the remote server at that time tm.cancel is not generating cancel to remote server. Please suggest if there is any other way to generate INVITE.

Localy generate BYE message from ims_charging
by masoud96＠mail.ru 03 Jan '23

03 Jan '23

Hello! I have a problem with writing the BYE message from the ACC module to the database, because the messages are generated locally by the ims_charging module at the end of the credit and the flag will not work. You can help catch such local messages and make a record in the database.
