by Pranathi Venkatayogi 28 Apr '17

28 Apr '17

kamailio and siremis
by David Villasmil 27 Apr '17

27 Apr '17

Hello, Maybe this isn't the right place. Just installed SIREMIS (4.3.0) on a kamailio 5, everything works with the admin user, but when creating a SIP USER, after clicking on "Save" the page goes to http://1.2.3.4/siremis/system/user_detail/5 which just shows a blank page. Nevertheless, the user IS created and shows up on the "user management", but when the user tried to login, after clicking on "login", it shows a "processing login" and a pop-up comes up ( http://1.2.3.4/siremis/index.php/user/login) which just show a "1" here's the log: {code} '04/27/2017','20:25:22','DEBUG','DATAOBJ','Query Sql = SELECT T0.id, T0.username, T0.password, T0.enctype, T0.email, T0.status, T0.lastlogin, T0.lastlogout, T0.create_by, T0.create_time, T0.update_by, T0.update_time FROM user T0 WHERE T0.username='nocadmin' and status='1' LIMIT 1 BIND: ','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','Query Sql = SELECT T0.id, T0.username, T0.password, T0.enctype, T0.email, T0.status, T0.lastlogin, T0.lastlogout, T0.create_by, T0.create_time, T0.update_by, T0.update_time FROM user T0 WHERE T0.username='nocadmin' LIMIT 1 BIND: ','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','Query Sql = SELECT T0.id, T0.first_name, T0.last_name, T0.display_name, T0.company, T0.department, T0.position, T0.fast_index, T0.photo, T0.phone, T0.mobile, T0.fax, T0.zipcode, T0.province, T0.city, T0.street, T0.country, T0.email, T0.webpage, T0.qq, T0.icq, T0.skype, T0.yahoo, T0.misc, T0.type_id, T1.name, T0.sortorder, T0.user_id, T0.published, T0.default, T0.access, T0.params, T0.create_by, T0.create_time, T0.update_by, T0.update_time FROM contact T0 LEFT JOIN contact_type T1 ON T1.id = T0.type_id WHERE (T0.published=1 or T0.user_id='4') AND T0.user_id='4' ORDER BY T0.sortorder ASC, T0.id ASC LIMIT 1 BIND: ','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','Query Sql = SELECT T0.id, T0.user_id, T0.role_id, T1.name, T1.startpage FROM user_role T0 INNER JOIN role T1 ON T1.id = T0.role_id WHERE T0.user_id='4' BIND: ','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','Insert Sql = INSERT INTO event_log (user_id, ipaddr, event, message, comment, timestamp) VALUES (:_v1, :_v2, :_v3, :_v4, :_v5, :_v6); BIND: 4,6.7.8.9,LOGIN,MSG_LOGIN_SUCCESSFUL,a:2:{i:0;s:8:"nocadmin";i:1;s:13:"6.7.8.9";},2017-04-27 20:25:22','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','New record Id is 14','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','Query Sql = SELECT T0.id, T0.username, T0.password, T0.enctype, T0.email, T0.status, T0.lastlogin, T0.lastlogout, T0.create_by, T0.create_time, T0.update_by, T0.update_time FROM user T0 WHERE T0.username='nocadmin' LIMIT 1 BIND: ','n/a' '04/27/2017','20:25:22','DEBUG','DATAOBJ','Update Sql = UPDATE user SET lastlogin = :_v1, update_by = :_v2, update_time = :_v3 WHERE id='4'; BIND: 2017-04-27 20:25:22,4,2017-04-27 20:25:22','n/a' {code} nothing else is shown, nothing happens...

JANSSON module not working for multiple JSON objects
by vivek＠advaitamtech.com 27 Apr '17

27 Apr '17

Hi All, Am using JANSSON module to parse the JSON object I receive. I tried using JSON module of kamailio. Since its giving error in loading the module due to error"libjson-c.so.3: cannot open shared object file: No such file or directory", I went ahead to use JANSSON module. JANSSON module is parsing the single JSON object perfectly. But not parsing the multiple JSON objects. JSON object am trying to parse: $avp(result1)= "[{"origin":"125.16.231.74","Dest":"725.76.731.77"},{"origin":"225.26.231.24","Dest":"225.26.231.27"}]" JANSSON API used: jansson_get("origin", "$avp(result1)", "$var(origin)"); Any suggestions will be really helpful. Thanks, Vivek

SIGCHLD causes termination, but it appears that no child process has actually stopped.
by Cody Herzog 27 Apr '17

27 Apr '17

Hello. I'm running Kamailio 4.3.5 on Ubuntu Server 14.04. I just started using the app_python module together with the OpenTok Python SDK, described here: https://tokbox.com/developer/sdks/python/ My basic Python test script works fine, but when I add an import statement in the Python script to bring in a package from the OpenTok Python SDK, Kamailio terminates right after launch with the following log message: "terminating due to SIGCHLD" I was surprised to not find any extra log messages indicating which child process was causing the signal. I hacked the code in the handle_sigs() function in main.c.c to NOT terminate in response to SIGCHLD, and was surprised to see that my Python script was working fine, and was able to properly use the OpenTok Python SDK. I then started adding more debugging log statements and discovered that the call to waitpid() was returning 0, which apparently indicates that no child process has changed state. It's very strange, because it seems that SIGCHLD is being sent and handled, but waitpid() is indicating that no child process has changed state. I'm not sure if that is valid situation which needs to be handled. Perhaps SIGCHLD is sometimes sent for spurious or harmless reasons which should be ignored, and not result in total Kamailio termination. My current workaround is to NOT terminate when SIGCHLD is received and waitpid() indicates that no child process has changed state. In other words, I only terminate when the waitpid() while() loop has been entered at least once due to a return value greater than 0. Does that seem like a change that might make sense in the master branch going forward, or does it seem dangerous somehow? I'm not sure if this is helpful, but the waitid() system call (available since Linux 2.6.9) provides more precise control over which child state changes to wait for. http://manpages.ubuntu.com/manpages/trusty/man2/wait.2.html Thanks for any help.

Query with regard to http_client and http_async_client
by Ramachandran, Agalya (Contractor) 26 Apr '17

26 Apr '17

Hi Giacomo, I have few questions with regard to rest client in kamailio. 1) I see there are two modules in kamailio for rest client. http_client, http_async_client. I hope http_client does the http transfer in synchronous way. http_async_client does the http transfer in asynchronous manner. Correct me if am wrong here. 2) I want to achieve https transfers in async way, so choosing http_async_client. Is there a way that kamailio maintains persistent TCP connection pooling for http transfer. I see there is a "workers" parameter in http_async_client. By increasing this number does it result it more http request's handling? 3) Also, I have some questions regarding documentation for module http_async_client in 5.0 version. In the API exposure, it says "http_async_query(url, route_name)". But the example if I want to use POST, it says "http_async_query("http://example.com/test.php", "{'r_uri':'$rU', 'f_uri':'$fU'}", "HTTP_REPLY");" There is a parameter mismatch between the example and the actual function. If I try to use GET query, kamailio service is starting. But if I try to give the POST query with payload, kamailio service is not started. It says, sctp_core_destroy(): SCTP API not initialized. Also I have noticed that, functions like http_append_header(),http_set_method() are removed in 5.0 version, whereas we have this API's is 4.x versions. Is there some issue with the documentation for 5.0 ? Please let me the know the details for the above queries. Regards, Agalya

forwarding multiple times
by hdssdsdsdsfsdf hdssdsdsdsfsdf 26 Apr '17

26 Apr '17

Hi all, I'm trying to transmit a CANCEL sip message from one server to multiple other servers (using ds_select_domain and ds_next_domain). Ideally, I would simply use forward() multiple times. The problem is however, that this would apply the changes of forward() multiple times too, for example adding multiple via-headers. I tried to use forward() for the first transmission and then send() for the next ones, but it turns out send() uses the original message to send, and not the message as crafted by forward. As such, it seems I need exactly what's in the middle of these: Either a forward that operates on the original message, or a send that operates on the message as crafter by previous forward. Does anyone know how to achieve this? The only other solution I see is to manually write some forwarding routing, but it seems tedious to craft the via-headers and fix the domain to be forwarded to. Thanks and cheers,

How to eliminate Content-Length:0 from sl_send_reply
by Pranathi Venkatayogi 25 Apr '17

25 Apr '17

Hi, How do I eliminate Content-Length:0 from sip reply when using sl_send_reply? I wanted to generate 200 ok, with SDP payload. I appended headers like below. The packet seems ok except there is extra "Content-Length:0", which is causing problems. Any workarounds? The packet being generated is: Note the extra content-length: 0 at the end. SIP/2.0 200 OK Via: SIP/2.0/UDP 10.0.0.12:59404;rport=59404;branch=z9hG4bKPjb7d0391f8f7f479b812f6e5feadfa3c5;received=10.11.200.46 From: "cust1" <sip:cust1@devtranslation.sms-test.cyracom.com>;tag=afcffa277e2a43dc88fafc612f538864 To: <sip:spanish@devtranslation.sms-test.cyracom.com>;tag=37b119f34ca40c158c5b7306e1aa8d72.b73a Call-ID: 7f73e5d03e15425395fac930eae423bd CSeq: 31419 INVITE Content-Type: application/sdp Content-Length: 350 v=0 o=- 3688213899 3688213900 IN IP4 10.99.52.17 s=Blink 1.4.2 (Windows) t=0 0 m=message 2855 TCP/MSRP * c=IN IP4 10.99.52.17 a=path:msrps://10.99.52.17:2855/116701522521345;tcp a=accept-types:message/cpim text/* image/* application/im-iscomposing+xml a=accept-wrapped-types:text/* image/* application/im-iscomposing+xml a=setup:active Content-Length: 0 Code in config is: append_to_reply("Content-Type: application/sdp\r\n"); append_to_reply("Content-Length: 350\r\n"); append_to_reply("\r\n"); append_to_reply("v=0\r\n"); append_to_reply("o=- 3688213899 3688213900 IN IP4 MY_IP_ADDR\r\n"); append_to_reply("s=Blink 1.4.2 (Windows)\r\n"); append_to_reply("t=0 0\r\n"); append_to_reply("m=message 2855 TCP/MSRP *\r\n"); append_to_reply("c=IN IP4 MY_IP_ADDR\r\n"); append_to_reply("a=path:msrps://MY_IP_ADDR:2855/$var(ssessid);tcp\r\n"); append_to_reply("a=accept-types:message/cpim text/* image/* application/im-iscomposing+xml\r\n"); append_to_reply("a=accept-wrapped-types:text/* image/* application/im-iscomposing+xml\r\n"); append_to_reply("a=setup:active\r\n"); sl_send_reply("200", "OK"); Thanks, Pranathi Venkatayogi System Developer II (520) 745-9447 x4466 www.cyracom.com<http://www.cyracom.com/> Join us: [cid:image001.gif@01D1C9C9.C4E8B6D0] <https://www.facebook.com/pages/CyraCom-LLC/134704783312720> [cid:image002.gif@01D1C9C9.C4E8B6D0] <https://twitter.com/cyracom> [cid:image003.gif@01D1C9C9.C4E8B6D0] <http://www.linkedin.com/company/cyracom> [cid:image004.gif@01D1C9C9.C4E8B6D0] <http://www.cyracom.com/blog/> [cid:image005.png@01D1C9C9.C4E8B6D0] DISCLAIMER: This e-mail and any attached content may contain confidential or privileged material delivered for the sole use of the intended recipient(s).
