OT: results investigating why kamailio.org was not responding recently
by Daniel-Constantin Mierla 11 Mar '15

11 Mar '15

Hello, as some noticed and informed privately or on mailing list, several days ago kamailio.org was not accessible. It was caused by apache getting stuck on connecting to a remote host due to the pingback feature of wordpress. All the other services were fine. Listing running processes showed a large number of apache instances connecting to an address like 23.x.y.204 and being stuck in that state. Fetching the page from that address with wget resulted in some html with embedded obfuscated javascript. I couldn't find a reason why apache was not closing the connection, although there are some timeouts in configs. Also, as I expect apache/php/wordpress don't run javascript, the issue should be somewhere at the http layer. At some point apache reached the max number of threads and didn't serve other requests. The solution was to disable the pingbacks using a plugin for wordpress named: Disable XML-RPC Pingback . All seems ok for the last days. I posted here just in case it will be useful for someone else, but also to get hints on other tweaks that we should to do wordpress to prevent similar situation, if anyone can share from his/her experience.

Calling ims charging function in route_failure
by Shane Harrison 11 Mar '15

11 Mar '15

Hi all, What I want to do ~~~~~~~~~~~~~~ If a call to a SIP AoR fails then try the PSTN number associated with the AoR by routing the request to a PSTN gateway. Calls to a PSTN gateway need to be charged so need to call the Ro_CCR function in ims_charging module. How I tried to do it ~~~~~~~~~~~~~~ In the failure_route[MANAGE_FAILURE] block I call the Ro_CCR() Result was ~~~~~~~~ Kamailio fails to parse config file. yyparse(): misused command Ro_CCR yyerror_at(): parse error in config file //etc/kamailio/kamailio.cfg, line 1162, column 91: Command cannot be used in the block So two questions: 1) What constraints are there for calling functions in the failure_route blocks i.e. how does parser decide what can be called and what can't 2) Any thoughts of how I can do effectively a late charging decision Cheers and thanks in advance Shane Shane Harrison Senior Software Engineer Imagination Technologies NZ Limited Level 2 1 Market Grove Lower Hutt, 5010 New Zealand PO Box 30-449 Lower Hutt, 5040 New Zealand Phone: +64 4 890-3681 ext 3361

ims_charging module
by Shane Harrison 10 Mar '15

10 Mar '15

Hi all ims'ers I have modified the ims_charging module to cope with the CCA return code of "CREDIT CONTROL NOT APPLICABLE". This means the call is not a chargeable call and the charging module now returns a unique return code for this. Currently there are two scenarios handled: 1) CCA grants the credit required for the call --> route the INVITE and then automatically new CCR requests are made for further credit as the call progresses 2) CCA doesn't grant the credit ---> send an error response back to INVITE originator - I assume this will clear all dialogs and no further credit requests are made. The question I have, is how do I cope with this unique return code so that I can continue to route the call but not make any more CCR requests to the credit control server? As I am not sure how the ims_charging module continues to generate CCR requests, it is difficult for me to understand how to essentially clear the whole CCR session without clearing the call.

SIP 500 on WSS connection lookup failure
by Armen Babikyan 10 Mar '15

10 Mar '15

Hello, I am setting up this scenario using Kamailio 4.2.2: [UA] <-> [kamailio1] <-> [kamailio2] <-> [other stuff] UA connects to kamailio1 using SIP/WSS, kamailio1 proxies request along to kamailio2. Note that my intent here is to have kamailio2 provide the registrar functionality. The kamailio2 (or something behind it) can also initiate transactions to UA, like OPTIONS, for example. I'm having an issue though: when the websocket connection between kamailio1 and UA dies, transaction requests from kamailio2 show up to kamailio1, and I get errors in kamailio1's logs because the WSS connection is gone. I get messages as follows (debug=2): Mar 6 00:17:33 kamailio1 /usr/local/sbin/kamailio[5653]: WARNING: <core> [msg_translator.c:2778]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found Mar 6 00:17:33 kamailio1 /usr/local/sbin/kamailio[5653]: ERROR: <core> [msg_translator.c:1996]: build_req_buf_from_sip_req(): could not create Via header Mar 6 00:17:33 kamailio1 /usr/local/sbin/kamailio[5653]: ERROR: tm [t_fwd.c:527]: prepare_new_uac(): could not build request Mar 6 00:17:33 kamailio1 /usr/local/sbin/kamailio[5653]: ERROR: tm [t_fwd.c:1777]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches At debug=4, I get the output here: http://pastebin.com/d3RumekG In a running tshark, I see kamailio1 responding to kamailio2 with a "SIP/2.0 500 No error (2/TM)". It appears to me that this is happening before t_relay() even returns. Is there a way to prevent the SIP 500 from being sent back to the client? I am calling t_on_branch_failure("kam2bf") and t_on_failure("kam2f"), with each of those handlers (event_route[tm:branch-failure:kam2bf] and failure_route[kam2f]) written to print a log message, but it appears that neither of those handlers are being called. I tried installing these handlers independently to no avail. I also tried registering a t_on_reply() handler, thinking it was an internally-generated SIP response that might make it through my handler on its way out to kam2, but that is also not getting invoked. I want to return a 404 or something similar instead of having a 500 auto-returned for me. Related to this, is there a way to query kamailio's in-memory client connectivity data structure for the connectivity status of a client? Or is this something best done by keeping track of every client myself using (e.g.) localcache? Any pointers are appreciated. Thanks! Armen

Hello: wish to ask how one may configure Kamailio so that if a user has a number of devices registered eg. deskphone, soft client on tablet, and soft client on cellphone when a call is originated or received how it can be passed between devices. Is it as simple as configuring a blind transfer ? Thanks for any help. Phil

Hi, I'm continuously seeing the following WARNING in my logs: WARNING: db_mongodb [mongodb_dbase.c:454]: db_mongodb_get_columns(): unhandled data type column (instance) type id (10), use DB1_STRING as default It looks like the WARNING appears when data is fetched from the location collection.

Regd. Kamailio GPL
by Shankar 10 Mar '15

10 Mar '15

Hello, We are exploring kamailio source for use in our VOIP solution. This is the first time we are looking at open source. We have few doubts in using kamailio for providing our VOIP service. Under GPL any customization (customization mainly with respect to interacting with our proprietary applications e.g. Billing server) we do to kamailio also has to be provided to the end user. Our doubt is whether we can procure commercial rights to our customised code? Kindly clarify on this. Best Regards, Shankar

Dialog order of operations
by Alex Balashov 10 Mar '15

10 Mar '15

Hi, The dialog module documentation remains unclear about the order of operations with regard to when to call dlg_manage() or set the transaction flag. My impression is that dlg_manage() only registered TM callbacks, so it doesn't matter when you call it, as long as it's before t_relay(). However, the documentation neither confirms nor denies this. So, this raises the questions: 1) Is this okay? set_dlg_profile("caller", "$fU"); dlg_manage(); ... t_relay(); Or do I need to do this? dlg_manage(); set_dlg_profile("caller", "$fU"); ... t_relay(); 2) What about setting dialog-persistent variables? Is this okay? $dlg_var(account_id) = 49555; dlg_manage(); If so, where does the variable go if I never call dlg_manage() because the call is aborted beforehand, e.g. $dlg_var(account_id) = 49555; sl_send_reply("403", "Forbidden"); exit; dlg_manage(); ... t_relay(); 3) Any other gotchas or caveats in relation to the order of operations? I suppose my preference would be to set the dialog profiles in various places throughout call processing and call dlg_manage() at the very end, right before t_relay(). Is this acceptable?

Enable SNMP causes issue when forking exec_avp request
by Daniel Goepp 09 Mar '15

09 Mar '15

I have an issue that from what I can tell is related to forking. My configuration works just fine, and makes a request out to execute curl to hit an external API: $var(my_query) = "curl -m 2 -s http://x.x.x.x/service/method?fromAddr=" + $var(fu) + "\&toAddr=" + $var(tu); Normally this gives us back a nice JSON response, no problems. All I do is enable snmpstats module, and it fails. Mar 5 16:51:30 server-name /usr/sbin/kamailio[1051]: ERROR: exec [exec.c:291]: exec_avp(): cmd curl -m 2 -s http://x.x.x.x/service/method?fromAddr=me@mydomain.com\&toAddr=someone@mydo… failed. exit_status=-1, errno=10: No child processes I have edited this for security reasons of course. If I disable SNMP, the problem goes away. Thoughts?

rtpproxy failed to load

kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour I found this guide for an older version of Kamailio, but there seems to be some issues when trying to use it on the latest stable version. When I try to start Kamailio i get this : [....] 0(17153) INFO: tls [tls_init.c:399]: init_tls_compression(): tls: init_tls: disabling compression... 0(17153) ERROR: <core> [cfg.y:3286]: yyparse(): cfg. parser: failed to find command force_rtp_proxy (params 0) 0(17153) : <core> [cfg.y:3426]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 729, column 19: unknown command, missing loadmodule? 0(17153) ERROR: <core> [cfg.y:3286]: yyparse(): cfg. parser: failed to find command force_rtp_proxy (params 0) 0(17153) : <core> [cfg.y:3426]: yyerror_at(): parse error in config fil[FAILc/kamailio/kamailio.cfg, line 806, column 19: unknown command, missing loadmodule? ERROR: bad config file (2 errors) ... It seems it cannot load the rtpproxy module or that force_rtp_proxy command does not exist. For Debian the modules are located in /usr/lib/x86_64-linux-gnu/kamailio/modules/ and it was found there, seems to be loaded in the config file (line 5 and 235). According to the rtpproxy doc the module has this command. Does anyone have an idea what could be the issue ? I am planning to update this guide for the current version once I fixed all the issues. The most easy issues are the db/usernames/password and the path to the modules. -- Med venlig hilsen Tom Braarup Cuykens plusTEL.dk

lua_run seems to be working in asynchronous way
by José Seabra 09 Mar '15

09 Mar '15

Hi there, I'm using kamailio version 4.2.2 to a short time, and I'm using lua scripts to build some avps with information needed to make calls(lua functions uses redis as source data to build avp data.), what i have noticed today making some tests is that when i make a call my lua function: if(!lua_run("get_prefs","$fU","$fd")) { xdbg("SCRIPT: failed to execute lua function!\n"); } kamailio gets the avp's after send the invite to the destine,(the invite will fail because kamailio needs avp information). it seems that kamailio calls the lua_run in asynchronous way, i never noticed that before in old version. is that a normal behavior or it is an issue in this version? Best Regards -- Cumprimentos José Seabra

For REGISTER, you need to add the Path header (see path module), otherwise the OPTIONS and INVITE sent out to the phone are not going via Kamailio. You have to check the version of your Asterisk to be one that supports Path.

Group call advice: remove calling branch after alias_db_lookup/lookup_branches
by Anthony Messina 08 Mar '15

08 Mar '15

In terms of implementing "group" calling via the append_branch feature of both alias_db_lookup followed by lookup_branches, I'm looking for a reliable way to ensure that if the caller happens to be a member of the group (list of branches), the branch that's created to the original caller is dropped. Originally, I was thinking of comparing $rU and $fU in branch_route, but this would limit the ability for one contact of an AOR to call another contact of the same AOR. Can anyone offer an example of an efficient method to accomplish this? -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E
