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. Kind regards 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

Sipcapture module insert error

Hello, I’m not sure if this is the correct forum for this question but here goes… I’m facing an issue setting up a sipcapture server. I’m seeing several db errors in the logs: Mar 6 10:45:13 sipcapture /usr/local/sbin/kamailio[37872]: ERROR: db_mysql [km_dbase.c:123]: db_mysql_submit_query(): driver error on query: Data too long for column 'correlation_id' at row 1 I did a packet capture of the sql query and it appears that the value for the correlation_id is omitted. Interestingly its not all packets but maybe 60%. Do I have something misconfigured?

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

help with a new install
by David Dunlap 10 Mar '15

10 Mar '15

Hello, I am seeking help with a new test server. I have SIP messages coming from a working FreeSwitch and getting posted into the sip_capture table. Homer web service is responding allowing me to manage log on accounts and other database settings however I do not see any packets in the web gui. I used the install script from the web page and did not notice any errors as it worked. I sure would appreciate some help. The IRC channel was empty. Thanks David Dunlap [cid:D854C04A-3D89-4B99-AD05-D242790BFC94] 3105 N.

Transfer call between devices
by Phil Daws 10 Mar '15

10 Mar '15

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

Hello, I received INVITE with 3 Diversion headers. I try to make substitutions in the body of a first Diversion header field by using flag "f", command *subst_hf("Diversion", /sip:(.*)@/sip:$var(dU)@/", "f") ;* substitutes *all headers *Diversion instead of only first header, command *subst_hf("Diversion", /sip:(.*)@/sip:$var(dU)@/", "*l*") ;* substitutes only *last* Diversion header. Thanks for help, Julia.
