But I want to Send AAR/AAA only after 200 ok. Below is the Sequence CER -------> <-------CEA REGISTER---> <-------401 REGISTER----> <----200 ok AAR ---------> <------AAA I using PCSCF as Diameter client and Seagull as a Diameter server. With changes in Kamailio.cfg Richard Good on Dec 17, 2014 Updated P-CSCF example with additional Rx_AAR params<https://github.com/kamailio/kamailio/commit/b450a769cff3b5c8ea0962299f6b087…> I am able to REGISTER but not able to send AAR/AAA after 200 ok.(Refer Attachment) Kindly let me know any other changes required in kamailio.cfg or seagull scenario.xml or some where else. and What changes.

Recommended configuration for TCP support
by Mickael Marrache 08 May '15

08 May '15

Hi, We sometimes get issues caused by truncated SDP bodies. Therefore, we are looking at using TCP instead of UDP. What is the recommended configuration when TCP is used? Currently, I only have the following: children=16 listen=udp:<ip>:5060 listen=tcp:<ip>:5060 disable_tcp=no tcp_connection_lifetime=605 (registration expiry is 600) Also, is there a difference with UDP regarding NAT handling? Thanks, Mickael

Timer Process versus Slow Timer Process
by Mack Hendricks 08 May '15

08 May '15

Hi All, I'm looking to have a better understanding of when to use the Timer process versus the "Slow Timer" Process. This is what I came up with, but please correct me: - The “*Timer*” process is used to handle core processing within Kamailio. Therefore, you don’t want to put long running logic into the routing handler - The “*Slow Timer*” process can be used for long running processes

is there any way to make deb packages for only 1 of the modules ?? currently it takes a long time to run "make deb" im simply trying to build and package db_cassandra ( need the package for my environment ) As a side note, is there any chance db_cassandra could be added to the kamailio deb packages ? -- Sincerely Jay

permissions module, regular expression matching Request URI
by Vik Killa 07 May '15

07 May '15

Hello, We would like to match specific calls based on two factors: 1. the source IP address 2. the Request URI I see in the permissions module, it is possible to match based on the Source IP + the From URI. We need two match both in order to return the appropriate 'tag' attribute from table. Would anyone know of a way to accomplish this? Also, I noticed that matching source IP + from uri, you cannot control which result is returned by permissions module based on regular expression. In other words if more than one match is made, permissions module seems to return the first result. Thank you and I look forward to your response. V

by Mickael Marrache 07 May '15

07 May '15

Hi, After restarting Kamailio, I got the following errors during the startup: kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:381]: db_mongodb_get_columns(): field [caller_sock] not found in result iterator kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:739]: db_mongodb_store_result(): failed to set the columns kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:918]: db_mongodb_query(): failed to store result kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:927]: db_mongodb_query(): failed to do the query kamailio[12614]: ERROR: dialog [dlg_db_handler.c:257]: select_entire_dialog_table(): Error while querying database What may be causing the issue?

TCP connection reset by peer
by Mickael Marrache 07 May '15

07 May '15

Hi, I sometimes see the following in the logs: kamailio[14433]: ERROR: <core> [tcp_read.c:271]: tcp_read_data(): error reading: Connection reset by peer (104) kamailio[14433]: ERROR: <core> [tcp_read.c:1296]: tcp_read_req(): ERROR: tcp_read_req: error reading It looks like Kamailio tries to read a request from a TCP socket but the connection has been reset (not properly ended) by the remote peer. Is it an error? Does it prevent Kamailio from working properly? If yes, what is the solution? Thanks, Mickael

RFC: Config files installation
by Daniel-Constantin Mierla 06 May '15

06 May '15

Hello, cross posting to get heads up of everyone that wants to join the discussion, however, do reply to sr-dev(a)lists.sip-router.org, being more related to development and project files structure. At this moment we install three kamailio configuration files: - kamailio.cfg - the default one to be used when starting kamailio - kamailio-basic.cfg - a more simple version of configuration - kamailio-advanced.cfg - a more complex version (equivalent of kamailio-oob.cfg in etc/ source tree) Somehow it was suggested that apart of kamailio.cfg, the other files belong more to the docs (shared) folder (where we put INSTALL, README, etc), because they are not actually used as configuration files by kamailio installation (one has to change either init.d script or copy over kamailio.cfg). Also, some are confused not knowing if they are used or not at runtime. Shall we relocate where those files are deployed by installation? Another point: we deploy the radius dictionary with the core. I think it should be deployed by a radius module and be part of radius modules package. The question is which module should deploy it? Is auth_radius fine for everyone? Alternative would be acc_radius. To complete the cleanup of etc/ folder in the source code, I think the sip-router*.cfg files should me moved to examples/, at quick look they are invalid, using paths to old ser modules, no longer available at this moment (therefore I guess nobody is using them). Opinions and other suggestions are very welcome!
