Hi, I am having issues with trying to use multiple lcr_ids so I can route to different groups. When I reload lcr it always only shows one group. I have copied the first group exactly and just changed the number but can't work out why it's not working. Any ideas? Thanks Keith

Exported params of USRLOC module
by aawaise 10 Apr '14

10 Apr '14

Hello, I am using kamailio-3.1 with siremis. I want to ask some questions about the exported params of usrloc module defined in the link given below. http://kamailio.org/docs/modules/3.1.x/modules_k/usrloc.html#id2997066 1. These exported params export value to whom ?? Other params or siremis location table ?? 2. If any export param is not defined in kamailio.cfg. Does its default value considered automatically or it is not used at all ?? 3. In siremis location table, I am not able to show my domain name of selected online user when I click on user. I want to do it. User's contact, received and other columns are filled but not domain name :( Shall I dig deep into usrloc module or I need to follow some other path to resolve this issue ??

Segfault when trying to send MESSAGE through websocket with jsSIP

I am currently trying to replace a pure-Asterisk implementation of SIP messaging through Websockets, with a Kamailio-4.1.2-based implementation.

cnxcc
by Kelvin Chua 09 Apr '14

09 Apr '14

i am trying to use cnxcc for the first time. kamctl kamcmd cnxcc.active_clients client_id:6,number_of_calls:1,concurrent_calls:0,type:1,max_amount:0.000000,consumed_amount:0.000000; i don't think this is correct, seems like the dialog is not disengaging after i hang up. i created dialogs alongside cnxcc just to compare, all dialogs were disengaged. is this an expected behavior? It's also weird that the max_amount is 0 while i checked that there is a value for credit being passed as an argument. Kelvin Chua

rfc: evapi architecture and message format
by Daniel-Constantin Mierla 09 Apr '14

09 Apr '14

Hello, (cross-posting because the results are impacting users) recently I added a new module named evapi: - http://www.kamailio.org/docs/modules/devel/modules/evapi.html The purpose is to able to send custom messages to applications that connect to kamailio via tcp on a special port (different than sip port) as well as receive messages and react on them. One of the first use case we look at is integration with cgrates for real time billing. For example: - send notification when a new call comes in and cgrates will return allow/reject - send notification when the call starts so cgrates can start billing - send notification when the call ends so cgrates will close bllling The module is now in quite good shape, sending and receiving messages. Sending is done from config file, in the future some modules might do it from inside. Received message is passed to config file via an event_route and variables. Now, the point of this discussion is to debate following points: 1) should there be a specific format used for this messages? The examples in the README use json. The module can encapsulate them in netstring format when sending over tcp to be easy to parse and read the message at once. This is optional, the message can be sent as it is 2) now messages are sent to all connected applications, should be there some subscription mechanism per event? If yes, then there has to be a way to specify the event, so point 1) might need a specific format 3) handle response - should be there a defined api that will say allow, reject, drop? I was thinking that the return could be some script for an embedded interpreter (e.g., Lua) that can be executed from config file. Or, alternative, manually scripted in the event route, so each user defines its own api 3) other suggestions for what should be discussed? Looking forward to opinions regarding these matters. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Kamailio IMS dnszone
by Andrea Meroni 09 Apr '14

09 Apr '14

Issue fixed: i just had to add the following line dns_try_naptr=yes to all the kamailio.cfg files of each of my IMS entity. I suggest to modify accordingly the config files in each of the examples (pcscf, icscf, scscf) in the master tree in order to make them properly working with the kamailio_ims_dnszone example Regards, Andrea

Dialog: Keep-alive issue:
by Vassilis Radis 08 Apr '14

08 Apr '14

Hello, I am trying to use the dialog module for dealing with some cases where clients do not send BYE messages correctly and just disappear. For this reason i use the ka_timer and ka_interval along with ka-dst and ka-src attributes. I am using the master branch. I have setup the following test: I have setup a sipp instance as a callee uas configured to discard OPTIONS messages. Kamailio serves as a proxy between this sipp instance and a VoIP device registered to kamailio. Kamailio is also configured to send every call to the sipp uas with stateful proxing and dialog support: CALLER ------> KAMAILIO -----> CALLEE (sipp / ignores OPTIONS msg) I have the following issue: 1. Dialog does send the OPTIONS messages to caller and callee, and as expected, only the caller responds (with a 200 OK response). But the dialog module never terminates the dialog as it should (because the callee never responds to the OPTIONS msg). Instead it keeps sending those OPTIONS for ever. It is like there is no timer entry in the timer list for those OPTIONS. I looked a bit in the source code and I am trying to find where a timeout for those keep alives is a)set and b)handled . I see that the dlg_timer_routine is called every second but after turning debugging on, i see that the only timer reported is the default timeout for the call which i ve set to 3600 secs in the module parameters. Any insight or advice? Thanks a lot.
