consume_credentials question
by Aymeric Moizard 07 Mar '18

07 Mar '18

Hi list! I'm trying to remove Proxy-Authorization dedicated to local subscriber without -and not the other ones dedicated to other server- I realized that "consume_credentials" doesn't work because it requires that a call to "www_authorize, proxy_authorize, www_authenticate or proxy_authenticate" has been made before. I have a use-case where this isn't called. I don't want to use such code: if (is_present_hf("Proxy-Authorization")) { remove_hf("Proxy-Authorization"); } Because this may remove a "Proxy-Authorization" for another service. I have seen this: has_credentials but it doesn't help to know which header is the one containing the header... Any good way to find the header and index? And then remove it with remove _hf_value2? Regards Aymeric -- Antisip - http://www.antisip.com

SIP RFC behaviour for 180/200 to_tag mismatch
by Mititelu Stefan 07 Mar '18

07 Mar '18

Hi people, I am trying to search for the RFC behavior in case of 180/200 to tag mismatch of an INVITE. From my readings so far, I'm not 100% convinced of the correct behavior. However, there may be a scenario, where this might be plausible: 1. parallel forked two calls 2. 180 ringing comes for first one, but not for second one(various reasons) 3. 200 ok comes for second one Any opinions about this? Do you have some references that will make this 100% clear? Thank you, Stefan

sqlops module error
by Fabian Borot 06 Mar '18

06 Mar '18

I am using the sqlops module with odbc to INSERT,UPDATE only and as the documentation says I can omit result parameter in "sql_query". However I always see these ERRORS when processing the call: This is an example of a query: sql_query("c04", "insert into SIPInfo302CDR (SIPCallID,SessionID) values('$ci',$var(SessionID))"); And these are the error lines in the log: ERROR: db_unixodbc [res.c:60]: db_unixodbc_get_columns(): no columns returned from the query ERROR: db_unixodbc [res.c:261]: db_unixodbc_convert_result(): getting column names failed ERROR: db_unixodbc [dbase.c:216]: db_unixodbc_store_result(): failed to convert result ERROR: <core> [db_query.c:188]: db_do_raw_query(): error while storing result ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query [insert into SIPInfo302CDR (SIPCa] I have also tried using the parameter like shown below but the ERROR events happen anyways. sql_query("c04", "insert into SIPInfo302CDR (SIPCallID,SessionID) values('$ci',$var(SessionID))", "ra"); sql_result_free("ra"); Even though the errors line show up and say that " cannot do the query .." the query does work and the records are inserted/updated accordingly. I tried using the "sql_query_async" function that does not need the result parameter but I can't use it with unixODBC, I see these lines in the log when trying to use it: "the db driver module doesn't support async query" and the record is not inserted/updated. I also added the "async_workers" core parameter as well just in case. I also tried declaring them in the module sqlops initialization section even though in my case there is no need: "modparam("sqlops", "sqlres", "ra")" but the errors show up anyways. When I test with SEELCT query the result parameter can be used, I can count rows etc. But I am only doing INSERT/UPDATE. Am I am missing something here or this is something that can be safely used like that and I just need to ignore them. I am using " Kamailio (OpenSER) SIP Server v5.0" Thank you Fabian

Re: [SR-Users] cnxcc module - make auth for redis connection
by Donat Zenichev 06 Mar '18

06 Mar '18

Hi Daniel, first of all thanks for your attention. Perhaps I missed something. I read documentation about cnxcc and ndb_redis again, but I haven't found information that can help me with my goal. ndb_redis is separate module that implements connections to redis databases (and also is able to perform authentication), has it's own functions like redis_cmd() to interact directly with redis. But cnxcc stores real-time amounts in redis hash keys using it's own parameter - modparam("cnxcc", "redis", "addr=127.0.0.1;port=6379;db=1") And I can't see possibility to use ndb_redis to perform authentication for cnxcc module, correct me if I'm wrong. Do you offer me to read ndb_redis code sources to use them to edit cnxcc code sources? Thanks in advance for your advice. 2018-03-01 9:28 GMT+02:00 Donat Zenichev <donat.zenichev(a)gmail.com>: > Hi Daniel, first of all thanks for your attention. > > Perhaps I missed something.

Setup timeout for in function jsonrpc_request
by Marco Capetta 06 Mar '18

06 Mar '18

Hi All, I'm currently in the process of upgrading a kamailio instance from 4.4.6 to 5.1.2. Since"janssonrpc-c" has been renamed in "jsonrpcc" I have to adapt my configuration. In version 4.4.6, the function "janssonrpc_request" allowed me to setup a specific timeout for the request. Is it possible to do the same in version 5.1.2 with the function "jsonrpc_request"? Because the documentation doesn't mention it. Thank you Best regards Marco

Re: [SR-Users] Not documented parameter server_id_filter inside usrloc module
by Konstantin Polyakov 05 Mar '18

05 Mar '18

Victor, We are going to use this parameter, but we found that cleanup process should use such filter too. Otherwise different instances of proxy delete records of each other and it leads to the problems when db_mode 1 or 2 (cached) is used. Soon I am going to propose a pull request with filter in cleanup procedure. Could you tell me please, if it is necessary to add a new parameter for cleanup process or I can use this server_id_filter? Is there some case when we need to use this filter on startup but we don't it during cleanup? Thank you. Best regards, Konstantin

Hello everybody, Could somebody clarify why server_id_filter parameter is not listed in the usrloc module article? It is not ready for usage? Or it was forgotten to be added into description? Thank you Best regrads Konstantin

Invoking RPC commands over HTTP
by Ben Hood 05 Mar '18

05 Mar '18

Hi, What is the idiomatic way to call an RPC from a remote HTTP client in the 5.1.x series? I'd like to invoke mtree.reload from a remote HTTP client. My goal is to avoid a dependency on kamcmd on the remote client system - it would be nice to be able to issue a HTTP RPC which could be implemented in any environment. Or should I be looking to implement a BINRPC client on the remote system? TIA, Ben

Kamailio iOS Push Notifications
by Amine Mensori 04 Mar '18

04 Mar '18

Hello, We need help implementing push notifications within Kamailio. I have found a module relating to this: https://github.com/tvntsr/push <https://github.com/tvntsr/push> However, the developer did not provide any examples of the cfg file, only parts of certain functions. We need some help implementing the functions in our config file or a full example of another method to get push notifications to work when the application is closed on the device. Please note we are not very proficient in C programming so a clear example would help a lot. Many Thanks, Amine
