Choosing a Testing and Validation Tool
by Duarte Rocha 08 Mar '18

08 Mar '18

Hey I need to create several testing and validation processes for the deploy of an SBC and i would like to know your opinion on the best tools to use. I need to create an automated group of testing scenarios and validation of the packets sanity and SIP compliance. I also would like to validate the packets according to some parameters of mine (ex. All numbers in E164, etc). I'm looking at Star Trinity's SIP Tester right now but i'm not sure it can fulfill all my needs. I've also looked into … [View More]

Disable non-existent user warning
by Stefan Rüetschli 08 Mar '18

08 Mar '18

Hello sr-users! I'm using Kamailio 5.1.2. If I execute the command "serctl acl grant 1234 mygrant" I get a warning which I have to accept with "Y": Non-existent user '1234'. Still proceeding? [Y|N] Is it possible to deactivate this warning? I know why this warning is there (it's not a user, it's an alias), so I think I know what I'm doing ;-) Regards Stefan

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 … [View More]

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]: … [View More]

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"… [View More], "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 … [View More]

Not documented parameter server_id_filter inside usrloc module
by Konstantin Polyakov 05 Mar '18

05 Mar '18

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
