rtpengine use of udp
by Juha Heinanen 05 Dec '14

05 Dec '14

what has been the motivation that rtpengine control protocol is using udp instead of tcp or ssl? we have noticed that reply to delete containing stats is too large for a single udp packet over ethernet and causes udp fragmentation and fragmentation needed requests. -- juha

Registrar path support on lookup
by Ben Langfeld 04 Dec '14

04 Dec '14

I'm facing a problem which I believe may be a bug in the registrar module's lookup. When a registration comes with multiple Path headers, these are recorded in the location table as comma separated. When the lookup is performed and these are used to construct the Route header(s) on an INVITE, this comma-separated list is not split into multiple Route headers, but instead included verbatim in a single header. Here comes my theory for how this breaks my scenario: When the INVITE then reaches the first hop (first Path header, also Kamailio), relay() sees that the Route header is itself and/or sees that there is only one Route header. The observed result is that the first hop then sends the INVITE directly to the Contact, instead of via the second hop. An example of the situation I'm facing is shown in https://gist.github.com/benlangfeld/b374a0ce0bdb6bdc35e7. Is there a particular reason the combined path is not split on lookup? Is this a bug / oversight? Am I crazy? Thanks! Ben

Re: [SR-Users] Not getting the final response after ringing
by Rizwan Khan 04 Dec '14

04 Dec '14

I am not sure if its the issue on my client end as CSIPSImple is not sendin the PRACK that is expected by the server or the rtp ports are not opened. I guess the ports are opened as I can hear two way voice. But the following issues remain: 1. I cannot receive a call on the SIP number 2. I dont get an indication on the caller (thru CSIPSimple) that a call has started as in it doesnt start the call timer 3. The call disconnects with an error after some time ..INternal Server Error.

Kamailio Failed to Query the Asterisk DB to Authenticate Registration Requests.
by Mahmoud Ramadan Ali 04 Dec '14

04 Dec '14

Hi Dears, I'm trying to configure Kamailio as SBC in multi home mode for Asterisk by authenticating the inbound SIP registration requests,i'm following this tutorial http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb to achieve this goal. i have modified the necessary changes like the Asterisk DB URL and the SIP table name and Username and password column and verified the Mysql connection. My topology like this Asterisk (192.168.100.10) <----Internal:192.168.100.1---->Kamailio<---External:192.168.50.1-----> SIP Phone (192.168.50.2) But when trying to register a SIP phone Kamailio generates these error messages Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Unknown column 'secret' in 'field list' Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: auth_db [authorize.c:175]: get_ha1(): failed to query database The Auth_DB Params in the configuration file is as follows. # ----- auth_db params ----- #!ifdef WITH_AUTH modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "load_credentials", "") #!ifdef WITH_ASTERISK modparam("auth_db", "user_column", "account") modparam("auth_db", "password_column", "secret") modparam("auth_db", "db_url", DBASTURL) modparam("auth_db", "version_table", 0) #!else modparam("auth_db", "db_url", DBURL) modparam("auth_db", "password_column", "password") modparam("auth_db", "use_domain", MULTIDOMAIN) #!endif I tried also to give the Auth_DB module all the paramaters like this but still receiving the same error !

Re: [SR-Users] Evapi reply processing
by DanB 04 Dec '14

Thanks Daniel, This was exactly what I was looking for. I have also reviewed again your "Asynchronous Processing in Kamailio Configuration File" presentation from Kamailio World 2014 and it provided me an incredible amount of digested information regarding async processing(especially the part with push notification). Will follow that approach, and yes, it is a brilliant idea to pass the transaction indentifiers to CGR and process them in evapi reply route, so no more dependency on htable needed. Cheers, DanB

Refreshing the Kamailio logo
by Daniel-Constantin Mierla 04 Dec '14

04 Dec '14

Hello, I was considering to discuss the state of Kamailio project logo for a while. The current state is ambiguous, to say at least - various logos in different places. When OpenSER was renamed in Kamailio we were trying to get something new, but due to the 'forks and dark waters' at that time, this process was never completing, meanwhile using an adaptation of old openser logo. However, there are no high resolution or other variants suitable for using in particular conditions (e.g., black and white, big posters). First, a question that we should decide on: shall we aim for a new logo or try to get someone to make proper graphics from the current shape? (for reference, the logo from http://www.kamailio.org/wp-images/kamailio-rock-logo.jpg). I would prefer to go for a new logo, but I admit that this process can become complex, a mater of tastes, not something we can decide on technical aspects. Therefore, if it ends up in something that doesn't seem to have the acceptance of major contributors (with coding, advertising/promoting, ...) to the project, then we stick with current for a while. My preference is based on the fact that Kamailio evolved over the time, has its own identity, so a fresh look of the logo would reflect that better. I am listing here the options, that people can express preference on: A) New logo A1) variant based on Kamailio World logo (used by twitter kamailioproject account and on some materials at various events). It was a backup variant so far as we had high resolution graphics that could be adapted to get a good image for big posters. Can be seen at: - http://www.kamailio.org/pub/kamailio-logos/variants/kamailio-from-world-log… - http://www.fredposner.com/1471/kamailio-at-astricon-2013/ A2) use a professional service for that. Kamailio World logo was made with 99designs.com service, which is quite good considering there will be many submissions to choose between, options can be visible by everyone. There might be other similar services, this is one I have experience with and worked fine in the past -- anyhow, it has to be something that all management and solution can be done online. Asipto can sponsor at least the bronze package if 99designs is going to be used, maybe others want to participate with extra funds to get a better package. A3) leverage on community, in case some companies have internal designers or some of you have such skills or friends. Perhaps this has the highest risk on escalating, given that is going to be some direct involvement in proposals and selection. B) Old logo B1) get someone to produce high resolution graphics from existing logo No matter what variant, who will do the work or financial contribution, will get credits via our web site. However, all the rights of the resulting logo will belong to the Kamailio project. To conclude, the order of my preferences: A2, A1, A3, B1 Looking forward to feedback from many of you! Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Evapi reply processing
by DanB 04 Dec '14

04 Dec '14

Hey Guys, We are in the process of implementing prepaid control using CGRateS engine and for that we will be using evapi module (thanks Daniel again for that). I was wondering if you can advice us whether the path we are taking is the correct one. On INVITE, we will initiate a MaxCallTimeout (sort of call auth) to CGRateS via evapi. Once request sent, we should "park" the request somehow (right now we are considering sleep in the process via usleep and recheck for the answer every 5-10 milliseconds). Answer should be shared via htable. Could you recommend us a better approach? On reply, the answer processed in event route evapi:message-received should set in htable a key of combination callid:fromtag with the maximum call duration or auth reject if not enough balance. This key should be processed by the sleeping process on wakeup. What do u think, is there a better way to approach the 2 ways communication? Thanks in advance for any kind of tip! DanB

Kamailio TCP Proxy
by Andrew Mason 04 Dec '14

04 Dec '14

Hi All, I am testing SIP messages through the proxy from one client to another and the sender specifies TCP as the transport but Kamailio seems to overwrite this and chooses UDP (TCP is specified in the contact header). The receivers are manually registered using kamctl ul add so i am not sure if this is forcing UDP or something else - I have redirected the messages to wireshark and attached an example of Kamailio adding its VIA headers but specifying UDP (taken from destination). Basically I am getting TCP to Proxy the UDP from Proxy to Dest? Thanks Andrew [image: Inline images 1]

Some Questions about Kamailio UDP Transport and Concurrency
by pengxuejin＠gangbeng.com 04 Dec '14

04 Dec '14

Dear Kamailio Developers： Hi. I have some questions about kamailio, and want to gain some suggestions from you. 1、The 4 UDP child processes are using system resources(CPU、memory), but they are using only one CPU core(I use 8 core CPU). Why? 2、The ablity of handling the Concurrency is alike, no matter how many UDP child processes I use. Why? And what's the effection of the other UDP child processes? 彭学金 186-2708-0286 技术部开发工程师武汉九午科技有限公司武汉市洪山区光谷大道国际企业中心锦丰楼A座405室 Tel:(027)87108832
