Kamailio with Dispacher
by Rodrigo Moreira 02 Sep '16

02 Sep '16

Hello, I would like to clarify a question. Can you help me? I'm deploying a solution based on Kamailio, but I need incorporate the load balancer funcionality in the environment. See the cenario: I have five VMs. PCSCF, ICSCF, SCSCF, HSS, DNS. Each VM runs the especific funcionality of the IMS. Therefore, which machines should receive the config provided by dispacher module? Is the PCSCF? Another question: The DNS server should be updated, I may do this previously? The HSS, should be updated too, I may do this previously? Do you known about approaches of the LB available? Best Regards. Thanks. -- Rodrigo M. (37) 9132-4539 (34) 9889-3069 rodrigo.moreira2007

issue with memcached module
by jay binks 02 Sep '16

02 Sep '16

if I use the memached module in kamailio to set STRING data in memcache, this is not readable from PHP. This is because kamailio uses the "val_flag" to distinguish the type of data ( int or string ). There does not appear to be a standard for how data type is indicated ( in fact the protocol doc for memcache says "<flags> is an arbitrary 16-bit unsigned integer" ) I think the memcache module really needs a way to let the user specify the value of the flag. something like a modparam to override the flag value on every set. has anyone else run in to this ? Sincerely Jay Binks

Centos, kamailio 4.4 and jansson module load issue.
by Jonathan Hunter 01 Sep '16

01 Sep '16

Hi Guys, I am running Centos 6.5 and have installed kamailio 4.4 from Git. All is running well until I try and load the jansson module. I have installed jansson-2.7 from src, but when loading the module in kamailio I get; Aug 30 20:06:24 sip1 kamailio: ERROR: <core> [sr_module.c:582]: load_module(): could not open module </usr/local/kamailio-4.4/lib64/kamailio/modules/jansson.so>: /usr/local/kamailio-4.4/lib64/kamailio/modules/jansson.so: undefined symbol: json_array_set_new Anyone else had this issue? Thanks Jon

Domain limits and domain.reload
by Bruno Emer 01 Sep '16

01 Sep '16

Hello all. I am currently working in a company that built an online platform that allows companies talk to their customer using different medias, such as video, voice and chat. To this, we are using Kamailio to provide SIP services such as WebSockets, Registrar and proxy, and ir works really well. The point is that today we are creating a new domain for each company that uses our system, and for now we have more than 3k companies using it, so my first question is: is there a limit about how many domains we can create in a Kamailio environment? I tried to find this on the documentation but I haven't found anything. Second: every time that we create a new domain, we perform a domain.reload using the XMLRPC module. We are just using the python script to do this, but sometimes it is returning the error: Fault 400: 'Reload of domain tables failed' and we don't know why. The strange thing is that if we access the server and execute a 'kamctl domain reload' just after the error, everything works fine. The problem appears to be in the RPC module. So the question is: does someone knows what can be the cause of this problem? Thanks. *Bruno Emer* Mobile: +55 11 96540-0044 email: brunoemer(a)gmail.com <https://www.facebook.com/bruno.emer.5> <https://www.linkedin.com/profile/view?id=86461237&trk=spm_pic> <https://twitter.com/brunoemer_> <https://www.flickr.com/photos/122070309@N03/> <http://google.com/+BrunoEmer> <http://instagram.com/brunoemer_>

Kamailio Errors that I see in the system logs

Htable keys and key::size inconsistencies
by Fabian Borot 01 Sep '16

01 Sep '16

Hi, I am using htable module with version 4.4 storing multiple values in the same key (I set the key_type = 1 for each entry, array key). I have found an issue with the htable module. Some keys show up when using: "./kamcmd htable.get my_table key[0]" but when asking for the "key::size" I says that the key does not exist. Also some entries have the "key::size" entry but the actual "key[0]" for example is reported as non existent: See these 2 examples: Ex:1 "key[0]" is shown but "key::size" is not: [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 8[0] { item: { name: 8[0] value: 555|5875|1.1.1.1|5060|0|4|1|1|Broadvox2010IN flags: 2 expire: NEVER } } [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 8::size error: 500 - Key name doesn't exist in htable. Ex2: "key::size" is shown but "key[0]" is not: [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 9[0] error: 500 - Key name doesn't exist in htable. [root@ar-mia-proxy-01 sbin]# ./kamcmd htable.get htable_lcrgwA 9::size { item: { name: 9::size value: 6 flags: 0 expire: NEVER } } Also, for this case "9::size", supposedly there are 6 entries and in reality there are only 4 in the tables where I am loading them from For the case "8::size" that returns 2 the count it is right , the prob is that I can not get the "8[0]" and "8[1]" keys Any ideas are very appreciated, thank you

kamailio outgoing gateway
by Andrzej Kaczmarczyk 31 Aug '16

31 Aug '16

I have common, cheap TL-WR1043ND V1 router. For private purposes I've set kamailio voip on my own server INSIDE my LAN. Is it possible to connect to that server from outside, through openWRT router? Many tries, no success - too many jumps or something similar. I guess router should be fully transparent for sip protocol. How to manage it? is it possible at all? I don't ask how to do it in details on my router/openwrt (but if someone knows, it will be nice), but - is this possible to setup at all? should I try or search for resolution, or just give up with that idea? -- Pozdrawiam Andrzej Kaczmarczyk

Looking for network version of ds_reload
by Chad McElligott 30 Aug '16

30 Aug '16

Hello all, I'm in the process of converting an on-host install of Kamailio to be run inside a docker container. A part of this Kamailio install is a small node.js application that modifies the sqlite database Kamailio uses, then runs `kamctl fifo ds_reload` to tell Kamailio to reload its knowledge from that database. I'm trying to split these two processes (the node app and the Kamailio server) into separate docker containers, in an effort to follow the one-process-per-container philosophy, but having trouble figure out exactly how I should perform the ds_reload step without access to the kamctl in the Kamailio container. The obvious direction that I'm looking is to perform some sort of network request, since I can configure the two docker containers to have network access to each other. Is there some way to perform a ds_reload over the network? Thanks for all you do. Kamailio is a great SIP server and we use it to great effect. -Chad McElligott
