"Federated" PBX solution with GUI to use with Kamailio - Suggestions needed
by George Diamantopoulos 23 Nov '17

23 Nov '17

Hello all! I'm looking at "PBX" platforms to use with kamailio as a load-balancer. This is not a strictly kamailio question, but I thought that if anyone has a suggestion to make, they would be watching this list. I'm investigating a use case with the following requirements: * Kamailio will act as a load-balancer, dispatching initial requests to PBX entities (e.g. Asterisk, Freeswitch) * PBX solution must have a single GUI interface to manage PBX functions (think FreePBX, FusionPBX etc) * Configuration via the GUI must apply to all PBX instances * Some sort of "asterisk-realtime + device state synchronization"-like setup must ensure every PBX box can service any request at any time (for failover) * Solution needn't be multi-tenant oriented, but if it is, it must work fine for single-tenant setups as well without multi-tenant capability getting in the way all the time * Feature list needn't be as full as, say, FreePBX's, but most common functionality must be available (inbound/outbound routing, trunks, queues, hunting to name a few) * Must be open source As a proprietary example, MiRTA PBX seems to check all the boxes above, apart from being open source. Now this "product" also offers high availability for databases and web apps, which is beyond the scope of this investigation. I'm only looking at a solution that provides a federated, synchronized farm of PBX instances. Any input would be greatly appreciated. Thanks! Best regards, George

Re: [SR-Users] Kamailio IMS + Asterisk PBX

My tests results : Unfortunately, no scenario was success, maybe because Asterisk does not support sh interface (Diameter) My test was for presence service and couldn’t get it done. The results of Having asterisk as an AS with kamailio IMS : with sip trunk configured towards S-cscf And whether the user is identified in Asterisk as extension user or not asterisk responded with 404 user not found.

by Atux Atux 22 Nov '17

22 Nov '17

Hi. i am new to the are of kamailio. i am looking to install in a PC running debian 9 kamailio. that is easy since all i had to do was apt-get install kamailio. I am looking on how to setup the system in a way that everyone sending a register, to be able to register no matter what user name or passwd sends. i do not want a MYSQL server on that server. Could someone give me some hints on how to configure it please? In /etc/kamailio/kamctrlc i have SIP_DOMAIN=192.168.124.5 which is my IP. Everybody from my LAN 192.168.124.0/24 network must be able to send a register with any username and any passwd and be able to register. Also from the outside world, through port forward from my router. Some hints please?

kamcmd gives segmentation fault (5.0.4)
by José Lopes 22 Nov '17

22 Nov '17

Hello, I invoke kamcmd inside Freeswitch Lua Scripts and right now i am getting segmentation fault any time. This started to happen after I upgraded kamailio from 4.4 to 5.0.4 . I tried to analyse the core dump and it give me the next information. When I execute on the console, the command works. Am I doing something wrong? There is any alternative or better way to communicate with kamailio? Thanks in advance Best regards, Jose Lopes Core was generated by `/usr/sbin/kamcmd -s udp:127.0.0.1:2050 uac.reg_refresh s:29010017'.

Kamailio IMS + Asterisk PBX
by Amar Tinawi 21 Nov '17

21 Nov '17

Dears; Good day ! is it possible to use Asterisk pbx server as an Application server for the kamailio IMS users ? as if i want to correlate an IMS user with an extension number. My though is kamailio ims will handle the registration process and authentication and Asterisk will deal with IMS users as they are PBX users to get all asterisk's benefits (call conference, monitoring, waiting, voice mail ... etc) i'm thinking to integrate Asterisk with S-cscf, and when an IMS user register to the IMS to domain, a trigger will initiate the S-cscf to send notify to asterisk . i didnt find any solution or tutorial for this procedure, and idont know if it is possible to be done. Regards Ammar

http_async_client problem with tls_ca_path
by gmele 20 Nov '17

20 Nov '17

Hello, I'm having strange behavior with the http_async_client module and https connections. Our kamailio config use REST interfaces to send push to mobile apps when calls are initiated. We also use a REST interface to register the client in our push database (and then be able to use the info to send a push). Our REST interface use TLS to cypher exchanged data between the SIP registrar and the Pusher service. We have configured the tls connection using modparam: # ------ http async client params ------- modparam("http_async_client", "workers", 16) modparam("http_async_client", "connection_timeout", 20000) # 20 seconds timeout on HTTP requests modparam("http_async_client", "hash_size", 2048) # update this value depending of the load #modparam("http_async_client", "curl_verbose", 1) # curl debug modparam("http_async_client", "tls_ca_path", "/etc/kamailio/ssl/ca") What we have noticed is when there is 1 SIP Register requests triggering and HTTPS request all works fine, but as soon as we have several HTTPS request in //, the HTTPS request fails with curl error 77: curl: (77) Problem with the SSL CA cert (path? access rights?). We tried to put the Root CA Path when building the request: $http_req(all) = $null; # reset the parameters $http_req(method) = "POST"; $http_req(hdr) = "authorization: "+$hdr(authorization); $http_req(hdr) = "Content-Type: application/json"; $http_req(suspend) = 0; # don't suspend the transaction, continue routing script's execution $http_req(body) = "{ 'pushRegistration':{'callId':'" + $ci + "', 'fromUri':'" + $fU + "@" + $fd + "', 'contactLine':'" + $ct + "'}}"; $http_req(tls_ca_path) = "/etc/kamailio/ssl/ca/"; http_async_query("https://pusher:443/rest/push/register", "HTTP_REGISTER_REPLY"); But we have exactly the same behavior. Does the http_async_client module supports muti-thread? Regards Giovanni -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

Dmq usage
by Aidar Kamalov 20 Nov '17

20 Nov '17

Hello, I want to distribute some messages-actions for redis to my kamailio servers. I use this code: For send: dmq_bcast_message("redis", "set early:$fU", "text/plain"); For recieve: request_route { xnotice("ROOT: $rm $rU [$ci]"); if(is_method("KDMQ")) { if($rU == 'redis') { route(REDIS); } else { dmq_handle_message(); } } ...... route[REDIS] { xnotice("REDIS: $rb"); redis_cmd("redis", "$rb", "r"); return; } When dmq_bcast_message starts - other node recieve 7 KDMQ sip packets. And not always it executed. Is it right way to use dmq? Dmq user locations are ok.
