Kamailio Managed Cloud
by Alex Balashov 01 Apr '19

01 Apr '19

For immediate release: ATLANTA, GA (1 April 2019)--Following its long tradition of forward-thinking innovation in open-source Real-Time Communications (RTC), the leadership of the Kamailio SIP server project (formerly known as OpenSER) has launched the Kamailio Managed Cloud (KMC). Alex Balashov of Evariste Systems and Fred Posner of The Palner Group were among several key North American stakeholders on hand to discuss it further. As Posner told us, "Kamailio Managed Cloud is a new, best-of-breed managed Kamailio hosting environment. We provide elasticity by leveraging human capital. Using our patent-pending Orchestration Turk system, our managed cloud technicians will purchase your SuperMicro bare-metal server, known as a KamBox, drive to the data centre, and rack-and-stack it on demand -- all in response to a SOAP API call! And when you want to remove your on-demand KamBox, just issue a 'delete' operation and we will decommission the hardware -- live!" "Dedicated KamBox colocation really puts the Management in Managed Cloud," emphasised Balashov. "But that doesn't mean we keep the customer out of the loop. We are using the most modern XMLHttpRequest and 'AJAX' techniques to provide a real-time dashboard with KamBox status to all users, though it will not work with Internet Explorer 6 -- we're addressing that." "Anyway, there are numerous other cloud platforms out there, many of which rely on virtualisation and automated orchestration and the like. It really takes the human touch out of the equation and gives the short shrift to quality, while also taking away jobs. And besides, how can a so-called 'virtual' machine be truly carrier-grade?" Kamailio Managed Cloud launched in two principal regions today -- US-EAST-1, located in Jacksonville, Florida, USA, and EU-CENTRAL-1, based in the booming tech hub of central Europe and birthplace of OpenSER: Berlin, Germany. Unnamed sources tell us that strategic expansion is planned for several other regions, including Flint, Michigan, USA. The mechanics of Kamailio Managed Cloud have invited questions about how other elastic cloud resources are managed, more especially elastic storage. According to KMC senior management, storage is provided via a mechanism developed by ASIPTO StorageWorks. ASIPTO chief Daniel-Constantin Mierla was on hand at the KMC launch to explain: "It's very easy. When a customer requests more space with a simple and lightweight SOAP call with just a little custom XML namespaces, then depending on the region, Fred or I receive an SMS on our smartphones from our advanced PHP backend and drive to the data centre to insert another hard drive into one of the KamBox's several drive bays. We are using the latest in advanced mobile communications, SMS, to ensure fastest response time. Of course our service level is comprehensive and includes Managed Partition Table Labelling and Managed LVM Insertion. Also there is optional Managed Filesystem Formatting for a complete portfolio of managed services. ASIPTO StorageWorks moves at the speed of global e-business. Just text us your desired filesystem layout and partitioning scheme. It is really that easy!" When asked about business focus, marketing turnaround veteran Henning Westerholt, Executive Vice President of Business Development for KMC responded: "Our target customer is a socially conscious Millennial-run corporation or start-up who see value in the unique blend of managed services and an artisanal, hand-crafted, organic approach that is compatible with social justice and takes a people-centric view." Asked to elaborate upon his vision of social justice, Westerholt added: "Virtualisation, orchestration and auto-scaling take the people out of the equation, and Kamailio is, in the end, about people, as communication in general is about people. What would it be without the people? Moreover, these mechanisms take away gainful opportunities from hard-working university graduates. Kubernetes, Docker Swarm, VMWare, and KVM contravene the social policy objective of full employment." At press time, Posner, who also heads up KMC Labs North America, was said to be lending his pioneering business vision and knack for seeing around technology trend corners to intensive work on next-generation, bleeding-edge functionality for KMC. While Posner was tight-lipped about the specifics, he did state that the 'dispatcher' module is slated to be deprecated in favour of a "human load-balancing approach to SIP requests that is both cloud-native and eco-conscious". Industry analysts agree that protocol-aware load-balancing strategies are complicated and that the application of human judgment to the problem represents a fertile field for dynamic innovation and investment. Reports from regional press confirm that KMC Labs are in the process of building a fullfilment centre for this innovative offering, said to be branded "Central Switchboard", at an undisclosed site in Bangladesh, where thousands of "Load Balance Operator" jobs have been advertised in and around the Dhaka market. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

db_redis and user
by Joan Salvatella 01 Apr '19

01 Apr '19

Hello, We are working on a project that's using two active-active Kamailio 5.2 instances that redirect traffic to several Asterisk 15.4 instances. Kamailio is acting as a registrar and should store the location information of the registered terminals. The backend database is db_redis. Phone terminals get registered and the information gets looked up from the subscriber schema in redis (That's cool) but we are having problems with the locations. This is the related code: modparam("db_redis", "keys", "location=entry:ruid&usrdom:username,domain&timer:partition,keepalive") if(ds_is_from_list("1", "2", "sip:$fd:5080")) { record_route(); route(INVITE_ASTERISK); exit; } route[INVITE_ASTERISK] { xlog("L_INFO", "[R-INVITE-RESOLVER:$ci] Entering ASTERISK INVITE resolver\n"); if (!lookup("location")) { sl_send_reply("404", "User Not Found"); return; } route(INVITE_POSTROUTE); } route[INVITE_POSTROUTE] { rtpproxy_manage(); t_on_reply("MAIN_REPLY"); if(!t_relay()) sl_reply_error(); } When looking up the location schema this errors appear: 9(39) WARNING: db_redis [redis_dbase.c:1098]: db_redis_perform_query(): performing full table scan on table 'location' while performing query 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query(): scan key 0 is 'expires' 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query(): scan key 1 is 'expires' 9(39) ERROR: <core> [db_ut.c:92]: db_str2int(): Unexpected characters: [-03-29 18:16:36] 9(39) ERROR: <core> [db_val.c:76]: db_str2val(): error while converting integer value from string 9(39) ERROR: db_redis [redis_dbase.c:1062]: db_redis_convert_row(): Failed to convert redis column 'expires' to db value 9(39) ERROR: db_redis [redis_dbase.c:1231]: db_redis_perform_query(): Failed to convert redis reply for row 9(39) ERROR: db_redis [redis_dbase.c:1243]: db_redis_perform_query(): failed to perform the query 9(39) ERROR: db_redis [redis_dbase.c:1829]: db_redis_query(): failed to do the query 9(39) ERROR: usrloc [udomain.c:981]: udomain_contact_expired_cb(): db_query failed Any hints? Thanks and regards,

Kamailio v5.2 kamctl alias add problem
by Igor Potjevlesch 01 Apr '19

01 Apr '19

Hi kamailios, I meet a problem with the " kamctl alias add" command in the 5.2 version, I saw that the module used to add an alias had changed, and now the command result with an error : [kamailio]# kamctl alias add XXXX@XXXX sip:XXXXX@XXXX { "jsonrpc": "2.0", "error": { "code": 500, "message": "Not enough parameters or wrong format" }, "id": XXXXX } I read the function who return this message " static void ul_rpc_add(rpc_t* rpc, void* ctx)" in the ul_rpc.c in the usr_loc module. I tried to pass the command with two more parameters : # kamctl alias add 0175951068(a)trunk7.bornsip.fr sip:0175951068@trunk7.bornsip.fr NULL NULL { "jsonrpc": "2.0", "result": { }, "id": 29200 } And this time it works correctly, but I saw thaht the test prameters was in the field "path" , do you know why we have to indicate a path ? Are we obliged to indicate this two more parameters ? What is the utility of this field ? Thank you in advance, Igor

recently i wrote a portion of my cfg file but i found that i based my code in other sources and results of try/tach experiments i cannot found the documents for the languaje of the core i only found the link: https://www.kamailio.org/wiki/cookbooks/devel/core but in that link there's no references about languaje per see only about how to write portions of the file and sections.. maybe i wrong or the document are wrote in different way? by example how to evaluate the output of a custom function/section?
