Call forking with delay
by Igor Potjevlesch 08 Sep '16

08 Sep '16

Hello list, I have a proxy that manage fix calls and a proxy that manage mobile calls. I want to implement call forking so when I call to a fix phone the call goes to the fix proxy and it forks to the mobile proxy who manage the call and viceversa. I want the fix to ring 2 or 3 times before the mobile. In order to do so in my fix proxy I added a diversion field with the reason "forking" and in my mobile proxy I check if the reason is "forking" to wait with the fonction "async_route" from the ASYNC module. When I call the fix I can fork to the mobile with delay without any problem because in that case my fix proxy manage one call and my mobile proxy the other one. But when I call the mobile the call doesn't even get to my fix proxy because my mobile proxy has to make the original call to wait while he is forking the fix call to my other proxy. And i think that calling the async_route fonction makes both calls to wait. My code is: Fix proxy: if($tU==123456789){ add_diversion("forking"); append_branch("sip:987654321@proxy_mobile"); } Mobile proxy: if($tU==987654321){ $var(z) = "1"; append_branch("sip:123456789@proxy_fix"); } route[INVITE]{ if($dir == "forking"){ async_route("RELAY", "7"); }else if($var(z) == "1"){ async_route("RELAY", "7"); }else{ route(RELAY); exit; } } How can I differentiate in the second scenario when I call the mobile phone to fork to the fix phone? Thank you for your help. Igor.

I know about dispatcher but it not always canbe heplfull. Sometimes i need my own logic that not implemented at the dispatcher. For checking kamailio live from asterisk im use qualfy for keepalives, if i use asterisk only as media server but it not always usefull. Sometimes scenarios need to use another logic. 2016-09-08 18:24 GMT+03:00 Yuriy Gorlichenko <ovoshlook(a)gmail.com>: > I know about dispatcher but it not always canbe heplfull.

UAC reg_contact_addr with rinstance
by DanB 08 Sep '16

08 Sep '16

Hey Guys, Have hit an issue when using uacreg. When working with Broadsoft (I know, life is not perfect), it appears that their SBC sitting in front of registration server is caching REGISTRATION requests and it will not be able to re-REGISTER in case of credential changes for example. This will break the registration process in registrar since that one flushes the registrations on password change. Their "standard" workaround it is using "rinstance" uri parameter in contact (each contact should be unique in order to be cached by their SBC). Checking it appears that I can only add rinstance statically in reg_contact_addr configuration parameter. Is there any chance to provide things like $avp or selects which I can later modify via mi maybe? Thanks in advance for any kind of tip! DanB

Query - REST API calls in async
by Agalya RAMACHANDRAN 08 Sep '16

08 Sep '16

Hi team, I am Agalya and I work for Comcast. We are trying to use kamailio as proxy server for our project. I have a query regarding the same. We are trying to use REST API calls asynchronously from the config file. I see that there is a module "http_async_client" which is used to handle REST services asynchronously. Found that libcurl is used to perform these operations. My question is: 1) How much time kamailio is taking to send the HTTP request out after TCP port is opened? Is there any time dependency we need to wait on libcurl to send HTTP request out? B'coz in opensips I see a delay time and libcurl is used in-turn. I found kamailio doing similar to opensips and hence am posting this question. 2) We can also use PUT service by using http_set_method(PUT)? Should we add code to support PUT service? Thanks in advance. Regards, Agalya

Mitigating DDOS attacks from carrier based on ani or dnis by limitating cps or blocking when detecting
by anfecora 08 Sep '16

08 Sep '16

Hi is there any way to use pike and htable to mitigate ddos or flood attack from trusted trunks. I need help to build it the same way kamailio control registrations. Case a carrier trunk star calling several users from the system to more than 50 CPS(calls per second), it will affect the system but cannot block the trunk since it is pstn traffic coming from a sip provider, therefore we need to find a way to identify this traffic based on ANI or DNIS or any other header and then blocked for a time just like pike does with registrations, then start the cycle all over. in less words make kamailio be aware of invite request rate, then verify that is from the same source means ani or dnis then tagged as bad traffic them star dropping it for a specified time, while normal traffic still flowing unaffected. any recommendations will be highly appreciated. thank you

Resume suspended invite transation after x seconds
by José Seabra 06 Sep '16

06 Sep '16

Hello, I have the following scenario: Kamailio is suspending an INVITE then generates a SUBSCRIBE msg to an external server with UAC module, and only resume the suspended INVITE when receives an NOTIFY(this NOTIFY "belongs" to the SUBSCRIBE dialog) from the external server. The issue is that sometimes kamailio doesn't receive a NOTIFY and the transaction is not resumed, any one have an idea how can i implement a solution to resume the suspended invite after x seconds without receiving NOTIFY msg? Best Regards -- José Seabra

detect failed socket
by Péter Barabás 05 Sep '16

05 Sep '16

Hello, I want to refine the instant message handling in our application. It works really fine in most cases. I use the msilo module to store offline messages if the user is not registered with sending PUSH notification. But, there is a situation when I have problems: When I send a message to a user whose phone is in airplane mode. In this case his location record exists but the communication on the socket is not possible and the client timed out the request. Is it possible to check the socket towards the receiver user at the moment when the message arrives at Kamailio? I think if I would check that if the socket is not fine, I could send the message to the msilo directly and the client would not have wait for timeout to resend. Thanks. Peter

Just dont know what i need to change. I will be very grateful if someone heps me to resolve this issue. Thanks

Kamailio - passing registration to another sip server
by Mike Patterson 05 Sep '16

05 Sep '16

I have configured Kamailio to pass a registration request to another VoIP provider. The reason I am doing this is to provide a sip port for users where the ISP is blocking SIP. I am able to pass the registrations to the VoIP provider but I'd like to have inbound calls working as well. I see the inbound invites coming into the Kamailio server but it appears that the server does not 'know' about the UA that is registered 'through' the server to the VoIP provider. Can anyone tell me how to fix this problem? Below is my config. Thank you, Mike #!KAMAILIO # # Edge proxy configuration # #!subst "/REGISTRAR_IP/xxxxxxxxxx/" #IP address of voip provider #!subst "/REGISTRAR_PORT/5060/" #!substdef "/FLOW_TIMER/20/" debug=2 log_stderror=no log_facility=LOG_LOCAL0 fork=yes children=4 alias="example.com" #mpath="/usr/lib64/kamailio/modules" mpath="/usr/lib/x86_64-linux-gnu/kamailio/modules" tcp_connection_lifetime=30 # FLOW_TIMER + 10 auto_aliases=no mhomed=0 listen=udp:X.X.X.X:531 advertise X.X.X.X:531 alias="X.X.X.X:531" alias=X.X.X.X:531 alias="X.X.X.X:531" alias=X.X.X.X:531 port=531 ####### Modules Section ######## loadmodule "tm.so" loadmodule "sl.so" #loadmodule "outbound.so" loadmodule "rr.so" loadmodule "path.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "mi_rpc.so" loadmodule "mi_fifo.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "rtimer.so" loadmodule "sqlops.so" # ----------------- setting module-specific parameters --------------- # ----- mi_fifo params ----- modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") # ----- tm params ----- modparam("tm", "failure_reply_mode", 3) # ----- rr params ----- modparam("rr", "append_fromtag", 0) ####### Routing Logic ######## request_route { route(REQINIT); if (is_method("CANCEL")) { if (t_check_trans()) { route(RELAY); } exit; } route(WITHINDLG); t_check_trans(); if (is_method("REGISTER")) { remove_hf("Route"); add_path(); $du = "sip:REGISTRAR_IP:REGISTRAR_PORT"; } else { if (is_method("INVITE|SUBSCRIBE")) record_route(); if ($si == "REGISTRAR_IP" && $sp == "REGISTRAR_PORT") { if (!loose_route()) { switch($rc) { case -2: sl_send_reply("403", "Forbidden"); exit; default: sl_reply_error(); exit; } } t_on_failure("FAIL_OUTBOUND"); } else { if ($rU == $null) { sl_send_reply("484", "Address Incomplete"); exit; } remove_hf("Route"); $du = "sip:REGISTRAR_IP:REGISTRAR_PORT"; } } route(RELAY); } route[RELAY] { if (!t_relay()) { sl_reply_error(); } exit; } route[REQINIT] { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(!sanity_check("1511", "7")) { xlog("Malformed SIP message from $si:$sp\n"); exit; } } route[WITHINDLG] { if (has_totag()) { if (!loose_route()) { switch($rc) { case -2: sl_send_reply("403", "Forbidden"); exit; default: if (is_method("ACK")) { if ( t_check_trans() ) { route(RELAY); exit; } else { exit; } } sl_send_reply("404","Not Found"); } } else { if (is_method("NOTIFY")) { record_route(); } route(RELAY); } exit; } } onreply_route { if (!t_check_trans()) { drop; } if ($rm == "REGISTER" && $rs >= 200 && $rs <= 299) { remove_hf("Flow-Timer"); if ($(hdr(Require)[*])=~"outbound") insert_hf("Flow-Timer: FLOW_TIMER\r\n", "Call-ID"); } } failure_route[FAIL_OUTBOUND]{ if (t_branch_timeout() || !t_branch_replied()) { send_reply("430", "Flow Failed"); } }

VUC - SER-Kamailio At 15 Years - On Friday, Sep 2, 2016
by Daniel-Constantin Mierla 02 Sep '16

02 Sep '16

Hello, on September 3, 2001, the first line of code was committed to SIP Express Router (SER) project, since 2008 turning into Kamailio project. >From pioneering large scale deployments of using SIP for Voice over IP in early 2000s, the project impacted the evolution of real time communications, disrupted the telecom vendors with its open source model and enabled many businesses to grow and innovate. Let's get together to a VUC session later this week, on Friday, Sep2, 2016, to share the good or bad stories while using SER or Kamailio during the past 15 years. If it made your life easy or a nightmare, it's time to tell it. If you have a funny photo or video, no matter is old or recent, join us and show it. More details about VUC and how one can join or watch the session are available at: - https://vuc.me If you want to actively participate during the session, email me shortly to coordinate a bit. If you cannot participate but you have something interesting to share (story, media files, etc...) email me as well and I will present it.

Kamailio with Dispacher

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

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_>

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

uac_auth and (serial) forking
by Daniel Tryba 30 Aug '16

30 Aug '16

Trying to implement a way to authenticate outgoing INVITEs to endpoints that need/want to. uac_auth in the initial failure route works fine when there is only 1 registered user to send the INVITE to. But with at least 2 locations are available and 1 accepts the INVITE without authentication, the 401 of the location that wants authentication isn't processed in the failure route until a timeout is triggered (t_set_fr). At that point the 401 is processed and a response generated with Authentication header. But since t_set_fr invite timeout was exceeded it is immediatly destroyed due to a CANCEL having been generated to the location(s). t=0: t_set_fr(10000); INVITE to A anb B A responds 100 Trying,180 Ringing B responds 401 Unauthorized t=10s: T_code=180, new_code=408 failure route status: 401 uac_auth() INVITE with Authorization is build to B CANCEL to A INVITE to B is never send Is this expected behaviour? Obviously I didn't expect this.

Configuration Issue on Kamailio.
by Laura 30 Aug '16

30 Aug '16

Dear list, i'm asking here a question about Kamailio config. We are testing a wide area configuration of Kamailio over separates countries and we are still facing with an issue. We configured Kamailio 4.3.5 with dialog support over the TM modules and we use LCR module for menage ours LCRs rule set profiles. For some technicals reasons we use tech prefix for our customer so for exaples customer1 send traffic to us with 1111 prefix, customer2 send traffic to us with 2222 and something similar.. Our supplier, of course, are using tech prefix too so for examples if i want to send the call to supplier1 i need to use tech prefix 1789 or something similar.. The point is.. When customer1 is sending an invite to us.. it send us something like (Bangladesh mobile 8801xxx) INVITE sip:11118801xxxxxxx@aaa.bbb.ccc.ddd Our Kamailio will reply with the Trying and then it goes to LCR module and match our supplier1 so it make a new invite like this INVITE sip:17898801xxxxxx@supplier.ip The problem come when supplier1 reply to us and we replies back to customer1.. Customer1 view the From: field with the 17898801xxxxxx numbers.. and some of our customers don't like it. We don't use anymore the topoh module becuase we found some troubles using it.. so.. Is there a way that we can use for fix this situation ? Best regards.

Kamailio and user registration and a question on STUN servers
by Kevin Greene 29 Aug '16

29 Aug '16

Hello Group: I am looking for a way to allow any SIP client to register to my (development) network without having to be already registered in the database. Is there a way for the user client to register and create a valid user subscription in the database? The SIP clients I am using have hard coded passwords and I can not change them. I think once loaded into the database, I can delete the ones I do not want later after I close automatic registration feature... The second question is on STUN servers. Is there a good way to test to see if one is working from outside your network? I was looking for some sort of web based tool I could access to see if my public STUN server is really working. I am using the "reTurnServer" software on Linux. I am only allowing TCP based STUN requests. Thank you. Sample log entry for a external user trying to access the development network. I would like to give this person access to place calls on the system. 199.58.xxx.xxx.nebraskalink.com - - [25/Aug/2016:18:02:49 +0000] "GET /download/?ojo-mac=00:02:54:00:a5:eb&ojo-id=2000-0005-2F52&ojo-rev=rev02.01.15&ojo-config-id=e712e6cb088ab9b4ef246488b979cbf6&ojo-stun-type=Blocked&ojo-sn=15190252560146703100&ojo-key-id=e0142f126a5197845a24f33deedc358645e67e5f HTTP/1.0" 200 1812 "-" "Wget/1.9.1"

Monitor diameter state and number of current calls

23 Aug '16

Hi, We would like to know if there is some way to check the state of a diameter connection (to see is it's in state 6: connected), inside the kamailio configuration script. Also we would like to know if there is a way to see the number of current calls in a kamailio through kamcmd, kamctl or something like that. We have searched for a solution but we don't find anything. Many thanks.

Howto timeout INVITEs over TCP to something < 30s?
by Daniel Tryba 22 Aug '16

22 Aug '16

If an enduser INVITEted over TCP t_set_fr(t) with t < 30s have no effect, the INVITE will always timeout after 30s. What is controlling this 30s? The only default at 30s is the fr_timer, which should have no part in the timeout between an 1xx and a final answer for an INVITE.

Evapi module is not broadcasting any data

Hi folks, I came into a problem with evapi module, while I was trying to make the CGRateS tutorial work. It does not send any messages at all. Taken steps: I start kamailio with debug=3. I start: CGRates (on the kamailio machine) telnet 192.168.30.29 8448 (from my PC) tcpdump port 8448 -A -s0 -i any (on the kamailio machine) Telnet command successfully connects to kamailio.

Running both 4.3 and 4.4 with the same database with permission module
by Daniel Tryba 19 Aug '16

19 Aug '16

I want to upgrade my cluster from 4.3 to 4.4, beginning with the spare for live testing. But since there is a change to the trusted table (which we don't use, only address) this isn't possible without some tricks. There is no override for skipping the version check on any permissions table. I need to share the subscriber/location/address/usr_preferences and db_aliases tables between the 4.3 and 4.4 machines. The only thing I can think of is: -patch the permissions module to accept the old version of trusted -create a 4.4 database and use federated tables to access the 4.3 data Not hard to implement any of these 2, but some other modules have the option to skip these checks, eg: http://www.kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.p.v… Is there a reason not all modules have this flag (which you could use at your own risk)? Or am I missing something here?

Trouble with nat_uac_test()
by Noah Mehl 18 Aug '16

18 Aug '16

Hey all, I have a Kamailio implementation (version: kamailio 4.4.1 (x86_64/solaris) 12b048) as part of the Kazoo platform. I’m having an odd problem with an e2e ACK (after a 200OK after a T38 re-invite), which I’m pretty sure has to do with a Contact header rewrite due to the following (can review attached PCAP for specifics): if (nat_uac_test("3")) { force_rport(); fix_nated_contact(); } I have a couple of questions about this: A flag of 3, I don’t understand. I read the documentation <http://kamailio.org/docs/modules/4.4.x/modules/nathelper.html#nathelper.f.n…>, and there is a 1,2,4,8,etc… So, I’m guessing that a flag of 3, means 1+2? If #1 is true, then "the "received" test is used: address in the “Via” header is compared against source IP address of signaling” I don’t understand this test, as I’m pretty sure that the 200OK that’s getting re-written is properly constructed. I guess I’m trying to understand when one would want to use this test? Thanks! ~Noah

I copied the provided route statement , and edited it so will be similar to route functions that are already there. that was the outcome: # Routing to MSILO route[MSILO] { #!ifdef WITH_MSILO if ( !mf_process_maxfwd_header("10") ) { sl_send_reply("483","To Many Hops"); exit; }; if (uri==myself) { { # for testing purposes, simply okay all REGISTERs if (method=="REGISTER") { save("location"); log("REGISTER received -> dumping messages with MSILO\n"); # MSILO - dumping user's offline messages if (m_dump()) { log("MSILO: offline messages dumped - if they were\n"); }else{ log("MSILO: no offline messages dumped\n"); }; exit; }; # domestic SIP destinations are handled using our USRLOC DB if(!lookup("location")) { if (! t_newtran()) { sl_reply_error(); exit; }; # we do not care about anything else but MESSAGEs if (!method=="MESSAGE") { if (!t_reply("404", "Not found")) { sl_reply_error(); }; exit; }; log("MESSAGE received -> storing using MSILO\n"); # MSILO - storing as offline message if (m_store("$ru")) { log("MSILO: offline message stored\n"); if (!t_reply("202", "Accepted")) { sl_reply_error(); }; }else{ log("MSILO: offline message NOT stored\n"); if (!t_reply("503", "Service Unavailable")) { sl_reply_error(); }; }; exit; }; # if the downstream UA does not support MESSAGE requests # go to failure_route[1] t_on_failure("1"); t_relay(); exit; }; # forward anything else t_relay(); } failure_route[1] { # forwarding failed -- check if the request was a MESSAGE if (!method=="MESSAGE") { exit; }; log(1,"MSILO:the downstream UA doesn't support MESSAGEs\n"); # we have changed the R-URI with the contact address, ignore it now if (m_store("$ou")) { log("MSILO: offline message stored\n"); t_reply("202", "Accepted"); }else{ log("MSILO: offline message NOT stored\n"); t_reply("503", "Service Unavailable"); }; } #!endif return; } but after that I restarted kamailio service and got the following errors: root@debian:~# service kamailio restart Job for kamailio.service failed.

t_set_fr() different behavior whether transport is udp or tcp
by Daniel Tryba 16 Aug '16

16 Aug '16

I'm seeing a different behavior of t_set_fr depending on transports. Scenario is that a endpoint has a failover defined in the registrat after 10s (t_set_fr(10000) and handling the locally generated 408 to the failover destination). This works fine when the request and response where delivered over UDP. When the Path is TCP the failover happends after 30s (even when using a different time t_set_fr(20000) so it is not a factor 3 or something like that). Setup: OK, 10s: Orig->UDP->loadbalancer->UDP->registrar->UDP->loadbalancer->TCP->Term Fail, 30s: Orig->UDP->loadbalancer->TCP->registrar->TCP->loadbalancer->TCP->Term Loadbalancer and registrar are kamailio machines (4.3.6). Communication between lb and registrar is based on dispatcher and path modules. 1 sip:registrar:5060;transport=udp 8 0 or via tcp: 1 sip:registrar:5060;transport=tcp 8 0 In the location database of the registrar the difference between the cases is: socket: udp:registrar:5060 or via tcp tcp:registrar:5060 path: <sip:lb@loadbalancer;lr;received=sip:1.2.3.4:5067%3Btransport%3Dtcp> or via tcp <sip:lb@loadbalancer;transport=tcp;lr;received=sip:1.2.3.4:5067%3Btransport%3Dtcp> Looking at debug(=3) nothing happens between the initial INVITE and the local 408 as far as I can see.

302 - stop sending once ACKed
by jaflong jaflong 16 Aug '16

Is ACK required in a re-invite?
by Jay Li 15 Aug '16

15 Aug '16

Dear All, I just have a basic SIP question on re-invite. I wonder if "ACK" is required in a re-invite scenario, like re-invite -> 200 OK -> ACK. What I've seen is for some reason, my PSTN doesn't send a "ACK" back to me after my 200 OK response to their re-invite. I don't know if not sending an ACK in a re-invite is an allowed behavior. Thanks. Regards,Jay

Via in locally generated PUBLISH (using different presence server address)
by Asgaroth 15 Aug '16

15 Aug '16

Hi All, I have a configuration where we run a multi-homed proxy/loadbalancer and a seperate internal presence server. We then use pua/pua-dialoginfo on the proxies to publish dialog state to the internal presence server. The proxies listen on udp:external_ip:5062 and udp:internal_ip1:5060. The presence server listens on udp:internal_ip2:5060 on a seperate server. The problem I am coming accross is that when kamailio generates a PUBLISH message for some dialogs it creates the via header with address external:ip:5062, however the pua module is configured to send to the presence server address on internal_ip2:5060. I have a route which forces the sending socket ($fs) to be udp:internal_ip1:5060. What happens then is that the presence server tries to send the 200 reply to the PUBLISH message back to internal_ip1:5062 (when it should be internal_ip1:5060), I'm thinking this is because the Via header has host as external_ip:5062. Is it possible, from event-route[tm:local-request] to rewrite the via header so that it reflects internal_ip1:5060 instead of external_ip:5062? I did try the following snippet from event-route[tm:local-request], but I got module parse errors on the Via header: if (is_method("PUBLISH")) { subst_hf("Via", "/ 1\.2\.3\.[0-9]+:5062;/ $sel(cfg_get.socket.internal_ip);/", "f"); } [7370]: ERROR: <core> [parser/parse_via.c:2607]: parse_via(): ERROR:parse_via on <1> state 5 (default) [7370]: ERROR: <core> [parser/parse_via.c:2708]: parse_via(): ERROR: parse_via on: <SIP/2.0/UDP external_ip:5062;branch=z9hG4bK96eb.0f014ae4000000000000000000000000.0#015#012 internal_ip1; [7370]: ERROR: <core> [parser/parse_via.c:2712]: parse_via(): ERROR: parse_via parse error, parsed so far:<SIP/2.0/UDP external_ip:5062;branch=z9hG4bK96eb.0f014ae4000000000000000000000000.0#015#012 > [7370]: ERROR: <core> [parser/msg_parser.c:125]: get_hdr_field(): ERROR: get_hdr_field: bad via [7370]: INFO: <core> [parser/msg_parser.c:338]: parse_headers(): ERROR: bad header field [Via: SIP/2.0/UDP 1] [7370]: ERROR: <core> [parser/msg_parser.c:690]: parse_msg(): ERROR: parse_msg: message=<PUBLISH sip:user@domain;transport=UDP SIP/2.0#015#012Via: SIP/2.0/UDP external_ip:5062;branch=z9hG4bK96eb.0f014ae4000000000000000000000000.0#015#012 internal_ip1;To: <sip:user@domain;transport=UDP>#015#012From: <sip:user@domain;transport=UDP>;tag=3e8fdaca277026bf3e6d75c5e5313096-f162#015#012CSeq: 10 PUBLISH#015#012Call-ID: 5634294b786134b3-7370@external_ip#015#012Content-Length: 692#015#012User-Agent: kamailio (bfievklb04)#015#012Max-Forwards: 70#015#012Event: dialog#015#012Expires: 10901#015#012Content-Type: application/dialog-info+xml#015#012#015#012<?xml version="1.0"?>#012<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:user@domain;transport=UDP">#012 <dialog id="mvqXXaAr24DHdfsffYKZeA.." call-id="mvqXXaAr24DHdfsffYKZeA.." direction="initiator">#012 <state>Trying</state>#012 <remote>#012 <identity>sip:1234567@domain;transport=UDP</identity>#012 <target uri="sip:1234567@domain;transport=UDP"/>#012 </remote>#012 <local>#012 <identity>sip:user@domain;transport=UDP</identity>#012 <target uri="sip:user@domain;transport=UDP"/>#012 </local>#012 </dialog>#012</dialog-info>#012> [7370]: ERROR: <core> [msg_translator.c:3057]: build_sip_msg_from_buf(): parsing failed [7370]: ERROR: tm [uac.c:163]: uac_refresh_hdr_shortcuts(): failed to parse msg buffer [7370]: ERROR: tm [uac.c:487]: t_uac_prepare(): failed to refresh header shortcuts [7370]: ERROR: pua [send_publish.c:700]: send_publish(): in t_request tm module function [7370]: ERROR: pua_dialoginfo [dialog_publish.c:358]: dialog_publish(): while sending publish To me, it looks like the replace section of the subst_hf sub expression is being appended to the end of the via header instead of replacing the address section found.

Re: [SR-Users] kamailio starts looping invites(some) back to itself.
by SamyGo 10 Aug '16

Hi Aqs, How about putting a loop protection of some sort additionally like $si != myself. Is there any chance the API http call is getting skipped to relay w/o getting any reply back and hence looping back to itself ? Regards, Sammy On Jul 22, 2016 14:17, "Aqs Younas" <aqsyounas(a)gmail.com> wrote: Hi, I am using http_async_client and dispatcher modules of Kamailio. Here is scenario! http_async_client makes calls to an API to get groupid upon which dispatcher sends calls. I am using SIPp to generate calls with 100 cps. I see some calls being failed with an error cause, 483 Too Many Hops. Taking the trace shows Kamailio routing some calls to itself. I think this is not a configuration issue since all calls are same(follow same logic) and some calls get failed. Any pointer is much appreciated.

Duplicate ACC records in db when using db_cluster
by Jan Hazenberg 09 Aug '16

09 Aug '16

Hi, I have a issue with the db_cluster module. All works fine but when i enable ACC records to the database i get duplicate entry's in the acc table. I have 2 nodes enabled: # ----- db_cluster params ----- modparam("db_cluster", "connection", "con1=>mysql://kamailio:password@10.1.1.1/kamailio") modparam("db_cluster", "connection", "con2=>mysql://kamailio:password@10.1.1.2/kamailio") modparam("db_cluster", "cluster", "cls1=>con1=9s8p;con2=9s8p") When i remove one node from the pool the acc records look fine. Could this be a bug? Or should i bypass the db_cluster for accounting? I'm running kamailio 4.4.2. Thanks, Jan Hazenberg

TCP message parsing & connection close issue
by Alex Balashov 08 Aug '16

08 Aug '16

Hello, I've got an odd issue where: 1. TCP client makes call out through Kamailio. 2. Call is answered, TCP client sends e2e ACK. 3. Parser chokes on ACK, closes TCP connection (SYN+FIN). 4. Subsequent messages from the client, immediately following the ACK (about 240 ms later), come through because the client is halfway around the world - about 250 ms away - and is not yet aware the connection has been closed. Otherwise, it would presumably try to re-establish the connection before sending anything. Anyway, messages from the parser concerning the ACK are: --- Aug 4 21:55:57 sip-proxy /usr/local/kamailio/sbin/kamailio[14680]: INFO: <core> [parser/parse_fline.c:144]: parse_first_line(): ERROR:parse_first_line: method not followed by SP Aug 4 21:55:57 sip-proxy /usr/local/kamailio/sbin/kamailio[14680]: ERROR: <core> [parser/parse_fline.c:257]: parse_first_line(): parse_first_line: bad message (offset: 0) Aug 4 21:55:57 sip-proxy /usr/local/kamailio/sbin/kamailio[14680]: ERROR: <core> [parser/msg_parser.c:690]: parse_msg(): ERROR: parse_msg: message=<0#015#012a=rtcp:4007 IN IP4 1.1.1.1:1071#015#012a=sendrecv#015#012a=rtpmap:0 PCMU/8000#015#012a=rtpmap:8 PCMA/8000#015#012a=rtpmap:96 telephone-event/8000#015#012a=fmtp:96 0-16#015#012ACK sip:*98*0b3ff883-a89d-4317-b758-8979682f5357@10.0.2.53:5060;transport=udp SIP/2.0#015#012Via: SIP/2.0/TCP 1.1.1.1:61979;branch=z9hG4bKPjc15bf9fdded940cab7f859634b9f036e;alias#015#012Max-Forwards: 70#015#012From: sip:4b57be8d-267d-48c4-aa82-0f3a269d74cb@sip.evaristesys.com;tag=dd1d7fd0344d47b7b22c4017091df17a#015#012To: sip:*98*0b3ff883-a89d-4317-b758-8979682f5357@sip.evaristesys.com;tag=2rZDKcBFmU65S#015#012Call-ID: 5ba5a84451074159aaaa931eb1f98fe5#015#012CSeq: 3071 ACK#015#012Route: <sip:2.2.2.2;transport=tcp;lr;r2=on;ftag=dd1d7fd0344d47b7b22c4017091df17a;rtp_set_id=1>#015#012Route: <sip:10.0.2.119;lr;r2=on;ftag=dd1d7fd0344d47b7b22c4017091df17a;rtp_set_id=1>#015#012Content-Length: 0#015#012#015#012> Aug 4 21:55:57 sip-proxy /usr/local/kamailio/sbin/kamailio[14680]: ERROR: <core> [receive.c:173]: receive_msg(): core parsing of SIP message failed (1.1.1.1:61979/2) --- That doesn't look like a clean message buffer to me.

Prepaid system using dialog and sqlops
by Infinicalls Infinicalls 06 Aug '16

06 Aug '16

Hi, I am still struggling to get a prepaid system for my service. After installing SIREMIS, I am able to get the CDRs updated. But even after adding the cron settings, the call duration doesn't get updated. And also in http://lists.sip-router.org/pipermail/sr-users/2012-January/071517.html it has been mentioned that "If it is the case of 1 call per user at a time, then practically can be done from kamailio config only. When call starts, compute the max duration for that call based on caller/destination (e.g., call a stored procedure via sqlops) and set the dialog timeout to that duration. When call ends (BYE in main route or timeout route) update the credit accordingly." Can somebody let me know if my understanding is correct. 1) Add a field called "credits" in the database. And topup that field. 2) First compute max permitted duration for that user by multiplying the cost for number prefix (say +91) and pulse. 3) And finally add this value to timeout of dialog. modparam("dialog", "default_timeout", 100000) $dlg_ctx(timeout_bye) = 1; Will this work? Any help would be appreciated. regards Ganesh Kumar

e2e ACK. Kamailio. Cantact. Route.
by pavel＠eremina.net 05 Aug '16

Hello, I have this scheme: SIP Carrier (external IP 22.203) < > (local ip 1.21) mikrotik < > (local ip 1.21) Kamailio - (local ip 1.15) Asterisk. Carrier does not know what is Route header. that is why Carrier send ACK directly to 1.15 and fail. I change Contact at Kamailio to 1.21 then ACK is coming to Kamailio. But i think it's wrong way... How can i get ACK from CArrier to Kamalio and route it in right way? Thanks

Hello, if you know the ip address associated with the network interfaces, you can use keyword dst_ip to check which of the ip addresses was used to receive the packet (or use $Ri instead of dst_ip).

Kamailio on multiple interface

Hi guys, I've my Kamailio box that works great J Now I would like to enable wifi on the board (in AP mode) in order to allow mobile devices to connect and receive and place calls. Is it possible? Is it possible to configure Kama like a "gateway" between two network cards? I've find a guide regarding gateway between IPv4 and IPV6 but i can't use "af" to discriminate message between eth0 or wlan0. Is there a command to detect if a message is received from a specific interface card? Any help or any cfg example is very appreciate J Marino Maria Mileti <mailto:marino.mileti@alice.it> marino.mileti(a)alice.it cid:006a01cb6b0e$67eecdae$_CDOSYS2.0Reduce your energy consumption and keep polar bears on ice! --- Questa e-mail è stata controllata per individuare virus con Avast antivirus. https://www.avast.com/antivirus

CDP -Could not open module error

01 Aug '16

Hi All, I have just installed KamailioIMS 4.4.2 on a Ubuntu 16.04 vm and configured it according to the kamailio tutorial. When l attempt to start the icscf or scscf kamailio, it fails to start due to its inability to open the CDP module referring to the log_db_config function in particular.I have looked at the archive to see if anyone else have encountered this problem, but could not find anything. The log_db_config function takes a config object as a parameter, hence l have inspected the CDiameterPeer config file carefully and it seems both xml and diameter compliant. I am at loss where else to look. Please would anyone be kind enough to assist with getting a scscf and icscf started please. Regards Andrew

Kamailio LB: how to get Asterisk to do the RTP
by Tickling Contest 28 Jul '16

28 Jul '16

With the help of members from this mailing list (many thanks!), I finally got Asterisk fronted by Kamailio for LB and REGISTERs and I am able to make a call using the setup that looks like this: [Kamailio 4.4.2]<->[Asterisk 13.7.2] Kamailio manages REGISTERs, but also forwarding them to Asterisk. I am able to make a call, but I get only one way audio or no audio depending on which client made the call (SipDroid->Zoiper I hear one way audio on Zoiper, but no audio if the call is made the other way). I noticed that Kamailio forced direct media between the endpoints in this situation, but my application really needs Asterisk to handle it. How do I do this? Should I start by forwarding INVITEs to Asterisk? How do I do that? Any help is appreciated. Thanks!

undefined symbol: EVP_sha1 when using outbound module
by Francisco Burgos 28 Jul '16

28 Jul '16

Hi, I am trying to use kamailio as an edge proxy to forward requests and media to an sbc. when compiling the cfg file included on the examples. i get: undefined symbol: EVP_sha1 I believe this problem is being caused by the outbound module and after some research i managed to read that it is caused by the linking between the gcc libcrypto. I would like some help since this project requires urgency. Thanks in advance.

TM: t_relay([host, port]) DNS Queries
by Louis-Olivier Roof 27 Jul '16

27 Jul '16

Dear Kamailio users, Ref: http://kamailio.org/docs/modules/4.2.x/modules/tm.html#tm.f.t_relay Using t_relay([host, port]) to relay messages to a specific host does not seem to generate DNS queries to the said host after Kamailio has initially processed the configuration file. It resolves the host once at startup then continues using the same IP after. Is that expected behavior? Anyone has had this issue before and found a way to work around it? Note that for this specific application, messages need to be relayed to a specified host (different from current R-URI) and this host needs to be resolved by DNS during normal operation, not only at startup. Thanks! Louis-Olivier

Checking for 200ok Response to a REGISTER request kamailio-Asterisk
by Jonathan Hunter 27 Jul '16

27 Jul '16

Hi Guys, So currently on our network we have a kamailio server which users register against, we then replicate the register messages to 2 Asterisk boxes sat behind it so that all entities are aware of the registration state of the users. REGISTER--->KAMAILIO---->ASTERISK A ---->ASTERISK B With a REGISTER---200OK exchange between Kamailio and Asterisk. We have an issue where at some points the Asterisk servers when under load dont respond with a 200 ok(something being investigated) to the register messages sent to kamailio, so I am just working on some logic for the register message to be resent using the t_replicate and t_set_fr functions. This works well should both Asterisk servers not respond, however, as I am using replicate and it is parallel forking, if say Asterisk A answers first and is available with a 200ok then that in turn cancels the register message branch being sent to Asterisk B(which I know is fine), however there could be a scenario where Asterisk B doesnt respond, and we wont know about it to try and resend the Register message, as the branch is cancelled. Hope that makes sense? I am looking at checking that both the Asterisk servers have responded and sent a 200ok, which I can grab in an onreply route but Im just wondering if someone has done something similar or has any suggestions as it is tricky to achieve currently. I have also thought about stateless working but I really need kamailio to keep retransmitting the register until it gets a response. Many thanks Jon
