Kamailio - Sip_capture Module
by Ali Taher 05 May '16

05 May '16

Hello, We are currently using kamailio sip_capture module, and then we need to create a Wireshark file (pcap format)from fields in the database. As we noticed in sip_capture table there is msg fields that contains only the sip content. And in order to create our file we need to have the entire packet and not part of it. We are hopefully asking if you can give us a hand with that , beside the Homer project, what we actually wanted is to know if there is another module in kamailio that store the entire packet captured and not only the part of it. Regards, Ali Taher

Hello all, is there anyway to pause a transaction for a short while (1 second) ? I have implemented the push notification, when the callee get register I need a short time to be sure that the app is completely start and can do its duty. otherwise it missed the call. so I want to pause the transaction. I have tested async_sleep("1"); it worked. is there any better solution ? $var(hjoin) = 0; lock("$tU"); async_sleep("1");

ACK not forwarded by Proxy when LOCATION lookup
by Al S 05 May '16

05 May '16

Hi, I am trying to simulate Inbound calls from UAC to Kamailio to UAS. Kamailio performs location lookup within route[LOCATION] and updates URI with the address of UAS. However, it does not add a new Record-Route. Therefore, ACK message sent by UAC is not routed by the proxy: UAC ---> (send INVITE) ---> Kamailio ---> (send INVITE) ---> UASUAS ---> (send 180) ---> Kamailio ---> (send 180) ---> UACUAS ---> (send 200) ---> Kamailio ---> (send 200) ---> UAC UAC ---> (send ACK) ---> Kamailio ???? ACK message has "Route" header with the address of Proxy. Thanks,AI S

You must register first with a S-CSCF/Server error on LIR select next S-CSCF
by 王欣鑫 05 May '16

05 May '16

Hello, I'm using kamailio and OpenImsCore HSS module to set up an IMS enviroment(P/I/S-CSCF and HSS). All these four modules are set up in one cloud server in public network with different ports(4060/4061 5060 6060 3869 3870) to commonicate with each other. Now I have two users Alice and Bob, they are in private network. I can register Alice and Bob with ImsDroid on this IMS, however when I use Alice to call Bob, I can see "You must register first with a S-CSCF" error. As I found this was caused by kamailio.cfg in pcscf module, I comment out these lines below. Then I got another error "Server error on LIR select next S-CSCF". And I captured packets on port 5060, I can see several "Request-Line: OPTIONS sip:sbc-2.ng-voice.com SIP/2.0" and "Request-Line: OPTIONS sip:sbc-1.ng-voice.com SIP/2.0". #if (!pcscf_is_registered("location")) { # send_reply("403","Forbidden - You must register first with a S-CSCF"); # break; #} What's wrong with my IMS? Could any body give me some help? Thank you! Here are my IMS configure files. kamailio.zip <http://sip-router.1086192.n5.nabble.com/file/n148131/kamailio.zip> Here are my hss configure files. hss_config.zip <http://sip-router.1086192.n5.nabble.com/file/n148131/hss_config.zip> -- View this message in context: http://sip-router.1086192.n5.nabble.com/You-must-register-first-with-a-S-CS… Sent from the Users mailing list archive at Nabble.com.

Using Kamailio as UAC on any PBX
by Jöran Vinzens 04 May '16

04 May '16

Hi All, we are trying to use the Kamailio as an UAC on a PBX. It should behave just like a normal SIP UAC (e.g. an SNOM phone). The reason why we want that, is connecting a service to any other PBX with Client features and security (DA). Our setup looks like: Kamailio UAC w/ register <-> Kamailio OBP/SBC <-> PBX The register is working fine. We insert the credentials into DB and trigger kamailio to reload the config (kamctl uac.reload). Then the register is sent out including the unauth (401) handling. After than we are registered on the PBX. The Register is sent though the OBP as configured in DB. We are trying to make calls: Calls from PBX to Kamailio are working fine but we struggle with calls from kamailio torwards PBX. We have the l_uuid in a variable and we try to get the PV ready for the invite. First we need to do is rewrite the "from" URI. We thought we can get a proper FROM URI with the uuid we have. But the uac_replace_from just sets the $fu as given and does not make any logic with UAC credentials. To handle the RURI, we trigger uac_reg_lookup with the uuid and it replaces the $ru with user-name and domain from the data stored in DB. In this case that makes no sense. The $rU should be what the user had dialed, the $rd should be the server given in uacreg DB table. The OBP given in DB is ignored completely. After we managed to rewrite everything in SIP as needed we try to catch the 407 as it's shown in the module documentation with failure route. Here we have not found any way to get the credentials for the uuid. Now we wonder if we have missed any global setting which sets everything right. If anybody has a similar setup and a working config, we appreciate any help we can get. our config looks like: ... loadmodule "uac.so" .... modparam("uac","auth_realm_avp","$avp(arealm)") modparam("uac","auth_username_avp","$avp(auser)") modparam("uac","auth_password_avp","$avp(apass)") modparam("uac","restore_from_avp","$avp(original_uri_from)") modparam("uac","restore_to_avp","$avp(original_uri_to)") modparam("uac","credential","username:domain:password") modparam("uac", "reg_db_url","DBURI") modparam("uac", "reg_timer_interval", 60) modparam("uac", "reg_retry_interval", 300) modparam("uac", "reg_contact_addr", "1.2.3.4:5060") ... route { xlog("L_NOTICE", "INVITE: F=$fu T=$tu R=$ru\n"); route("QUERY_UUID"); # <- sets $var(UUID) to l_uuid of the DB $var(request_user) = $rU; uac_reg_lookup("$var(UUID)", "$ru"); $var(request_from_user) = $rU; $rU = $var(request_user); uac_replace_from("$var(request_from_user)","sip:$var(request_from_user)@ 1.2.3.4"); t_on_failure("TRUNKAUTH"); xlog("L_NOTICE", "INVITE: F=$fu T=$tu R=$ru $avp(auser) $avp(apass)\n"); # avp "auser and apass are "<null>" if (!t_relay()) { xlog("L_ERR", "error to <$tu> from <$fu>\n"); sl_reply_error(); }; } failure_route[TRUNKAUTH] { if (t_is_canceled()) { exit; } if(t_check_status("401|407")) { # $avp(auser) = "test"; <-should be set from the l_uuid profile anyhow # $avp(apass) = "test"; $var(request_user) = $rU; if (uac_auth()) { # We do never get here since uac_auth never returns true. $rU = $var(request_user); route("FORWARD_MESSAGE"); exit; } xlog("L_NOTICE", "DAMN!!!"); } } -- Jöran Vinzens - vinzens[at]sipgate.de <vinzens(a)sipgate.de> sipgate GmbH - Gladbacher Str. 74 - 40219 Düsseldorf HRB Düsseldorf 39841 - Geschäftsführer: Thilo Salmon, Tim Mois Steuernummer: 106/5724/7147, Umsatzsteuer-ID: DE219349391 www.sipgate.de - www.sipgate.co.uk

rtpengine default set

Hi, After upgrading to Kamailio v4.4, I receive the following error on boot: May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: ERROR: rtpengine [rtpengine.c:2691]: select_rtpp_set(): script error-invalid id_set to be selected May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: ERROR: rtpengine [rtpengine.c:2691]: select_rtpp_set(): script error-invalid id_set to be selected May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: NOTICE: rtpengine [rtpengine.c:1788]: mod_init(): Default rtpp set 0 NOT found My rtpengine module config is: --- #!ifdef WITH_RTPENGINE #!subst "/RTPENGINE_SOCK/udp:127.0.0.1:5050/" modparam("rtpengine", "rtpengine_sock", "1 == RTPENGINE_SOCK") modparam("rtpengine", "rtpengine_disable_tout", 30) modparam("rtpengine", "rtpengine_tout_ms", 2000) modparam("rtpengine", "rtpengine_retr", 2) #!endif --- Furthermore, I have set_rtpengine_set("1") before every call to the rtpengine_* module function(s) in my route script.

Strictly speaking, I don't need an explicitly identified set, since I'm only using one rtpengine instance. However, I explicitly specify it because I'd like the code to be open in the future to selecting a given rtpengine relay based on some criteria. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

create packet
by zeinab 04 May '16

04 May '16

Hello, My name is Zeinab and I am using kamailio to capture sip packets. What I really want to do is to create a .pcap file so that I can open it in Wireshark. As I saw, that you are only saving the sip content in database. And to create the packet I need the entire frame. So I think there is something missing from my side. Can you help me with that? You can see in the attachment the field needed from wireshark And in sip_capture I found only this: If there is some manual were I can find the entire packets please let me know Thank you for your time and looking forward to hear from you. Best Regards, Zeinab

Kamailio 5-0 - Executing event routes in embedded languages
by Daniel-Constantin Mierla 04 May '16

04 May '16

Hello, as announced earlier this morning, most of the routing blocks can be written directly in an embedded language (right now supported being Lua and Python). The missing blocks are (most of) the event routes. The event route from tm for branch failure route is already supported, as the name has to be set via t_on_branch_failure(...). In the native configuration, event routes are executed if they are defined. Their names (as in event_route[name]) are not valid function names for the other programming languages to be used directly corresponding callback function name. I was thinking of the alternative, next are the ones I came up with, more suggestions are welcome. 1) add parameters for event route callback names, like: modparam("htable", "evrtcb_mod_init", "ksr_htable_mod_init") would define the name of the function for the alternative to event_route[htable:mod-init]. This has a benefit in speed, if the parameter is not defined, then there is no overhead in trying to execute a callback function in an embedded language. The drawback is that there is need to code a bit of C to add those parameters to the components executing event routes. 2) do a direct mapping using some translation rules, like: - prefix with ksr_ - replace ':' and '-' with underscore '_' So event_route[htable:mod-init] will have automatically the correspondent function ksr_htable_mod_init(). The drawback is that each time the even route should be called, a lookup on embedded language symbols table needs to be done to see if it exists, then execute it. There is still some C code to do, but less than adding parameters like for 1). 3) like 2), but instead of an automatic translation, keep a mapping table: struct mapping { str kname; str ename; } table[] = { str_init("htable:mod-init"), str_init("ksr_htable_mod_init"), } Adding a new event route will require adding a new record in the mapping table. The benefit is that the function name in embedded language can be selected to be whatever, with or without ties to the event_route name. Opinions?
