Hi, The package hashes for Kamailio 5.1.4 rpms are wrong. I actually saw this happen with 5.1.3 and then somehow I think it got corrected.

DMQ with dialog: KDMQ messages being looped back to the source
by Patrick Murphy 26 Jul '18

26 Jul '18

Hi, I am using Kamailio 5.1.1 with DMQ with the following config (relevant parts) on 2 nodes. Node A: modparam("dialog", "enable_dmq", 1) modparam("dmq", "server_address", "sip:no.de.a.ip:5060") modparam("dmq", "notification_address", "sip:myvoip.local") modparam("dmq", "multi_notify", 1) Node B: modparam("dialog", "enable_dmq", 1) modparam("dmq", "server_address", "sip:no.de.b.ip:5060") modparam("dmq", "notification_address", "sip:myvoip.local") modparam("dmq", "multi_notify", 1) "myvoip.local" is a DNS A record that resolves to both the IPs of A and B. I have the dmq_handle_message(); called if method is of type "KDMQ" in the request_route. Now, in order to test it, I only sent a few calls only on node A. KDMQ messages flowed to node B and dialog state replicated. But I noticed, node B was randomly sending one of the KDMQ dialog messages back to A and receiving a 500 "Server Internal Error" back from node A... (for a subset of those calls, not all). Why would this be the case when the nodes correctly recognize their local status by the "local: 1" set as seen from dmq.list_nodes Anyone else experienced this? What could I be doing wrong? Thanks, Pat.

FreeSWITCH and OpenSIPS for a Pure SIP Video, Chat and Conference Service, ClueCon Presentation Slides
by Giovanni Maruzzelli 25 Jul '18

25 Jul '18

Hello fellow RTCers, just finished presenting about scaling videoconferencing, chat and moderation/direction controls in SIP, with web clients, deskphones, smartphone apps, server push (google fcm) via cordova and SIP.js at www.cluecon.com. Here's the slides of my presentation: http://178.79.181.125/Maruzzelli_FreeSWITCH_OpenSIPS_WebRTC_Pure_SIP_Video_… or, shorter, http://178.79.181.125/Maruzzelli_ClueCon_2018.pdf >From ClueCon blurb: FreeSWITCH and OpenSIPS for a Pure SIP Video, Chat and Conference Service On top of traditional SIP deskphones and softphones, WebRTC let us extend the reach of SIP to all browsers, and to smartphone apps that wake up with a server push. OpenSIPS has superb SIP and WebRTC support and can protect, balance and scale FreeSWITCH insuperable conferencing, video MCU, media switching/mixing, SIP SIMPLE message processing capabilities. We will see how to build and implement such a complete platform, touching both on servers and on clients. Hint: SIMPLE, the SIP Instant Messaging Protocol, can be leveraged to transport statuses, commands and chats between participants and administrators of SIP audio/video calls/conferences.

Error when using http_async_client $http_query_id var

Hello, I'm trying to build a async http call to a external server and was trying to use the $http_query_id var to identity the http call in the response route.

messages dumped in wrong order sometime
by Philip Kucheev 23 Jul '18

23 Jul '18

Hello there! Using kamailio 5.0.1 and msilo module for storing offline messages I noticed that sometimes, especially when a big number of messages dumping for one user, some of them can arrive to receiver in wrong order. Lets say we have 20 messages and the order of receiving could be next 1..18..17..19..20. That could be a reason of that ? Thanks, Philip

Forwarding to backup server
by Pali Rohár 23 Jul '18

23 Jul '18

Hello, can somebody help me how to configure Kamailio to route/forward requests to different (backup) server when Kamailio itself is not able to deliver them? I have working SIP gateway (on different host/port) which deliver received SIP messages to XMPP network and I want to achieve: Kamailio should try to send SIP messages directly to foreign SIP domains and when it fails (e.g. user not available or foreign SIP is not running), then forward message to that my SIP <--> XMPP gateway which will try to deliver it via XMPP. I guess that Kamailio should be able to configure for such custom routing/forwarding but I have not figured yet how to do it. I'm using Kamailio 4.4 with slightly modified default kamailio.cfg config. -- Pali Rohár pali.rohar(a)gmail.com

Hello Ali, ACK is sent by UAC to the Contact which is received in OK from UAS. So from my point of view you need to fix that Contact in OK on your proxy. My NATDETECT looks like: if (nat_uac_test("19")) { fix_nated_contact(); } I call it for requests and responses. Best regards.

Hi, I have a kamailio v5.0 setup where cdrs are enabled using acc module. Is there a way to enable / disable cdrs on per call basis in kamailio script? For example i want to allow cdrs only for offnet calls and disable them for onnet calls? May be a dialog flag configurable in module parameters to signal acc module whether or not to generate cdr for current dialog at the end of call?

Hello I have faced when case when private var defined as $var(json_request) is share between different SIP messages. In my case first time this var is used from registration processing route. Then var with same name is used PUBLISH messge processing. And i be able to this value defined from registration processing. I expecting that vars is not shared between threads and message handling routes for var defined as $var(name). Is that not true? How i can prevent race condition between different message processing routes when two thread simultaneously change same variable? Sergey

The problem of get_aor_hash function
by tyd 20 Jul '18

20 Jul '18

Dear all, I'm trying Kamailio 5.1.4 and IMS module. When registering to Kamailio IMS using the same ip and port for 30 users (different contact user part), the P-CSCF get the same hash number and aor value. The function get_aor_hash(_d, &_ci->via_host, _ci->via_port, _ci->via_prot) in ims_usrloc_pcscf pcontact.c seems the problem. Because hashing with host, port, prot will get the same hash value. Anyone can help this ?

Locking htable entries
by Alex Balashov 19 Jul '18

19 Jul '18

Hi, Sorry if this question has been answered before, but I'm rather puzzled as to the intent behind sht_lock() / sht_unlock(). Presumably, "thread"-safe / shm mutex locking is already implemented in htable query and mutation operations, otherwise htable would be unusable in a route script context. So what is the purpose of this higher-level lock? Is it to create a way to block config script execution in multiple processes as to serialise operations? Why would one want to do this under any ordinary circumstances? Perhaps it is a failure of my imagination...

executing python routine on demand
by Walter Martín Villalba 18 Jul '18

18 Jul '18

Hello, TL;DR How can I execute a routine in my Kamailio python module (kamailio_python.py) on demand? For example, using kamcmd from the command line. I know you can execute *app_python.reload *but I don't need to reload the whole python module, and furthermore, docs for this call say it's unstable and can even crash your kamailio instance. So my goal is to execute one single python routine on demand. https://www.kamailio.org/docs/modules/5.1.x/modules/app_python.html#app_pyt… Full explanation: I'm currently implementing OIDC token authentication for Kamailio. I have a python routine that extracts the token from a custom SIP header, and validates the token as per the OIDC spec (I'm using pyjwt plus other custom checks for this). In order to do offline validation of the token, you need the Identity Provider (IdP) Server's certificate, which I get in advance and cache in a local file on my Kamailio server. I also have an external python script which I can run to get the latest certificate from the IdP server and update it locally. The part I'm missing is how to tell Kamailio to reload the value of the certificate from the local cache, WITHOUT stopping kamailio or interrupting any sessions. This is needed in case the certificate is updated (e.g. due to expiration or compromise) on the IdP server; if you don't update it so that Kamailio can use the latest one, all token verification will fail (tokens signed by IdP server using latest private key corresponding to latest certificate, but Kamailio trying to validate the signature using the public key extracted from previous certificate -- this results in a signature error, as Kamailio needs to be using the public key corresponding to the private one that was used to sign the token). By being able to execute one single python routine on demand (e.g. using kamcmd), I can tell Kamailio to reload the certificate value from the local cache, which I just updated by running my other (external and unrelated to Kamailio software) python script. Hope this makes sense, and hopefully I can get some tips on how to achieve this. Thanks, Martín.

in-dialog requests
by Ali Taher 18 Jul '18

18 Jul '18

Hello, I'm using Kamailio as a proxy behind freeswitch to alter some packets (183 packets precisely). Here is my scenario: (---Customer---) --> ((port 5065)---Kamailio---) --> ((port5060)---Freeswitch---) --> (---Supplier---) Here is my request route : route{ if (is_method("INVITE")) { xlog("L_INFO","INSIDE request route $si \n"); insert_hf("X-AUTH-IP: $si\r\n"); } route(FWD); } reply_route { #xlog("L_INFO","INSDE reply \n"); if (status == "183") { change_reply_status(180, "Ringing"); exit; } } route[FWD] { #xlog("L_INFO","INSIDE FWD \n"); forward(X.X.X.X,5060); } Where X.X.X.X is the Freeswitch IP This script is working normally as long as the customer is sending the requests(INVITE,BYE,ACK,CANCEL..) . But when the supplier or freeswitch initiated the request , above script causes loop where the packet is bounced between kamailio and freeswitch. As I know , loose_route is used to handle such requests , but I'm not sure how to forward these packets to the customer after receiving them from freeswitch. I'm not sure also if what's I'm doing is statefull or stateless. Any help is appreciated. Thanks, Ali Taher

Kamailio dialog presence (BLF)
by Michal Škuta 18 Jul '18

18 Jul '18

Hello, I am trying make presence module work with Kamailio. Right now I am testing these modules: presence, presence_xml, presence_dialoginfo, pua and pua_dialoginfo. I had some success, the BLF is working only when the monitored extension is calling. When the monitored extension is calling, then the BLF changes its color (red). After end of the call the BLF changes color to green. My problem is when a User comes on-line then it sends SUBSCRIBE with *Event: dialog* and don't get notified of its subscribers state and BLF is not changed. I found similar problem in this mail list : https://lists.kamailio.org/pipermail/sr-users/2017-March/096314.html But is not working for me. Second question is about BLF and offline state. I can not found anything in RFC, there is no offline state, no way to turn off the BLF lamp from green to OFF. I found only this pdf from grandstream: http://www.grandstream.com/sites/default/files/Resources/GXP21x0_Eventlist_… mentioning offline state on page 8. Does anyone have experience with it?

SIP re-invite Packets
by Ali Taher 18 Jul '18

18 Jul '18

Hello, I'm using below routing logic to change the 183 reply to 180 and send it back to the origination. Noting that Kamailio is listening on 5065. route{ if (is_method("INVITE")) { xlog("L_INFO","INSIDE request route $si \n"); insert_hf("X-AUTH-IP: $si\r\n"); } route(FWD); } reply_route { #xlog("L_INFO","INSDE reply \n"); if (status == "183") { change_reply_status(180, "Ringing"); exit; } } route[FWD] { #xlog("L_INFO","INSIDE FWD \n"); forward(x.x.x.x,5060); } Below is the scenario , where the customer is sending packets to Kamailio , and Kamailio is forwarding them the supplier (with IP x.x.x.x) , then the supplier reply back to kamailio and kamailio relay the reply to the customer ----Customer---- --> ----Kamailio ---> ---Supplier--- I have a case where the supplier sends in some cases an in-dialog invite (Re-Invite) , which is considered I think as SIP-Request and thus as per above routing logic , kamailio is sending it back to the supplier , yet I need to send it to the customer. How can I solve this issue? Thanks Ali Taher

ACK Cseq incrases after 404 on uac_auth()
by Yuriy Gorlichenko 17 Jul '18

17 Jul '18

Hi. I found some additional scenario when kamailio works incorrect with ACK Cseq after succesfull auth with uac_auth but unsuccesfull call: 1.Caller via kamailio as proxy (Cseq 1) 2.Kamailio resends call to provider with Auth method (Cseq 1) 3. Provider answers 401/407 (Cseq 1) 4. Kamailio inrases Cseq and sends invite with credentians (dialog track_cseq_updates = 1, uac_auth()) (Cseq 2) 5. Provider says - 404. not found (Cseq 2) 6. Kamailio resends INVITE to another server (lets say VM). It contans not tracked yet Cseq (Cseq 1) 7. VM server says 200 (Cseq 1) 8. Kamailio resends 200 to the caller (Сseq 1) 9. Caller says ACK (Cseq 1) 10. Kamailio incrases CSeq of ACK and resends t VM server (Сseq 2) So in this case kamialio tries to track Sceq because thining that this ACK belongs to the dialog that was made to the auth server So as I see here is a misunderstanding on the dialog module Any suggestions how to avoid it or exclude resent INVITE from the dialog module tracking?

RTPEngine serial forking with early media
by Alex Balashov 16 Jul '18

16 Jul '18

Hi, I've got a scenario where call branch #1 goes to an in-call announcement server; the message is played out via unidirectional early media (183+SDP), then that branch is disposed of with a 503. A subsequent call then goes out to the real SIP provider that will ultimately answer the call. There's some trouble handling this with RTPEngine: Two subsequent calls to rtpengine_offer() in a normal request route context will result in two SDP message lumps concatenated in the second INVITE (to the provider). This can be fixed by putting the rtpengine_offer() invocations into branch routes. However, the next problem is that then the identical offer goes to the second callee with no regard for RTPEngine's internal state, so RTPEngine ends up transmitting from a different port to the one that is declared in the SDP offer, requiring NAT latching from the provider to achieve proper symmetry in the return stream. This can be fixed with: rtpengine_offer("replace-origin replace-session-connection ICE=remove via-branch=1 internal external"); And in the reply handling: rtpengine_answer("replace-origin replace-session-connection ICE=remove via-branch=2"); An alternative to using via-branch[1] is to simply delete the call before initiating branch #2: rtpengine_delete("delete-delay=0"); rtpengine_offer("replace-origin replace-session-connection ICE=remove internal external"); However, both of these lead to the problem that caller receives two distinct SDP answers on the respective branches. I am not sure offhand whether this is a protocol semantics violation. On the one hand, RFC 3261 § 13.2.1 ("Creating the Initial INVITE") says: If the initial offer is in an INVITE, the answer MUST be in a reliable non-failure message from UAS back to UAC which is correlated to that INVITE. For this specification, that is only the final 2xx response to that INVITE. That same exact answer MAY also be placed in any provisional responses sent prior to the answer. The UAC MUST treat the first session description it receives as the answer, and MUST ignore any session descriptions in subsequent responses to the initial INVITE. So, I always understood that the first answer is the final answer, absent a session-updating request cycle. On the other hand, RFC 3960 ("Early Media and Ringing Tone Generation in the Session Initiation Protocol (SIP)") Section 4 says: The application server model consists of having the UAS behave as an application server to establish early media sessions with the UAC. The UAC indicates support for the early-session disposition type (defined in [2]) using the early-session option tag. This way, UASs know that they can keep offer/answer exchanges for early media (early-session disposition type) separate from regular media (session disposition type). I take this, along with RFC 3959 Section 3, to imply an amendment to 3261 § 13.2.1, but I'm not sure. Regardless, I'm not convinced all UAs will handle this situation. So, what I would most prefer is a means of recycling the same answer port on the "back" side of RTPEngine while pivoting it on the front across branches/multiple offers. Is that possible? If so, how can it be achieved?

Encapsulate and de-encapsulate SIP traffic
by William Phillips 16 Jul '18

16 Jul '18

I have a need to encapsulate SIP traffic depending on destination and obviously de-encapsulate traffic incoming from those destinations. The approach to dealing with outbound SIP traffic seems pretty straight forward, I create an appropriate routing block that determines if I need to encap the SIP message, if I do, I forward it off to my module. The incoming traffic isn't particularly complicated, I'm just not 100% sure on the way to give that de-encapsulated SIP message back to kamailio to be processed. It looks like I can achieve this using the TM module with the uac_req_t struct and tm_bind.request but I really only see it used for SIP text messages in modules like XMPP and SMS. Is this the appropriate approach to achieve what I need? Will

Hi, I m using cent-os 6.2, kamailio-5.1.2 and openims-hss. I am using rtpengine to relay voice, but I am unable to send files or chat messages using it. I looked at rtpengine logs, it was saying unknown codec for chat and file-transfer requests. Then, I thought of using Kamailio msrp , tried but no success. Does current Kamailio IMS support file transfer? If so, please give me suggestions on doing it. -- With Best Regards, Ashok Kumar.

rtpengine/kamailio teardown method
by Abdoul Osséni 16 Jul '18

16 Jul '18

Hello all, There are some rtpengine parameters that permit to send an RPC command to kamailio in order to terminate a dialog. - timeout = xx - b2b-url = http://xxxx:xx/RPC - xmlrpc-format = 1 Each rpc command sent to Kamailio exited with status 256. By checking the code of rtpengine, I see rtpengine seems to use "teardown" method. I think Kamailio does not know this method. Can you help me please ?

UAC register
by Ben Hood 12 Jul '18

12 Jul '18

Hi, I’m wondering if there is a flag somewhere in the UAC module config that prevents remote registration from happening. It looks like I’ve loaded the uacreg table but I can’t see any REGISTER methods being sent from Kamailio to the remote peer. The remote registrants are loaded using this config: listen=udp:172.16.176.150:5060 loadmodule "db_postgres.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "cfg_rpc.so" loadmodule "counters.so" loadmodule "uac.so" modparam("uac", "reg_db_url", DBURL) modparam("uac", "reg_contact_addr", “172.16.176.150:5060") modparam("uac", "reg_db_table", "uacreg") modparam("uac", "reg_timer_interval", 10) modparam("uac", "reg_retry_interval", 10) request_route { route(RELAY); } route[RELAY] { t_on_reply("MANAGE_REPLY"); if (!t_relay()) { sl_reply_error(); } exit; } And it looks like this has been consumed by Kamailio: $ kamcmd uac.reg_dump { l_uuid: 2cc6776d-61ed-4ea1-a3ae-055f89bd4d3f l_username: 126231943099723776 l_domain: 172.16.176.150 r_username: 1000 r_domain: 172.16.176.129 realm: 172.16.176.129 auth_username: 1000 auth_password: password auth_proxy: sip:172.16.176.129:5080 expires: 0 flags: 0 diff_expires: -1531235076 timer_expires: 0 reg_init: 1531234841 reg_delay: 0 } Doing a refresh successfully reloads the uacreg data $ kamcmd uac.reg_refresh 2cc6776d-61ed-4ea1-a3ae-055f89bd4d3f I can get Kamailio to forward an OPTIONS message to the remote peer () to verify network connectivity, e.g. : $ru = "sip:1000@172.16.176.129:5080"; $fs = "udp:172.16.176.150:5060"; But Kamailio does not appear to generate REGISTER messages either after first boot or as a result of the manual refresh. This is using an instance of Kamailio 5.0.1. Should I try with a newer version? Is there a way to get extra debugging of the uac module? If I increase the debug verbosity, I get quite granular detail for the DB traffic, but the uac module doesn’t appear to emit much diagnostics. Many thanks, Ben

Kamailio, forking and multiple answer
by Marino Mileti 10 Jul '18

10 Jul '18

Hi guys, i've a Kamailio with forking scenario using addbranch technique.Now I've a problem; i know it's very very very rare but it could be possible so it's better for me to find a solution. A -> B,C,D in forking parallel mode, so B C and D rings simultaneulsy. What is happen if B anser the call, and at the same time C decline the call?It seems that, using my cfg scripts, C sends DECLINE but this message never arrive to A because it receives a 200OK of B. How I can prevent this? I would like that if DECLINE is the first message, all other answers will be ignored (first answer win). Any help or comment? ThanksMarino

TLS CRL configuration
by Amarnath Kanchivanam 10 Jul '18

10 Jul '18

Hi All, I'm trying to configured kamailio as TLS server with below configuration (tls.cfg) and TLS server is started successfully. [server:default] method = TLSv1+ verify_certificate = yes require_certificate = yes private_key = ./sip/server.key certificate = ./sip/server.crt ca_list = ./bundle.crt crl = ./sip_crl.pem verify_depth = 9 [client:default] verify_certificate = no require_certificate = no TLS connection works fine. Later i have updated the sip_crl.pem with server certificate revoked details and performed tls.reload command to load the latest update. After this I expect any TLS client trying to establish TLS connection should fail, as the client and server certificates are signed by same authority and server certificate is revoked. But the clients are able to establish TLS connection without any errors. I'm not getting any traces to confirm CRL validation has been performed before accepting the TLS connection. Any advice would be help to proceed with evaluating CRL functionality. -Amar

Delay in 100 Trying response for INVITE when the load is 70 INVITE's per sec
by vivek＠advaitamtech.com 09 Jul '18

09 Jul '18

Hi All, When we are using the kamailio to handle around 70 INVITE's per second, kamailio is sending 100 Trying with the delay of around 3-4sec for few INVITE's. How can I reduce the delay in 100 Trying? Also, I tried increasing the number of threads for SIP routing processes. This doesnt seem to help. Also tried "modparam("tm", "auto_inv_100", 0)" . This is not working. Please help. Thank you, Vivek.

Hello, In RTPEngine recording-daemon, I enabled "forward-to" option to unix_socket. All things work right, I got metadata at first, then media packets (RTP-UDP-IP). The metadata for each calls is received just at first packet, but i want to know, if i have more than one concurrent active call in RTPEngine, How can i distinct which media packet was from which call?

RFC: database unsigned number types
by Daniel-Constantin Mierla 07 Jul '18

07 Jul '18

Hello, starting here a discussion about an issue with the database API and signed/unsigned number type to see how to address it. So far, the database API supported only signed types for numbers, respectively DB1_INT (int in c) and DB1_BIGINT (long long in c). However, many database table columns are defined as UNSIGNED INT or UNSIGNED BIGINT. The database connector modules are mapping UNSIGED values retrieved from database over signed fields in DB API structure. The other way around is done as well: signed values are the inserted in the unsigned columns. There is no issue if the value in C is a positive number, however, if the value goes over MAX_UINT/2 (over 2147483647), it becomes negative and inserting the value in database results in an exception and 0 being stored instead. So far, I guess the issue was rarely exposed, if at all, because no report on it, even these data types for DB1 are since the SER project was started in 2001. As I looked at database definition schema, most of unsigned columns are for internal flags or ids (e.g., lcr_id), where I guess no large values were used or needed so far. However, it can bite at any time and needs to be addressed. So far, two solutions come in mind: 1) drop using UNSIGNED INT for those db columns, use only INT and do unsigned cast in the C code when reading and cast to int when writing. 2) update the db connector modules to support unsigned types -- I added support for them in DB API, but each db_* module has to be updated. The also each module that uses UNSIGNED DB columns must be updated 1) should be simpler, 2) more work but better in long term Any other ideas? Which of the options you prefer to go for? Not to forget: somehow related, probably we have to switch from int to long for PV number values, otherwise timestamp variables can go negative once unix timestamp approaches MAX_UINT/2 (still plenty of time, but should not be delayed for long ...).

rtpengine installation dependencies

Also, If someone can help me how to resolve dependency for libbcg729-dev too. Any pointer or hint or link to some installation guide would be more than welcome. Br, Aqs.

Video call recording and mobile push notifications
by Jeremy Renner 05 Jul '18

05 Jul '18

Hi, I would like to setup up my SIP server / PBX for my business, now we have some candidates: 1. Open source solution: - Asterisk PBX, - Freeswitch PBX - Kamailio - OpenSIPS 2. Business solution: - Brekeke PBX(https://www.brekeke.com - Vodia PBX(https://www.vodia.com) - 3CX PBX(https://www.3cx.com) - PortSIP PBX(https://www.portsip.com/portsip-pbx) *Below features are mandatory for our project:* - Video call recording (For the finance industry, the video recording is necessary) - Push notifications for mobile app - Multi-tenant support - Both Linux and Windows support (at 1st stage, we would like to run it on Windows server and migrate it to Linux server in the future if users increased), the Linux support is required, the Windows support is preferred. We have some questions: 1. Does the the Kamailio can works as a PBX ? 2. If yes, does the Kamailio support push notifications and video recording ? 3. Does the Kamailio can works for Multi-tenant ? 4. Does Kamailio support Windows ? So far according to our research, with the business solution: - The Vodia PBX, PortSIP PBX and brrekeke all are support Multi-tenant, the 3CX is not. - The 3CX and PortSIP support push notifications, - The PortSIP also provide client SDK, with 3CX we only see the 3CX provide client apps, does 3CX has client SDK provided ? - It's seems all these PBX are support video recording ? - The PortSIP PBX and 3CX both support Linux. Please help me to make the decision, base on your experiences, which one (open source or business solution) is good to us ? I'm really new to VoIP... Thanks in advance. Best regards,

Re-write From URI Domain ($fd) with source IP or relayed message
by Marrold 04 Jul '18

04 Jul '18

Hi All, For interoperability reasons I need to re-write the From URI Domain ($fd) in requests proxied by Kamailio to the source IP (socket) that Kamailio will send them via. I have experimented with onsend_route and can successfully discover the snd_ip, however it seems I am unable to rewrite the $fd, presumably because I am too late in the logic. Is this possible? I can hardcode IPs if required but would rather keep it dynamic if I can. Thanks in advance, Matthew

Kamailio Anycast
by Mike Little 03 Jul '18

03 Jul '18

Hello, Sorry if this has already been answered but can Kamailio be configured to support clustering and use Anycast? We are looking to use Kamailio as a front end to Asterisk as the registar and presence server. If this is supported, are there any documents that explain how to configure this type of setup? Thanks!

IMS usage of Kamailio
by Akib Sayyed 03 Jul '18

03 Jul '18

Dear All I am willing to try Kamailio as IMS. before i try i would like to know following points - in Kamailio i see diameter support and authentication I-CSCF, P-CSCF, S-CSCF charging, QOS, ISC implemented but what about TAS do i need TAS seperately - I see that there is HOW-TO wiki , in how to wiki you are using FHoSS as HSS , can we use commercial/any other hss (afaik its using diameter so any HSS will do)? - Is there any configuration online available kamailio as IMS? - Are all IMS modules of Kamailio can be installed on one server or need each module on same machine (i am using IMS only for testing 1 or 2 calls at a time)

Having trouble getting presence working with Polycom VVX phones
by Justin Foley 03 Jul '18

03 Jul '18

Hey everyone. I've set up a kamailio server on a local dev box and running the phones on the same subnet as it to avoid any NAT issues. Seems to work fine, phones register & can call eachother and hear voice but the issue I'm running into is I can't seem to get presence to work. I've enabled it in the kamailio.cfg file with #!WITH_PRESENCE but if I go into "do not disturb" or try to call on phone1, it's not indicated on phone2. Also running ngrep on port 5060, I'm not seeing the anything regarding presence being sent over the SIP protocol.

Hi community, So I'm running 4.1.5 Kam version and I wanted to print out $rs variable. It printed out <null> right after the 183 session. Should it print something?

Auth and default kami config
by yu＠yu-boot.ru 03 Jul '18

03 Jul '18

Hello. Have a question on auth and default kamailio.cfg. Default behavior of kamailio on auth is: Auth initial requests, delete auth headers before forwarding to next hop. In-dialog requests are forwarded "as-is" so all auth related info is propagated to uplinks or just another Kami users. How should it be done correctly or "kamailio-way"? As for now, I just delete auth headers for all in-dialog requests, but I'm not sure it is correct. I looked how it works on softswitches like Yate. Registers and initial Invites are authenticated, ACK is not authenticated, but all other requests like reINVITE and BYE are. How is should be done? Thanks. -- sent from myMail for Android

kamailio with kannel
by eyas barhouk 02 Jul '18

02 Jul '18

hello dears , i'm trying to use "http_client" module to post SMS from kamailio to kannel using the following configuration : ....... modparam("http_client", "httpcon", "kannel=>http://username:password@127.0.0.1:443") .......... ......... http_connect("kannel","cgi-bin/sendsms?user=username&pass=password&charset=utf-16&coding=2&from=$avp(from)&to=$avp(to)&text=$(avp(text){s.escape.user})","$var(result)"); ....... And this test success for English characters & phrases, but when i'm trying to send Arabic or Chinese characters it only success if the content of the SMS only has one word. in other-word i mean when i'm trying to send more than one Arabic word with a space between each word it reply with HTTP error code 400. so do you have any ideas about this problem ??

Should I ignore Route header in ACK?
by Yuriy Gorlichenko 02 Jul '18

02 Jul '18

Hi I know that this is not question too much close to the kamialio users but mostly losed to the RFC specifiacations but this community looks like pretty much close to it that is why I want to ask this question here, that's why sorry and thanks for help in this question: I have a situation when provider sends me 200 response with Request-Route header and changed contact header: Means response comes from 1.1.1.1:5060 Request-Route contains: 1.1.1.1:5060 But Contact contains: 1.1.1.1:5061 My ACK (handled by kamailio) goes to the 1.1.1.1:5060 as it setted up at the Route Hedaer of ACK (because of Request-Route) but provider says me that i should use Contact for the ACK I was surprised because of https://tools.ietf.org/html/rfc3261#section-12.2.1.1 and https://tools.ietf.org/html/rfc3261#section-8.1.2 Says that I should use Route header for reaching destination But I was surprised second time when tested this scenario with FreeSwitch and another softphone (as UA) because of it both sends ACK to the based on Contact address and ignores Route I just wanna ask if I missed some scenario in the RFC when it is described to ignore Route header for the UA (I know that I use kamailio on my case as proxy server but should understand finally who should make changes with packet handling) Thanks one more time for the resonses and sorry one more time for the goal of this question that belongs to the kamailio just partially

Fwd: Video call recording and mobile push notifications
by Jeremy Renner 01 Jul '18

01 Jul '18

Hi, I would like to setup up my SIP server / PBX for my business, now we have some candidates: 1. Open source solution: - Asterisk PBX, - Freeswitch PBX - Kamailio - OpenSIPS 2. Business solution: - Brekeke PBX(https://www.brekeke.com - Vodia PBX(https://www.vodia.com) - 3CX PBX(https://www.3cx.com) - PortSIP PBX(https://www.portsip.com/portsip-pbx) *Below features are mandatory for our project:* - Video call recording (For the finance industry, the video recording is necessary) - Push notifications for mobile app - Multi-tenant support - Both Linux and Windows support (at 1st stage, we would like to run it on Windows server and migrate it to Linux server in the future if users increased), the Linux support is required, the Windows support is preferred. We have some questions: 1. Does the the Kamailio can works as a PBX ? 2. If yes, does the Kamailio support push notifications and video recording ? 3. Does the Kamailio can works for Multi-tenant ? 4. Does Kamailio support Windows ? So far according to our research, with the business solution: - The Vodia PBX, PortSIP PBX and brrekeke all are support Multi-tenant, the 3CX is not. - The 3CX and PortSIP support push notifications, - The PortSIP also provide client SDK, with 3CX we only see the 3CX provide client apps, does 3CX has client SDK provided ? - It's seems all these PBX are support video recording ? - The PortSIP PBX and 3CX both support Linux. Please help me to make the decision, base on your experiences, which one (open source or business solution) is good to us ? I'm really new to VoIP... Thanks in advance. Best regards,

linphone & presence_xml ERROR
by Pali Rohár 01 Jul '18

01 Jul '18

Hi! I'm using linphone 3.6.1 as SIP client and Kamailio 4.4.4 as proxy server and registrar. And every time I try to change online status (presence) in linphone client, I see following error messages in kamailio server log: ERROR: presence_xml [add_events.c:167]: xml_publ_handl(): bad body format ERROR: presence [publish.c:443]: handle_publish(): in event specific publish handling ERROR: tm [t_reply.c:533]: _reply_light(): ERROR: _reply_light: can't generate 500 reply when a final 415 was sent out ERROR: sl [sl.c:269]: send_reply(): failed to reply stateful (tm) ERROR: presence [utils_func.c:146]: send_error_reply(): sending 500 Server Internal Error reply ERROR: presence [publish.c:492]: handle_publish(): failed to send error reply So it looks like kamailio is not able to parse presence change which is linphone doing.

Maybe it helps you. Any idea why kamailio refuse presence update and reports those error into error log? Or is there any special setting which is needed for linphone or other SIP clients for online status / presence support? -- Pali Rohár pali.rohar(a)gmail.com

dovecot authentication
by Pali Rohár 30 Jun '18

30 Jun '18

Hi! Is there any module or configuration how to use dovecot SASL authentication in Kamailio? Dovecot exports unix socket (or tcp on localhost) for authentication service and lot of server applications can be configured to use it (e.g. postfix, prosody, ...) to have one central place of user and authentication database. It supports also strong authentication schemas like SCRAM-SHA, but also plain text password or DIGEST-MD5. In SIP is used DIGEST-MD5 therefore it could be suitable also for SIP and Kamailio. -- Pali Rohár pali.rohar(a)gmail.com

Relevant development links
by Amauri Oliveira 28 Jun '18

28 Jun '18

Hello. I'm new to Kamailio perhaps I've seen it in actions at AirBNB. I'm starting the journey as a new developer who wants to grab Kamailio and build something. I would like to check if you could provide the most relevant links for a beginner also with some samples. I noticed the abundance of modules perhaps I would like to see what people are doing with it. Best Regards, Amauri.

Fwd: Understanding is_first_hop() and how it handles in-dialog replies
by Joel Serrano 28 Jun '18

28 Jun '18

Hi guys, I'm having an issue which I have narrowed down to is_first_hop(), I can apply a workaround, but I don't know if I'm doing it correctly or if my problem is caused by misconfiguration of anything. Let's say we have the following flow: Client (NAT) TLS -> Kamailio1 (only Public IP) UDP -> Kamailio2 (only Public IP) UDP -> FreeSWITCH (only Public IP). Regarding this setup, let's focus only on Kamailio1. And for the sake of a clear example, I have done a little draw.io diagram: >From the above flow, let's stick to the *200 OK* that Kam1 is going to receive from Kam2. (marked in *blue* in the screenshot). First 200 OK (replying to initial INVITE): SIP/2.0 200 OK Via: SIP/2.0/UDP KAM1_PUB_IP;rport=5060;branch=z9hG4bK1e2b. e1307b519c9b5f0015343e13f35aeace.0;i=3 Via: SIP/2.0/TLS [2607:fb90:489b:6e13:85f8:596b:b86b:c831]:54744; received=172.58.17.149;branch=z9hG4bK.jmXSnh-7x;rpo =43842 Record-Route: <sip:KAM2_PUB_IP;lr=on;ftag=7vidaJ3Hw;did=36e.d441> Record-Route: <sip:KAM1_PUB_IP;r2=on;lr=on;ftag=7vidaJ3Hw;did=36e.a792; nat=yes> Record-Route: <sip:KAM1_PUB_FQDN:443;transport=tls;r2=on;lr=on; ftag=7vidaJ3Hw;did=36e.a792;nat=yes> From: "Joel Test 1" <sip:8bd2a0aba14541789bb7269800646458@MY_DOMAIN >;tag=7vidaJ3Hw To: "Joel Test 2" <sip:e78f2617b0d345d3bdb7b6780ece903c@MY_DOMAIN>;tag= vceg6N0m5ypHa Call-ID: 3ezoQGF1kp CSeq: 21 INVITE Contact: <sip:e78f2617b0d345d3bdb7b6780ece903c@FS_PUB_IP:6061;transport=udp> User-Agent: TP MEDIA 2.0 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Allow-Events: talk, hold, conference, refer Content-Type: application/sdp Content-Disposition: session Content-Length: 358 Remote-Party-ID: "e78f2617b0d345d3bdb7b6780ece903c" <sip: e78f2617b0d345d3bdb7b6780ece903c@MY_DOMAIN>;party=calling; privacy=off;screen=no v=0 o=TP 1529576021 1529576022 IN IP4 FS_PUB_IP s=TP c=IN IP4 FS_PUB_IP t=0 0 m=audio 25484 RTP/AVP 96 101 a=rtpmap:96 opus/48000/2 a=fmtp:96 useinbandfec=1; maxplaybackrate=8000; sprop-maxcapturerate=8000 a=rtpmap:101 telephone-event/48000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=rtcp:25485 IN IP4 FS_PUB_IP Second 200 OK (replying to in-dialog INVITE with updated SDP): SIP/2.0 200 OK Via: SIP/2.0/UDP KAM1_PUB_IP;rport=5060;branch=z9hG4bKed2b. 0006a6a159e800129a62b4415fdd64e6.0;i=7 Via: SIP/2.0/TLS 192.168.30.63:54752;received=A.B.C.D;branch=z9hG4bK. iKO2iYIgK;rport=27819 From: "Joel Test 1" <sip:8bd2a0aba14541789bb7269800646458@MY_DOMAIN >;tag=7vidaJ3Hw To: "Joel Test 2" <sip:e78f2617b0d345d3bdb7b6780ece903c@MY_DOMAIN>;tag= vceg6N0m5ypHa Call-ID: 3ezoQGF1kp CSeq: 22 INVITE Contact: <sip:e78f2617b0d345d3bdb7b6780ece903c@FS_PUB_IP:6061;transport=udp> User-Agent: TP MEDIA 2.0 Accept: application/sdp Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Supported: timer, path, replaces Content-Type: application/sdp Content-Disposition: session Content-Length: 358 v=0 o=TP 1529576021 1529576022 IN IP4 FS_PUB_IP s=TP c=IN IP4 FS_PUB_IP t=0 0 m=audio 25484 RTP/AVP 96 101 a=rtpmap:96 opus/48000/2 a=fmtp:96 useinbandfec=1; maxplaybackrate=8000; sprop-maxcapturerate=8000 a=rtpmap:101 telephone-event/48000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=rtcp:25485 IN IP4 FS_PUB_IP Now here comes the problem, I have the following in my kam1 config: route[NATMANAGE] { ... if (is_reply()) { if (isbflagset(FLB_NATB)) { if (is_first_hop()) { fix_nated_contact(); } } } ... } So, on the first 200 OK, when it reaches that part of the config: 1- is_reply() -> OK 2- isbflagset(FLB_NATB) -> OK (because on the initial request NAT was detected blablabla....) 3- is_first_hop() -> FAIL fix_nated_contact() is NOT applied. (This is the correct and the expected behavior). Now, on the second 200 OK, again in that part of the config: 1- is_reply() -> OK 2- isbflagset(FLB_NATB) -> OK 3-is_first_hop() -> OK fix_nated_contact() is applied, thus the contact will be changed, and the client will send the ACK with incorrect information leading to another set of issues... >From the docs: https://www.kamailio.org/docs/modules/5.1.x/ modules/siputils.html#siputils.f.is_first_hop *4.30. is_first_hop()* *The function returns true if the proxy is first hop after the original sender. For incoming SIP requests, it means there is only one Via header. For incoming SIP replies, it means that top Record-Route URI is 'myself' and source address is not matching it (to avoid detecting in case of local loops). Note that it does not detect spirals, which can have the condition for replies true also in the case of additional SIP reply receival.* So going back to the examples: first 200 OK: 1- "top Record-Route URI is 'myself' -> FAIL So we we are NOT the first hop, we do nothing and forward the reply to the client. second 200 OK: 1- "top Record-Route URI is 'myself' -> No record-route headers are present, so we enter the is_first_hop() condition and modify the contact with fix_nated_contact(). Now to the real topic, I have a workaround as: ... if (is_reply()) { if (isbflagset(FLB_NATB)) { if (is_first_hop()) { if (!ds_is_from_list()) { # <-- Check to see if the reply is coming from our internal servers fix_nated_contact(); } } } } ... And that is working correctly, but I would like to understand the reasons. I hope I have explained myself correctly, otherwise it's impossible to get to the point of my questions: 1- Is it correct for is_first_hop() to detect the second 200 OK as a first hop when it isn't? the behavior matches the documentation, so I don't know. If we stick to the check of the headers etc etc, it's working as described, if we stick to the concept of kam1 being actually being the first hop of that 200OK, then the check would need another condition to exclude the 200 OK (or better, the replies) of an in-dialog INVITE. 2- Do you guys consider the workaround something reasonable? Under my opinion I would like to not have to add that, but I also don't know. 3- Am I missing something super standard that avoids all of this? I'm starting to go crazy trying and comparing different things to get to understand this and I want to make sure it's not just a is_first_hop() bug? Sorry for such a long email, but I think that describing the scenario and flow was required. Any input is more than welcome! Thanks! Joel.

Question on the new Kamailio v5.x Releases
by Ginhoux, Patrick 27 Jun '18

27 Jun '18

Hi, I always read your email regarding new stable releases. I am currently working on a project upgrade of multiples servers to the most recent OS (Windows, RedHat) and middleware. In this project, I have upgraded SIP Proxies server running on old version of Kamailio, to the 5.0.1 release (over RedHat 7.4). Effort to make that upgrade and tests have been done with success in the last months. So considering to upgrade to the 5.0.7 or 5.1.4 would be a subsequent work I need to evaluate. I could read all the release notes, but it is also a big challenge to determine if fixes are interesting for me. Based on your experience, is there particular cases, fixed in the new release I need to pay attention? Any comments are welcome. Regards Patrick GINHOUX

Hello, I thought of start planning the next IRC devel meeting, it is quite some time since the last one with a busy spring for most of us. Among the topics to be approached would be the roadmap to the next major release, then discuss what else we can do for or with the project. My proposal as a date is Tuesday, June 27, at 14:00 UTC -- I created a page for it: - https://www.kamailio.org/wiki/devel/irc-meetings/2018a List yourself if you can participate or you prefer a different date, as well as add new topics that you consider they should be approached. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference -- www.kamailioworld.com

Kamailio installation
by Danny Roberts 23 Jun '18

Newbie: TOPOH in SBC/Proxy scenario regarding To-header
by Kevin Olbrich 21 Jun '18

21 Jun '18

Hi! I set up a proxy in front of an asterisk server to handle registration and similar. This setup needs topology hiding. I enabled and configured TOPOH which is working well. The only header which leaks network details is "To". It lists the proxys internal IP. Sure, a proxy should not alter the To and I am investigating if this can be changed in asterisk but is it even possible? Kind regards Kevin

Kamailio + FreeSwitch + WebRTC
by Emanuel Gianico 21 Jun '18

21 Jun '18

Hi everybody, I followed this tutorial https://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc#kamail… And it works fantastic! The next step was to add WebRTC support, so I added WebSockets module to enable web clients to register on kamailio. It works flawlessly and webphone clients register OK! (Followed this http://nil.uniza.sk/sip/kamailio/configuring-kamailio-4x-websocket ) Now, when I call from a softphone (eyeBeam) to the web client (jssip) the other party reach okay, rings okay, but when I pickup de call (from the web client), the softphone goes directly to the VoiceMail. >From the logs I see the jssip throw this error: "Failed to set remote offer sdp: Called with SDP without DTLS fingerprint." I would like to avoid RTPEngine, because from what I understand, FreeSwitch can handle the media part. Can somebody please have the kindness to guide me on how to enable webrtc between Kamailio and FreeSwitch? If somebody needs to see the "kamailio.cfg" please let me know, and i would upload the file to a gist. Cheers, Emanuel.

21 Jun '18

Hello, I am considering to release Kamailio v5.0.7, out of git branch 5.0, sometime next week, likely to happen on Thursday, June 21. As usual, if there is any issue not reported yet on github, do it a soon as possible to have a chance to investigate.

Kamailio 5.1.2 and Module PDB: pdb_query returns always 0
by Stefan Rüetschli 20 Jun '18

20 Jun '18

Hi I have here Kamailio 5.1.2 with PDB Module. I use the documented function from PDB-Module as follows: pdb_query("$rU", "$avp(i:82)"); xlog("L_INFO","PDB result $rU: $avp(i:82)\n"); The problem is, that $avp(i:82) is always 0. If I test the PDB-Server, with "pdbt -r localhost:5574 query <phonenumber>" I get a valid response. I use this already with Kamailio 4.3.6 and there it is working. https://kamailio.org/docs/modules/5.1.x/modules/pdb.html Any ideas? Thanks & regards Stefan

20 Jun '18

Dear sir, I'm using Kamailio 4.4.0 and 5.1.4 IMS module. During using SIPp 3000 subscriber register testing, after enabling PCSCF DB URL function, the contents of 3000 subscribers on PCSCF location table are the same. Using the same IP address and UDP port of 3000 SIPp REGISTER message seems to be the problem. Anyone can help me? Thanks a lot.

KEMI routing script Python exceptions with empty traceback
by Michael Loughrey 19 Jun '18

19 Jun '18

Hi All, I'm using app_python with a KEMI Python routing script. I have been getting occasional Python exception error logs : kamailio[2242]: 8(2253) ERROR: app_python [python_support.c:150]: python_handle_exception(): python_exec2: Unhandled exception in the Python code: kamailio[2242]: TypeError: an integer is required The scripts seems to function without an issue but these error logs appear fairly frequently, always with an empty Python stack trace. I am running Kamailio 5.1 on a Debian 9 system and using Python 2.7 : >>:/usr/local/etc/kamailio# python --version Python 2.7.13 >>:/usr/local/etc/kamailio# kamailio -v version: kamailio 5.1.4 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 18:56:43 Jun 8 2018 with gcc 6.3.0 I have also tried using a Kamailio load built from the master branch (commit f8b8cecb) which gives enhanced exception logging identifying the function an exception occurs within and parameters. I see this occurring in different parts of the routing script e.g. from script def ksr_onsend_route(self,msg): KSR.xlog.xdbg("ONSEND_ROUTE fs=[$fs] $mb\n"); return 1; an exception is reported within ksr_onsend_route() even when the log level is info. Changing log to xlog.xinfo, the log is seen to be sent to syslog but again the exception is reported. These exceptions are always "TypeError: an integer is required" but don't seem related to the Python script. Here is an example of the log with a patch applied to to Kamailio 5.1 to show the function the exception is reported within. kamailio[14092]: 6(14103) ERROR: app_python [python_support.c:156]: python_handle_exception(): apy_exec: ksr_reply_route((null)): Unhandled exception in the Python code: kamailio[14092]: TypeError: an integer is required . . . kamailio[14092]: 22(14119) INFO: <script>: ONSEND_ROUTE fs=[udp: 10.0.31.126:5080] ACK sip:10008@media.test.io:5061;transport=TLS SIP/2.0 . . . . kamailio[14092]: 22(14119) ERROR: app_python [python_support.c:156]: python_handle_exception(): apy_exec: ksr_onsend_route((null)): Unhandled exception in the Python code: kamailio[14092]: TypeError: an integer is required Has anyone got an idea what can be causing these exceptions and how to avoid them? Currently I have simply patched the load to drop the level of this log to debug when such an exception occurs with an empty traceback as they seem spurious. Cheers Mike

Installing RTPengine on CentOS 7
by Francisco Valentin Vinagrero 19 Jun '18

19 Jun '18

Hi, I'm trying to install RTPengine in the same machine as I have Kamailio, running CentOS 7, but there are a few dependencies that yum cannot seem to resolve and I that cannot find anywhere else. As soon as I try to build the daemon it produces these errors: make[1]: Leaving directory `/usr/local/src/rtpengine/daemon' Failed build with ../lib/fix_frame_channel_layout-01.h Trying build with ../lib/fix_frame_channel_layout-02.h make[1]: Entering directory `/usr/local/src/rtpengine/daemon' rm -f "resample.c" echo '/******** GENERATED FILE ********/' > "resample.c" cat ../lib/"resample.c" >> "resample.c" Package libevent_pthreads was not found in the pkg-config search path. Perhaps you should add the directory containing `libevent_pthreads.pc' to the PKG_CONFIG_PATH environment variable No package 'libevent_pthreads' found Package libavcodec was not found in the pkg-config search path. Perhaps you should add the directory containing `libavcodec.pc' to the PKG_CONFIG_PATH environment variable No package 'libavcodec' found Package libavformat was not found in the pkg-config search path. Perhaps you should add the directory containing `libavformat.pc' to the PKG_CONFIG_PATH environment variable No package 'libavformat' found Package libavutil was not found in the pkg-config search path. Perhaps you should add the directory containing `libavutil.pc' to the PKG_CONFIG_PATH environment variable No package 'libavutil' found Package libswresample was not found in the pkg-config search path. Perhaps you should add the directory containing `libswresample.pc' to the PKG_CONFIG_PATH environment variable No package 'libswresample' found Package libavfilter was not found in the pkg-config search path. Perhaps you should add the directory containing `libavfilter.pc' to the PKG_CONFIG_PATH environment variable No package 'libavfilter' found So, in the end, at least 'libevent_pthreads','libavcodec', 'libavformat', 'libavutil', 'libswresample' and 'libavfilter' are missing. Trying to install them one by one with yum fails because it cannot find these packages for CentOs 7. Can anyone point me to a solution for this? Thanks, Francisco.

Re: [SR-Users] Textops Regex
by Duarte Rocha 19 Jun '18

19 Jun '18

You're right, it is application/sdp and the back slash works as escape character. However, a new problem came. I'm using this, since someone upstream is adding \r\n to a part of the body : replace_body_all("application\/sdp\r\n\r\n", "application/sdp\r\n"); The regex finds the application/sdp just right, but doesn't replace everything. So, as a final result i get applicationapplication\sdp\r\n. Is this intended? Thanks for your help

Hello, I'm trying to configure Kamailio 5.1 like "presence" server. Pretty much with default settings of kamailio: # ----- presence params ----- modparam("presence", "db_url", DBURL) ;modparam("presence", "server_address", "sip:10.0.6.226:5060" ) modparam("presence", "send_fast_notify", 0) modparam("presence", "db_update_period", 20) modparam("presence", "clean_period", 40) modparam("presence", "subs_db_mode", 2) modparam("presence", "fetch_rows", 1000) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) # ----- presence_dialoginfo params ----- modparam("presence_dialoginfo", "force_single_dialog", 0) # ----- pua params ----- modparam("pua", "db_url", DBURL) modparam("pua", "db_mode", 2) modparam("pua", "update_period", 60) modparam("pua", "dlginfo_increase_version", 0) modparam("pua", "reginfo_increase_version", 0) modparam("pua", "check_remote_contact", 1) modparam("pua", "fetch_rows", 1000) # ----- pua_dialoginfo params ----- modparam("pua_dialoginfo", "include_callid", 1) modparam("pua_dialoginfo", "send_publish_flag", FLT_DLGINFO) modparam("pua_dialoginfo", "caller_confirmed", 0) modparam("pua_dialoginfo", "include_tags", 1) modparam("pua_dialoginfo", "override_lifetime", 124) # ----- dialog params ----- modparam("dialog", "db_url", DBURL) modparam("dialog", "enable_stats", 1) modparam("dialog", "db_mode", 1) modparam("dialog", "dlg_flag", FLT_DLG) And when UDP transport is using, everything works perfect. But when TCP is using (only "listen: tcp:IP:5060" is set) NOTIFY is not send. When "listen: tcp:IP:5060" and "listen: udp:IP:5060" I receive NOTIFY but through UDP.

Timer child process loosing MySQL connections
by Tobias Lindgren 19 Jun '18

19 Jun '18

Hi all! Having an issue with MySQL db connections being dropped in a system running 4.4.7. We're using db_mysql and db_cluster modules setup a cluster connecting two different DB servers. We have two cluster connections, one for acc and one for "other queries". One DB (A) is on the same network, another DB (B) is on another network. The default DB connection is for the remote server B. Auto reconnect is enabled. The specific issue seen is that the "timer" child process looses/drops both connections to DB A and B. Looking at the output from lsof when this happens, the connections usually does not both drop connections for A and B at the same time. Sometimes the connections keep up for ~24h, sometimes for 10 minutes, but normally the problem re-occurs every 6 hours or so. We're seeing this problem on two Kamailio servers, both handling fairly high amount of calls. None of the other Kamailio child processes seems to get their connections dropped, only the "timer" process. To solve this we need to restart Kamailio. Lately I've added the timer.so module to make a simple query on each cluster connection each 10 seconds.

Have been trying to debug this for some time now but I'm running out of ideas. Do you have any ideas on what I could look for? Any idea on why it's just the timer-process? Kind regards, /Tobias

Hi, I am trying to configure kamailio to play early media and i am using rtpproxy_stream2uac(), but the audio file plays only after the call is connected. How to use rtpproxy_stream2uac() to play only the early media.
