Hi guys, Is possible to cut change/delete display name in contact header? Does this breaks something? Cheers, Diego.

path use_received not working?
by Iskren Hadzhinedev 23 Jul '17

23 Jul '17

Hello, I have a kamailio proxy in front of FreeSWITCH. Whenever FreeSWITCH initiates the dialog (e.g. sends an INVITE), kamailio doesn't use the 'received' parameter and it forwards to the RFC1918 IP address. The initial INVITE from FreeSWITCH has the following headers: To: <sip:1001@192.168.1.200:5063> Route: <sip:1.2.3.4>;lr;received=sip:5.6.7.8:5063 Where 1.2.3.4 is the kamailio public IP and5.6.7.8 is the public IP of the UAC behind NAT. I have modparam("path", "use_received", 1) in my config file and to my understanding that should be sufficient to route to the proper IP, but kamailio keeps sending INVITEs to 192.168.1.200. Can anyone tell me what am I missing? Thanks! Kind regards, Iskren

The UDP protocol of the rtpproxy module should work with rtpengine, but not many people are using it, so it's always possible that some bugs creep in. I'll look into it anyway, but in the long run, it's much preferable to switch to the rtpengine module. Cheers ########################## Hello Richard, thank you very much for your answer. I will try to use rtpengine module. As I can see from logs, kamailio is sending correctly data to rtpengine but rtp engine failed to parse IPv6 address from SDP body. I'm sending flags to rtpengine according to the howto from link I've posted in the original post. This is the part of the config: if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB) || isbflagset(FLB_V4V6))) return; if(isbflagset(FLB_V4V6)) { if(af==INET6) { rtpproxy_manage("FAEI"); } else { rtpproxy_manage("FAIE"); } } else { if(af==INET6) { rtpproxy_manage("FAEE"); } else { rtpproxy_manage("FAII"); I'm not sure if I need to inform rtpengine that in SDP body will be IPv6 address.

kamailio 5.0 with asterisks
by Aidar Kamalov 20 Jul '17

20 Jul '17

Hello! I'm new with kamailio, so may be don't understand some basic. I'm tryin to load balance asterisk servers with kamailio and dispatcher module. My ip phones registered at kamailio, for example: [root@sipchel ~]# kamctl ul show 101 { "jsonrpc": "2.0", "result": { "AoR": "101", "Contacts": [{ "Contact": { "Address": "sip:101@192.168.2.62;line=4733c4bfa459eea", "Expires": 2953, "Q": -1, "Call-ID": "1361221648", "CSeq": 136, "User-Agent": "Linphone/3.6.1 (eXosip2/3.6.0)", "Received": "[not set]", "Path": "[not set]", "State": "CS_SYNC", "Flags": 0, "CFlags": 0, "Socket": "udp:192.168.10.54:5060", "Methods": -1, "Ruid": "uloc-596f5abc-2ce5-2", "Instance": "[not set]", "Reg-Id": 0, "Last-Keepalive": 1500530337, "Last-Modified": 1500530337 } }] }, "id": 15024 } I have realtime asterisk server. [root@sipchel ~]# kamctl dispatcher dump { "jsonrpc": "2.0", "result": { "NRSETS": 1, "RECORDS": [{ "SET": { "ID": 1, "TARGETS": [{ "DEST": { "URI": "sip:192.168.4.16", "FLAGS": "IX", "PRIORITY": 0 } }, { "DEST": { "URI": "sip:192.168.10.47", "FLAGS": "AX", "PRIORITY": 0 } }] } }] }, "id": 15087 } So I want if 101 call to 102 it will process by asterisk(for call recording and other features). Now if I call from 101 to 102 kamailio will forward to asterisk and asterisk dialplan cannot find that extesion(as expected, because it is not registed on asterisk) [kamailio] exten => _1XX,1,Dial(SIP/${EXTEN}) exten => _1XX,n,Hangup If I change dialplan to Dial(SIP/KAMAILIO/${EXTEN}) call wil return to kamailio, but kamailio send it back to asterisk... I hope I explained correctly, my English is terrible. Is my screnario proper? How this usually done? Should I forward sip registrations to asterisks?

Integration of Google Speech API V2
by Rahul MathuR 19 Jul '17

Hi, I'm trying to integrate Google cloud speech recognition v2 in it. I can get the audio recorded, have created Service key and API key but whenever I try to access it, I just get 403 access denied. I am at my wits end here. Has anybody tried it ? were you successful ? Could you please guide me how to do it ? I'll be grateful to you if this works ! -- Warm Regds. MathuRahul

Problem with IPv4-IPv6 media bridging using RTPengine
by Ismir Saljic 19 Jul '17

19 Jul '17

Hello, I've issue with bridging media between IPv4 and IPv6 clients. IPv4-IPv4 and IPv6-IPv6 calls are working without issues. I'm using kamailio 4.4.2 and configuration according to: http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 SIP signalling is working without issues,but media addresses in SDP are not rewritten correctly. The server is on amazon AWS and both kamailio and RTPengine are on the same server. RTPengine is running using these options: /usr/sbin/rtpengine --interface=privateIPv4!publicIPv4 --interface=GlobalIPv6 --listen-udp=127.0.0.1:22222 --tos=184 --pidfile=/var/run/rtpengine.pid --log-level=6 --log-facility=daemon In case of IPv4-IPv6 call, INVITE message contains correct IPv4 address but 200 OK response to the caller still contains IPv6 address of the callee in SDP body instead of IPv4 address of the server/RTPengine. This is the log during generation of the 200 OK response. Seems that RTPengine failed to parse IPv4 address from SDP body.

dns failover and branches
by Juha Heinanen 19 Jul '17

19 Jul '17

If Request-URI hostpart is a domain name with more than one SRV record, it appears that each SRV destination creates its own Kamailio branch. If branch route is set before t_relay(), it is executed only on the first SRV destination. If the first SRV destination fails, Kamailio tries automatically the second one, but any branch flags set in the branch route are lost. What is the simplest way to make Kamailio preserve the stuff set in the branch route for all SRV destinations? -- Juha

about rtpengine-[offer-answer] via-branch flag
by Juha Heinanen 18 Jul '17

18 Jul '17

rtpengine-offer function documentation tells this about via-branch flag: via-branch=... - Include the “branch” value of one of the “Via” headers in the request to the RTP proxy. Possible values are: “1” - use the first “Via” header; “2” - use the second “Via” header; “auto” - use the first “Via” header if this is a request, or the second one if this is a reply; “extra” - don't take the value from a header, but instead use the value of the “extra_id_pv” variable. This can be used to create one media session per branch on the RTP proxy. When sending a subsequent “delete” command to the RTP proxy, you can then stop just the session for a specific branch when passing the flag '1' or '2' in the “rtpengine_delete”, or stop all sessions for a call when not passing one of those two flags there. This is especially useful if you have serially forked call scenarios where the RTP proxy gets an “offer” command for a new branch, and then a “delete” command for the previous branch, which would otherwise delete the full call, breaking the subsequent “answer” for the new branch. Is the note about "serial forking" correct or should it be about "parallel forking" instead? In case of serial forking, it would not matter if the whole call is deleted, because a new offer would be issued for the next branch. Or perhaps I just don't understand the meaning of the note? -- Juha

Hello, for those new in the community as well as a reminder for the others: if you offer Kamailio-related services or products, you can get listed at: - https://www.kamailio.org/w/business-directory/ Besides that, also in the case if you just use Kamailio for RTC/VoIP services, you can add yourself in Used By directory: - https://www.kamailio.org/w/used-by/ The website has very good traffic and can increase your visibility in the market.
