Can MSRP module relay to multiple destinations?
by Sefa Cebe 31 Mar '20

31 Mar '20

Hello, I'm using Kamailio MSRP module as a MSRP relay, It works successfully when I send one-to-one MSRP messages. I am having trouble while sending msrp messages to multiple receivers. My question is that can I use this module to forward msrp messages not just one receiver, but multiple receivers? Can this module be used like MSRP switch? Thanks in advance.

Kamailio breaks RFC's 'Contact Header'
by Edward Romanenco 31 Mar '20

31 Mar '20

Description I'm running Kamailio 5.2.0, whenever I relay an invite via Kamailio, my original contact header is changed from the original: sip:+XXXXXXXXX@YYY.YYY.YYY.YYYY:5060;transport=udp;gw=netvision To sip:YYY.YYY.YYY.YYY;line=sr-.n274i0TMfsHMcCAlVyAMV5IlgCXvV8n4edQlgIUlgKQ4Vk74gI1LmZ69NM79FZAR3JC.cDNLfHUj3Wnp3MP9nd*. Even when I set it correctly on my route, using: remove_hf("Contact"); append_hf("Contact: sip:$tU@YYY.YYY.YYY.YYY:5060;transport=udp;gw=netvision\r\n", "Contact"); It still ends up being modified. What can I do to keep the contact header as it is? SIP Traffic U YYY.YYY.YYY.YYY:5060 -> 81.24.193.248:5060 INVITE sip:+442033202609@81.24.193.248:5060 SIP/2.0.

Re: [SR-Users] How to correctly answer a PnP-SUBSCRIBE message
by Jan-Hendrik Dörner 31 Mar '20

Hello Daniel, thank you for your reply. I changed the line mentioned to t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "$su", "192.168.1.156","Call-ID: $hdr(Call-ID)\r\nSubscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-{mac} <http://server.conf/settings-%7Bmac%7D>"); the result is: 3) Call-ID is fine now ; Problem solved :-) 1) The Via IP is now changed to the IP and port of the server, but not to the IP of the phone. 2) The sending interface / IP is not correct: It now sends _only_ from the wrong IP !! As a result, it repeats sending the NOTIFY-message over and over again since the message does not get to the phone ...

How to correctly answer a PnP-SUBSCRIBE message
by Jan-Hendrik Dörner 30 Mar '20

30 Mar '20

Hallo, several telephones send a SIP-multicast SUBSCRIBE message to address 224.0.1.75 if they have no settings-URL configured and receive none over DHCP. So I configure my kamailio server, to respond to that multicast-request. But: Although mine is working, I do feel it could be improved, since the NOTIFY packet send out is not quite as it should be … Here is what I did (the 172.23.56.1 is my voip-vlan-address) listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060 mcast="eth0" listen=udp:224.0.1.75:5060 …. if ($Ri == "224.0.1.75"){ if(is_method("SUBSCRIBE")){ xlog("L_INFO", "Received pnp-event from IP $si from User-Agent $hdr(User-Agent) und User $fU\r\n" ); sl_send_reply("200", "OK"); t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "", "","Subscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-{mac}"); }else { xlog("L_INFO", "Drop message $rm from pnp-Interface \r\n" ); } exit; } And here are the SIP-packets I see on my server (192.168.1.156) coming from my snom-phone (192.168.1.152). My problems with the NOTIFY -packets are: 1) How do I set the Via parameters to be the same as in the OK-reply? 2) How do I send out the NOTIFY only via the 192.168.1.156 network interface? 3) May I send out the NOTIFY with the Call-ID from the SUBSCRIBE message? How? Any help is highly appreciated Jan-Hendrik # U 192.168.1.152:58714 -> 224.0.1.75:5060 #258 SUBSCRIBE sip:MAC%3a0004137120D8@lan SIP/2.0. Via: SIP/2.0/UDP 192.168.1.152:58714;rport.

I noticed that in 5.3 and master setting $du in branch route has no effect. It works fine in 5.2 using exactly the same config. -- Juha

Problem faced when Using Kamaiio as Session Refresher
by harneet singh 30 Mar '20

30 Mar '20

Hi, I am fairly new to Kamailio and had a question regarding how to use Kamailio to enable Session refresh functionality when Kamailio is acting as Sip Stateful Proxy. Kamailio Version used: *5.3.2* with *Call Load based routing* using the *dispatcher *module. * From what i understand from the documentation, Kamailio will probably not be acting as a session refresher, but Kamailio can tear down the call in case session refresh is negotiated, between the caller and the callee(via Kamailio Sip Proxy), and no message exchange happens in the duration set in Session-Expires header. *Is my understanding correct?* ** *I believe the above functionality is possible by using the *sst* and *dialog* module. I have set the same according to the documentation but I keep getting the following error: "dialog [dlg_handlers.c:681]: *get_dlg_timeout(): invalid AVP value, using default timeout*" Can someone share a working example? * When i tried hardcoding the timeout value by setting the timeout_avp to a specific value, Kamailio did sense a timeout and hence sent a BYE towards the caller and the Callee side both(which is what the requirement is), however, i do see the *dialog is still not cleared* in the "kamcmd dispatcher.list". Output excerpt below for reference: [root@CPaaSVM ~]# kamcmd dispatcher.list { NRSETS: 1 RECORDS: { SET: { ID: 1 TARGETS: { DEST: { URI: sip:172.27.44.121:5080 ;transport=tcp FLAGS: AP PRIORITY: 0 ATTRS: { BODY: duid=sample-cas;maxload=1000 DUID: sample-cas MAXLOAD: 1000 WEIGHT: 0 RWEIGHT: 0 SOCKET: } LATENCY: { AVG: 111.304000 STD: 1042.193000 EST: 2.385000 MAX: 9999 TIMEOUT: 1 } RUNTIME: { DLGLOAD: *1* } } } } } } It is noteworthy that in case the BYE is initiated by either the caller or the callee, the dialog is cleared properly and the DLGLOAD is set to 0 on call termination. Any pointers for the above questions would be highly appreciated.

Transaction Matching Failed - ACK BYE
by egemen ulus 29 Mar '20

29 Mar '20

Hi All, I'm trying to establish a topology with Kamailio which is located between Asterisk and Outside. My issue is "transaction matching failed" (t_check_trans failed). That means Kamailio does not recognise ACK & BYE message to forwards. I had a check on email list and google but found nothing. I'm using it with record_route. SIP signalling and part of kamailio.cfg is below. Is there any suggestion? route[WITHINDLG] { if (!has_totag()) return; if (loose_route()) { route(DLGURI); if (is_method("BYE")) { setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } else if ( is_method("ACK") ) { xlog("ack is came: $si:$sp\n"); route(NATMANAGE); } else if ( is_method("NOTIFY") ) { record_route(); } route(RELAY); exit; } if (is_method("SUBSCRIBE") && uri == myself) { route(PRESENCE); exit; } if ( is_method("ACK") ) { if ( t_check_trans() ) { route(RELAY); exit; } else { exit; } } sl_send_reply("404","Not here"); exit; } route[NATMANAGE] { #!ifdef WITH_NAT if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } route(RTPPROXY); if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; if (is_request()) { if (!has_totag()) { if(t_is_branch_route()) { add_rr_param(";nat=yes"); } } } if (is_reply()) { if(isbflagset(FLB_NATB)) { if(is_first_hop()) set_contact_alias(); } } #!endif return; } Asterisk > Kamailio INVITE sip:user@outside_ip SIP/2.0 Via: SIP/2.0/UDP asterisk_ip:5060;branch=z9hG4bK1b56cce0 Max-Forwards: 70 From: "KUYRUK" <sip:0553847<tel:+10553847>aaaa@asterisk_ip>;tag=as3dde7cdb To: <sip:user@outside_ip> Contact: <sip:0553847<tel:+10553847>aaaa@asterisk_ip:5060> Call-ID: 62a480bf71d2a1aa0ec94b454cd98945@asterisk_ip:5060 CSeq: 102 INVITE User-Agent: Asterisk PBX 1.8.32.3 Kamailio > Outside INVITE sip:user@outside_ip SIP/2.0 Record-Route: <sip:kamailio_ip;lr;nat=yes> Via: SIP/2.0/UDP kamailio_ip;branch=z9hG4bK7b3f.8e4716eeea4b0dc45cc51d21b5aded57.0 Via: SIP/2.0/UDP asterisk_ip:5060;rport=5060;branch=z9hG4bK1b56cce0 From: "KUYRUK" <sip:0553847<tel:+10553847>aaaa@asterisk_ip>;tag=as3dde7cdb To: <sip:user@outside_ip> Contact: <sip:0553847<tel:+10553847>aaaa@asterisk_ip:5060;alias=asterisk_ip~5060~1> Call-ID: 62a480bf71d2a1aa0ec94b454cd98945@asterisk_ip:5060 CSeq: 102 INVITE User-Agent: Asterisk PBX 1.8.32.3 Outside > Kamailio SIP/2.0 200 OK Via: SIP/2.0/UDP kamailio_ip;branch=z9hG4bK7b3f.8e4716eeea4b0dc45cc51d21b5aded57.0 Via: SIP/2.0/UDP asterisk_ip:5060;rport=5060;branch=z9hG4bK1b56cce0 From: "KUYRUK" <sip:0553847<tel:+10553847>aaaa@asterisk_ip>;tag=as3dde7cdb To: <sip:user@outside_ip>;tag=kv8iml6ur9 Call-ID: 62a480bf71d2a1aa0ec94b454cd98945@asterisk_ip:5060 CSeq: 102 INVITE Record-Route: <sip:kamailio_ip;lr;nat=yes> Contact: <sip:user@outside_ip:5060;alias=x.x.x.x~18005~6;transport=udp> Kamailio > Asterisk SIP/2.0 200 OK Via: SIP/2.0/UDP asterisk_ip:5060;rport=5060;branch=z9hG4bK1b56cce0 From: "KUYRUK" <sip:0553847<tel:+10553847>aaaa@asterisk_ip>;tag=as3dde7cdb To: <sip:user@outside_ip>;tag=kv8iml6ur9 Call-ID: 62a480bf71d2a1aa0ec94b454cd98945@asterisk_ip:5060 CSeq: 102 INVITE Record-Route: <sip:kamailio_ip;lr;nat=yes> Contact: <sip:user@outside_ip:5060;alias=x.x.x.x~18005~6;transport=udp> Asterisk > Kamailio THIS ACK IS NOT ROUTED TO OUTSIDE BY KAMAILIO!!

Kamailiio TLS and Let'sEncrypt certs
by Igor Olhovskiy 29 Mar '20

29 Mar '20

Hi! Actually I’m trying to get Kamailio to work as MS Teams SBC following by perfect article https://skalatan.de/en/blog/kamailio-sbc-teams <https://skalatan.de/en/blog/kamailio-sbc-teams> It works well, but one thing is bothering me. I’m using Let’sEncrypt certs (actually, works well), but with setting in tls.conf verify_certificate = yes require_certificate = yes It’s giving an errors like /usr/sbin/kamailio[4551]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS write:error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed /usr/sbin/kamailio[4551]: ERROR: <core> [core/tcp_read.c:1505]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7f03e6d23d88 r: 0x7f03e6d23e08 (-1) They are resolved with setting these settings (verify/require) to off (actually, as mentioned here - https://www.fredposner.com/1836/kamailio-tls-and-letsencrypt/ <https://www.fredposner.com/1836/kamailio-tls-and-letsencrypt/>), but I’m really curious - why? As I got, it’s using openssl verify on a background, but this check locally passed with openssl verify -CAfile issuer.crt myserver.crt myserver.crt: OK So, is there any tricks to lets encrypt or just some misconfig in tls.cfg? Now it looks like one from article [server:default] method = TLSv1.2+ verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/tls/myserver.key certificate = /etc/kamailio/tls/myserver.crt ca_list = /etc/kamailio/tls/issuer.crt [client:default] method = TLSv1.2+ verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/tls/myserver.key certificate = /etc/kamailio/tls/myserver.crt ca_list = /etc/kamailio/tls/issuer.crt — Regards, Igor

Kamailio OPTIONS Round-Trip
by Soltanici Ilie 27 Mar '20

27 Mar '20

Hi, With Asterisk, we are able to get some peer round-trip connection statistic by setting qualify=yes for the specified peer. It sends periodic OPTIONS to the peer and calculates the time round trip time. It's something like - "Status: OK (30 ms)". Is there any way to achieve this in Kamailio by using nathelper module, or any other? Thank you.
