Os on virtual machine

Hi guys, We are using vmware to run kamailio. The thing is that they give us support only if we install Red Hat. Did you test kamailio on RH? Any issues or things to have in mind? What linux dist do you recommend? Thanks! Diego.

Spurious dialog timeouts
by Pranathi Venkatayogi 03 Feb '17

03 Feb '17

Hi, I have two kamailio proxies between the customer and agent. Cust -> proxy1 -> proxy2 -> agent. The dialogs are successfully established and remain undeleted within the customer / agent client. However in Proxy2 I am seeing spurious dialog timeout. I am attaching kamailio log trace below. Also attached is the siptrace on the agent/customer side. Question: How is this dlg_ontimeout() generated despite dialog being successfully established and undelete? How to avoid it. Kamailio (proxy2) log: 7719 Feb 3 21:41:20 labsip00 /usr/sbin/kamailio[11323]: exec: *** cfgtrace:local_route=[dialog:end] c=[//etc/kamailio//routing.cfg] l=490 a=16 n=if 7720 Feb 3 21:41:20 labsip00 /usr/sbin/kamailio[11323]: exec: *** cfgtrace:local_route=[dialog:end] c=[//etc/kamailio//routing.cfg] l=481 a=24 n=is_known_dlg 7721 Feb 3 21:41:20 labsip00 /usr/sbin/kamailio[11323]: exec: *** cfgtrace:local_route=[dialog:end] c=[//etc/kamailio//routing.cfg] l=482 a=63 n=assign 7722 Feb 3 21:41:20 labsip00 /usr/sbin/kamailio[11323]: exec: *** cfgtrace:local_route=[dialog:end] c=[//etc/kamailio//routing.cfg] l=489 a=16 n=if 7723 Feb 3 21:41:20 labsip00 /usr/sbin/kamailio[11323]: exec: *** cfgtrace:local_route=[dialog:end] c=[//etc/kamailio//routing.cfg] l=485 a=26 n=xlog 7724 Feb 3 21:41:20 labsip00 /usr/sbin/kamailio[11323]: INFO: <script>: Translation: Dialog ended for sip:agent2@translation.sms-test.cyracom.com.

Websocket TLS Issue
by Jade SZ 03 Feb '17

03 Feb '17

Hi Guys, I am trying to setup the following flow: Browser >> WSS >> HA Proxy >>> WSS >> Kamailio But getting TLS errors in Kamailio logs: *[29634]: ERROR: <core> [tcp_read.c:1321]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7f68ebe872b0 r: 0x7f68ebe87330* *[29631]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number* Browser <-----wss---->Kamailio works fine with same certs. Both HA Proxy and Kamilio are installed on separate servers, hosting on same port with different domain. Kamailio tls.conf has method = TLSv1 *@HA Proxy:* openssl s_client -connect HA-PROXY-DOMAIN:*10443* SSL-Session: Protocol : TLSv1.2 *@Kamailio :* openssl s_client -connect KAMAILIO-DOMAIN:*10443* SSL-Session: Protocol : TLSv1 So I made HA Proxy to be on TLSv1 "ssl-default-bind-options force-tlsv10" But still I get the same TLS error in Kamailio. *HA Proxy config looks like:* *frontend public* * bind *:10443 ssl crt /etc/haproxy/certs/cert.pem* * acl is_websocket hdr_end(host) -i m1.some-domain.com <http://m1.some-domain.com>* * use_backend wss if is_websocket* * default_backend wss* *backend wss* * timeout server 600s* * server ws1 k1.some-domain.com:10443 <http://k1.some-domain.com:10443>* * server ws1 k2.some-domain.com:10443 <http://k2.some-domain.com:10443>* Need some direction, thanks in advance.

id column i tables
by Kristian F. Høgh 02 Feb '17

02 Feb '17

Hi list, We provision our kamailio database from an external system. In the future we would like to provision from two different systems. To prevent the two systems from touching each others data, we would like to create views from the two tables. provision system 1 would write to table1 provision system 2 would write to table2 kamailio will read a view over the two tables. The tables we will create views over are: - address - aliases - dispatcher - uri - usr_preferences Now to my question :-) Does kamailio use the id field in any of the tables above? The id's are auto-incremented, and we might get conflicts between table1 and table2 *Kristian Høgh* Telefon: 4422 8822 support(a)uni-tel.dk[1] Gydevang 19 | 3450 Allerød www.uni-tel.dk [2] -------- [1] mailto:support@uni-tel.dk [2] http://www.uni-tel.dk

Disabling DNS SRV records checks
by Ahmed Fouad 01 Feb '17

01 Feb '17

Hi, I'm running kamailio version 4.1 and having the following DNS related configuration use_dns_failover = off dns_try_naptr = no dns_udp_pref = -1 dns_try_ipv6 = off dns_retr_time=1 dns_retr_no=1 dns_servers_no=1 dns_use_search_list=no But still am seeing SRV record checks for my domains which I like to completely disable these checks and only use A records only. x.x.x.x.57828 > 8.8.8.8.53: 7417+ SRV? _sip._udp.subdomain.com 8.8.8.8.53 > x.x.x.x.57828: 7417 NXDomain 0/1/0 (129) I can't find a DNS option to disable SRV checks. Can you please advise ?

Hi Guys, Just wanted to clarify the following case: what should be result of sdp_with_transport("RTP/SAVPF") on line: m=audio 10231 UDP/TLS/RTP/SAVPF 111 103 104 9 0 8 106 105 13 126 I am having a weird behavior for two different versions of Kamailio. I hope I am doing something wrong. kamailio 4.3.2 => sdp_with_transport("RTP/SAVPF") = true kamailio 4.4.5 => sdp_with_transport("RTP/SAVPF") = false -- Regards M. Salman VoIP Professional
