TLS certificate verification failed
by Austin Einter 01 Jul '15

01 Jul '15

Hi All I am having a sip client, I am using GNU tls for transport layer security. I am using Kamailio (TLS enabled) to test all the functionalities. I did registration over TLS. It was fine. I tried to make call. I was able to send INVITE. Kamaiio trying to connect to called party (which is again my sip endpoint). That time certificate verification failed. *Error log* * 8(14180) ERROR: tls [tls_server.c:1193]: tls_read_f(): TLS write:error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed 8(14180) ERROR: <core> [tcp_read.c:1326]: tcp_read_req(): ERROR: tcp_read_req: error reading 8(14180) DEBUG: <core> [tcp_read.c:1481]: release_tcpconn(): releasing con 0x7f962f6b6db8, state -2, fd=5, id=3* How do I debug and fix this issue. Can somebody help me out. Thanks Austin

Hello, Is there an API that can notify Kamailio of media inactivity in the RTPProxy? The documentation has something called "timeout_socket" . I don't understand how to use it though. Any help will be greatly appreciated. Thanks Sharath

websocket devices keepalive not working
by Yuriy Gorlichenko 30 Jun '15

30 Jun '15

I try to send keepalive requests (options) to clients at usrloc I tried 4 mechanisms 1) nathelper modparam("nathelper", "sipping_method", "OPTIONS") modparam("nathelper", "natping_interval", 15) modparam("nathelper", "ping_nated_only", 0) modparam("nathelper", "sipping_bflag", 7) modparam("nathelper", "sipping_from", "sip:pinger@mydomain") but it didn't send keepalives to noone client 2)nat_traversal I tried to trigger keepalives with nat_keepalive() when REGISTER coming to my service It works fine with UDP packets modparam("nat_traversal", "keepalive_interval", 15) modparam("nat_traversal", "keepalive_method", "OPTIONS") modparam("nat_traversal", "keepalive_from", "sip:pinger@mydomain") modparam("nat_traversal", "keepalive_state_file", "/var/run/keepalive_state") 3)So I also tried to do it with WebSocket keepalive mechanism, but it still not work for (off course I checked only WS devices) modparam("websocket", "keepalive_mechanism", 15) modparam("websocket", "keepalive_timeout", 15) modparam("websocket", "keepalive_interval", 15) 4) I tried to do it with tcpops Only for ws and tcp (WS is use TCP as i know) tcp_keepalive_enable("15", "5", "15"); same result... So I need mechanism to check all devices for keepalive. I think nathelper works with all protos (As I read at docs) Can somebody explain to me what I doing wrong?

interconnect 2 Kamailio server
by kai.ohnacker＠cbc.de 30 Jun '15

30 Jun '15

Hello, after some trying with SEMS and Blox as SBC, I changed my idea of SIP infrastructure from Kamailio (private) -SBC in DMZ (Private & Public) - www (Public) to Kamailio (private) - Kamailio with rtpproxy in DMZ (Private & Public) - www (Public). Now, my questions are: How can I connect 2 Kamailio SIP server together? Which modules I need? Is there somewhere a good howto? Cheers, Kai Ohnacker

BYE from CANCLEd path gets forwarded to caller
by Daniel Tryba 30 Jun '15

30 Jun '15

I was testing a scenario whith parallel forking (multiple registers) where 2 endpoints answer near simultaniously. When phone that was just a bit slower hangs up, the BYE gets forwarded to the caller and thus the connection is terminated. This is as far as I know for stateful transactions (t_relay()) I always assumed in this scenario the state machine in kamailio would prevent this kind of behavior by itself. Is there a way to prevent these messages being forwarded?
