Issue when SRTP enabled in the SIP clients
by Jonathan Martin 21 Dec '11

21 Dec '11

Hi, I followed this web article to install Kamailio 3.2 and RTPProxy on Debian Squeeze x64: http://kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour The system is running on a public IP address outside of our corporate LAN. I have been testing it using pjsua v2 alpha 2 from the pjsip.org project. I am having an issue when I enable srtp in the pjsua clients. If both pjsua clients are running on machines on our corporate LAN (symmetric NAT), the call succeeds and I get audio and video. If one of the clients is running outside of the corporate LAN, the call connects but I do not get any audio or video. If I turn off srtp in both clients and try the call again, audio and video starts working. Is there any additional configuration I need to make in the kamailio.cfg file when I intend to use srtp in the clients? RTPProxy info: Basic version: 20040107 Extension 20050322: Support for multiple RTP streams and MOH Extension 20060704: Support for extra parameter in the V command Extension 20071116: Support for RTP re-packetization Extension 20071218: Support for forking (copying) RTP stream Extension 20080403: Support for RTP statistics querying Extension 20081102: Support for setting codecs in the update/lookup command Extension 20081224: Support for session timeout notifications Kamailio info: version: kamailio 3.2.0 (x86_64/linux) flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, 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 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 10:23:25 Nov 2 2011 with gcc 4.4.5 Regards, --Jonathan

回复： Why? there isn't a syslog.conf under mykamailiodirectory?
by sunny_day 21 Dec '11

21 Dec '11

Elena, your advice is very useful for me. Thank you very much. :-) However,i think i should introduce the environment I now used. First, there are 3 users on the linux, and one kamailio.cfg for each user. I am not the root user. So i don't have the priviledge to write the diretory---->/var/log/messages According the introduction you provided for me, I want to setup my own log file. But I am not sure whether it will work. The idea is: 1. In kamailio.cfg set "log_facility=LOG_LOCAL5" 2. In syslog.conf set # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none;local5.none /var/log/messages 3. In syslog.conf set # log messages with LOG_LOCAL5 in /var/log/kamailio.log local5.* -/home/albert/mylocal/myvar/log/kamailio.log Any idea will be appreciated.

Database connections
by Mariana Arduini 20 Dec '11

20 Dec '11

Hello all, I'm running some performance tests and need to know how does the database connections work. Are they open when we start OpenSER and are kept open for each process or they just open before a query and closed afterwards? Does anyone know where I can find such info? Thanks in advance!

Dispatcher module with call load balancing
by Mino Haluz 20 Dec '11

20 Dec '11

Hi, I would like to use the dispatcher module with algorithm 10 - call load balancing. But there are multiple things that are a bit unclear to me. I have multiple gateways that can serve different maximum number of calls. 1) Can I somehow set the maximum calls count for each dispatcher gateway, so that it can fairly distribute the calls? I know it is stateless module, but how could I solve this? 2) Is there any method how can I get the current number of calls for each gateway from the dispatcher module? 3) What is the expiration timer in the dispatcher module for dialogs if the dialog is canceled uncleanly ? 4) Imagine I will restart kamailio, it will lose the call count and the distribution will be incorrect. Maybe it could nice, that kamailio would offer MI command to set these values. Thanks for the responses, Mino

Olle , Thank you very much for your reply! I am not the root user on the unix system. but I want to customize the log file for the function: xlog. Now, I don't know where to see the content what xlog writes. It can help me to debug the script of kamailio.cfg i edited. what i do is collect the CDRs by dialog and acc modules. Any suggestion will be appreciated. Thanks a lot ! ------------------ albert.gu ------------------ Original ------------------ From: "Olle E.

force_send_socket and IPv6
by Andreas Granig 19 Dec '11

19 Dec '11

Hi, Is it possible to use force_send_socket() with an IPv6 address in Kamailio 3.1? I get the error ERROR: fix_actions: force_send_socket: could not resolve X:X:X:X:X:X:X:X:5060 where X:X:X:X:X:X:X:X is my IPv6 address. Another problem (not sure if it's a real problem but looks weird) is when I use X::X:X:X:X:X which is actually X:0:0:X:X:X:X:X, then when starting kamailio, the "Listening on" message on stdout expands it correctly, but the error message for force_send_socket drops a 0, so it says that it can't resolve 'X:0:X:X:X:X:X' which is not a valid IPv6 address, right?

rtpproxy and IP6 in c= line
by Andreas Granig 19 Dec '11

19 Dec '11

Hi, Is there a flag in the rtpproxy module to force a change of the IP protocol field? When a call comes from an IPv4 endpoint and you do the bridging to IPv6, then the c= and o= lines contain the IPv6 address, but the address family is still IP4 (e.g. "c=IN IP4 10.10.8.22" becomes "c=IN IP4 fe80::1"). In case of bridging from IPv6 to IPv4, the field is correctly set to IP4 though (e.g. "c=IN IP6 fe80::1" becomes "c=IN IP4 10.10.8.22"). Is there something special to be taken into consideration? I couldn't find any hints in the rtpproxy module that it tries or would try to set that correctly (kam-3.1.5). Andreas
