Regex question
by Oliver Roth 04 Nov '13

04 Nov '13

Hi all Maybe a very simple question - but I cannot see the solution - I am more or less newbie ;) I need to do some string operations in kamailio.cfg. How can I get the cli from the following string: sip:+41523940347@195.216.67.103;user=phone I only would need +41523940347 in a variable Something like $avp(s:myCli) = ^sip:\+(\d{11})@.{1,40}$ Any idea? Thanks in advance Oli

Re: [SR-Users] Capturing-200 Okey(with SDP) from cfg (Daniel Grotti)
by Surendra 04 Nov '13

Hi Daniel, Issue got solved. I am just sharing it. My requirement is I have to parse the SDP from cfg which is coming in 200 OKEY(Initiated by UAC once the called party answers the call). On reply route we can capture the responses for those requests which we set t_on_reply();(externally we have to call for each request). But reply route we can capture all replies. So that we can parse our required headers or msg body. Regards Surendra ******************************

Hi! I have question concerning TLS module. I would like to enable TLS 1.2 protocol. As I understand the TLS module is compiled with openssl, which as far as i know has TLS 1.2 support since openssl 1.0.1. I am wondering if there is way to enable TLS 1.2 on the TLS module? Many thanks Marc

Incoming call problem
by Jason Sia 02 Nov '13

02 Nov '13

Hi, I have kamailio server and a freeswitch server during a call the kamailio passes the call to freeswitch to play a media and back to kamailio for routing to the destination, this works fine however for samsung devices (any ROM using linphone). On other device brands, it does not work it always returns USER_BUSY or NUMBER_NOT_FOUND. After investigation, I found out that if the transport is UDP then it works on all phones, the problem happens if I use TCP as the transport. Anyone had experienced on this? Thanks, Jason

Re: [SR-Users] xHttp_PI Module

Please post your questions to the mailing list instead of sending private e-mails. The subscriber provisioning via xhttp is supported only for plaintext passwords. Set modparam("auth_db", "calculate_ha1", 1) and it will work fine.

Kamailio - RTPProxy - Asymmetric RTP
by Lucas Girard 01 Nov '13

01 Nov '13

Hi all, I have an issue with a Kamailio and rtpProxy, when Asymmetric RTP is used. I have the system running, lines registered in Kamailio are able to call to several destinations, but I have a problem with one provider that use Asymmetric RTP (others providers use Symmetric RTP and I dont have any issues). A -----> Kamailio & RTPProxy ----------> Trunk -------> Provider (Asymmetric RTP) -------> B A is calling B. The problem is that line in kamailio A can listen to B, but B can not listen what A says. I have captured the sip dialog and rtp traffic and I can see that: Kamailio tells to provider that is using the port 52388 (media port in SDP). Providers tells Kamailio that is using the port 5394 (media port in SDP). RTP traffic from Providers to kamailio goes from port 5392 to 52388. RTP traffic from Kamailio to Provider goes from port 52388 to 5392. I have not found an RFC regarding Asymmetric RTP. The question are, why RTP is sent from Kamailio (rtpproxy) to Provider to destination port 5392? It should use 5394 as SDP indicate? or, port 5392 is learned when RTP traffic was received from 5392 to 52388? # kamailio -V version: kamailio 3.3.0 (i386/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, F_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 22:17:07 Jun 18 2012 with gcc 4.4.5 # rtpproxy -v 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 I hope to be clear with this explanation.

msilo - use case: registered but not reachable
by Marc M. 01 Nov '13

01 Nov '13

Hi! I have a simple msilo setup which is working fine: -If the user is registered, the messages are delivered right away -If the user is not registered, the messages are stored in msilo and got deliverd at the next register Here is the relevant part of the cfg: --------------- if (is_method("MESSAGE")) { log(1,"-------------------------------------------------------->WE HAVE A NEW MESSAGE\n"); route(MSILO_MESSAGE); } . . . route[MSILO_MESSAGE]{ if (lookup("location")){ t_relay(); }else{ m_store("$ru"); sl_send_reply("200", "OK"); } exit; } . . . route[REGISTRAR] { if (is_method("REGISTER")) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); # uncomment next line to do SIP NAT pinging setbflag(FLB_NATSIPPING); } if (!save("location")) sl_reply_error(); # MSILO - dumping user's offline messages m_dump(); exit; } } ------------------- Thats working fine. Now, we have a use case where a user is registered, but got terminated in between abd not reachable. So the user is in the userloc table, but not reachable. In this case ,since the user is still in userloc, the t_relay() will be executed, and it drops a 408 (timeout) code which is fine. However, the process end here. The message is then dropped. What i would like to achieve is to make sure that t_relay() was executed with 200, otherwise store the message and deliver it at the next register. I was trying this: ------------ ##storing offline messages (new) route[MSILO_MESSAGE]{ if (lookup("location")){ if (!t_relay()) { m_store("$ru"); sl_send_reply("200", "OK"); } exit; } else{ m_store("$ru"); sl_send_reply("200", "OK"); } exit; } -------- but i have still the same behaviour. Can you help me, what do I wrong? Many thnaks Marc. M

Hi, what do you mean with "capture from cfg file" ? Do you want to log 200OK message in kamailio log file ?
