Again problems with ACK and Bye
by Stoyan Mihaylov 16 Mar '12

16 Mar '12

In wireshark, there are 2 fields - Source and Destination. I am curious if there are variables in Kamailio which can show me those values. System: MYIP - IP of kamailio sip.mydomain.com - address of kamailio User (Imsdroid for Android) ->Kamailio->Asterisk->Kamailio (same) ->Other user. Problem - register, voice, video, and ring are OK, but ACK and BYE are going in dead loop - and this happens may be around in 50% of cases - not in all cases. If I am using other client (like … [View More]hardware SIP phones), then I have no problems, but it is really hard to find some client for Android which supports video with Kamailio. To solve problem, I made one function in Kamailio.cfg - ACKBYE, which is called only within dialog. And within dialog is called in main route. route[ACKBYE] { #!ifdef WITH_MYFORWARD xlog("SCRIPT: AckBye $td;$si;$du;$dd\n"); if((($td=="sip.mydomain.com")||($td=="MYIP"))&&($si=="MYIP")){ $du=$sht(forw=>$ft); xlog("SCRIPT: AckBye2 $td;$si;$du\n"); return; } #!endif return; } Of cource I have if(is_method("INVITE")){ ds_select_dst("1","4"); $sht(forw=>$ft)=$du; } This worked for long time. But then we updated client (libraries etc), and problem appeared again - from time to time. Calls between 2 same clients can pass 2 or 5 times, and then problem appear. Before - $td and $si showed destination and source but now there is difference: ERROR: <script>: SCRIPT: AckBye 192.168.2.251;MYIP;<null>;<null> $td in this case show destination, which is correct, but in wireshark, destination and source = MYIP.

define-check for dlg_var doesn't work
by Sven Knoblich 16 Mar '12

16 Mar '12

sip-router:master Hi all, i want to use the define-check also for dlg_var. But after testing a bit it seems to me, that define does not work with dlg_var's. I am always getting a true. Did i miss something? # $dlg_var(test) is not defined if( defined $dlg_var(test)) { xlog("L_Notice","dlg_var $dlg_var(test) is defined\n"); } I hope anybody can help me to clarify this. Thanks in advance, Sven

[nube] Simple TCP/TLS proxy?
by Matthew Roderick 15 Mar '12

15 Mar '12

Hi All, I've been googling for a little while now and although I found others asking the question and answers says "yes it's possible" I haven't managed to find out *how* to do it! I have a relatively simple scenario where I'd like to use Kamailio (or something else?) to take TCP or UDP connections from my Linksys PAP2T ATA and proxy them to my sip provide which only allows TLS connections (obviously the Linksys doesn't support TLS). The kicker is that, although I understand the theory and … [View More]

collecting statistics
by Klaus Darilion 15 Mar '12

15 Mar '12

Hi! I want to collect statistics on a load-balancer, e.g. how many NOTIFYs, SUBSCRIBEs, ... and the respective response codes, e.g. NOTIFYs-200, NOTIFYs-408,...., response time from the backend-servers, ... Further I want to do this separately for each backend-server in the cluster, i.e. for every IP address in the dispatcher list. Built in statistics or not detailed enough, so thought of implementing the counting and measuring in script using htable and a periodic timer which dumps the … [View More]

Kamailio consumes memory
by Martin Tichatschek 15 Mar '12

15 Mar '12

Hi everyone, I have a problem with Kamailio consuming memory. I started testing with Kamailio 3.2.1 upgraded to 3.2.2 and also tested 3.1.5, everywhere the same problem. Whereas Kamailio 1.5.0 is working fine. Kamailio -V shows the following: kamailio@test:~$ kamailio -V version: kamailio 3.2.2 (i386/linux) 98ba92 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, … [View More]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: 98ba92 compiled on 17:51:30 Feb 29 2012 with gcc 4.2.4 kamailio@test:~$ My test scenario consists of two SIPp servers (a UAC and a UAS) and the Kamailio in the middle proxying the SIP traffic. The UAC sends 300 calls per second (INVITE, 100, 180, 200, ACK) and releases the calls (BYE, 200) after 20 sec call duration. UAS is simply sending back the right responds. Protocol is UDP. After some minutes the Kamailio floods the syslog file with error messages indicating that he is running out of memory. The SIPp shows retransmissions and also timeouts. When I stop the test and do a single call I get some lines of error messages. I found three different sets of error messages for a single call so far: Mar 2 09:35:44 test P-CSCFtest[21251]: ERROR:<core> [parser/msg_parser.c:172]: get_hdr_field: out of memory Mar 2 09:35:44 test P-CSCFtest[21251]: INFO:<core> [parser/msg_parser.c:353]: ERROR: bad header field [To:<sip:00498111111] Mar 2 09:35:44 test P-CSCFtest[21251]: ERROR: tm [t_lookup.c:1118]: ERROR: reply cannot be parsed Mar 2 09:35:44 test P-CSCFtest[21251]: ERROR:<core> [msg_translator.c:1884]: ERROR: build_res_buf_from_sip_res: out of mem Mar 2 09:35:44 test P-CSCFtest[21251]: ERROR:<core> [forward.c:794]: ERROR: forward_reply: building failed Mar 2 09:35:44 test P-CSCFtest[21228]: ERROR:<core> [msg_translator.c:1884]: ERROR: build_res_buf_from_sip_res: out of mem Mar 2 09:35:44 test P-CSCFtest[21228]: ERROR: tm [t_reply.c:1786]: ERROR: relay_reply: no mem for outbound reply buffer Mar 2 09:35:44 test P-CSCFtest[21228]: ERROR:<core> [msg_translator.c:2036]: ERROR: build_res_buf_from_sip_req: out of memory ; needs 311 Mar 2 10:19:43 test P-CSCFtest[21346]: ERROR:<core> [msg_translator.c:1884]: ERROR: build_res_buf_from_sip_res: out of mem Mar 2 10:19:43 test P-CSCFtest[21346]: ERROR: tm [t_reply.c:1786]: ERROR: relay_reply: no mem for outbound reply buffer Mar 2 10:19:43 test P-CSCFtest[21346]: ERROR:<core> [msg_translator.c:2036]: ERROR: build_res_buf_from_sip_req: out of memory ; needs 311 Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR:<core> [action.c:852]: ERROR: do_action: memory allocation failure Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR:<core> [action.c:1568]: run action error at: /usr/local/etc/kamailio//kamailio.cfg:28 Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR:<core> [action.c:852]: ERROR: do_action: memory allocation failure Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR:<core> [action.c:1568]: run action error at: /usr/local/etc/kamailio//kamailio.cfg:32 Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR:<core> [parser/parse_from.c:71]: ERROR:parse_from_header: out of pkg_memory Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR: tm [t_lookup.c:1326]: ERROR: new_t: no valid From in INVITE Mar 2 10:20:16 test P-CSCFtest[21328]: ERROR: tm [t_lookup.c:1478]: ERROR: t_newtran: new_t failed Mar 2 10:20:16 test P-CSCFtest[21328]: WARNING:<core> [receive.c:209]: WARNING: receive_msg: error while trying script I repeated the test various times, it always generates a memory problem. The "top" command shows that the free memory is decreasing constantly during the test. Stopping the test and waiting for some time (1 hour) doesn't increase the free memory showed by "top". Only a restart of the Kamailio frees the memory again. I executed the test with 30 calls per second too and got the same behaviour (after some more minutes). I finally simplified the Kamailio config as far as possible and came to this minimum: #!KAMAILIO listen=10.10.10.10:5060 children=30 user="kamailio" group="kamailio" debug=2 disable_core_dump=yes log_facility=LOG_LOCAL0 log_name="P-CSCFtest" server_signature=no sip_warning=0 syn_branch=0 disable_tcp=yes ####### Modules Section ####### mpath="/usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/" loadmodule "tm.so" ####### Main Routing Logic ######## route{ if (src_ip==1.2.3.4) { rewritehost("5.6.7.8"); } else { rewritehost("1.2.3.4"); }; rewriteport("5061"); t_relay(); } This config still generates the memory problem. After replacing the "t_relay()" with the stateless "forward()" the problem is gone. I played around with the number of child processes too, but no difference. Is this a memory leak of the TM module or is there a different explanation? Regards Fred [View Less]

Timer

Hello we installed kamailio succesfully but we have a few problems regarding calls towards special numbers in which an INVITE is not replied with 200 OK but instead with 183 session progress sent at 1 min interval, during which the caller hears a waiting message. unless a human operator answer the call, no 200 OK is replied. if that waiting time is too long, we noticed that the call is hanged up after 3 min, 180s, that is 3 * session progress . 408 timeout is sent to the caller and cancel to … [View More]
