Create dialog for SIP PRESENCE

Hi, i'm trying to create SIP dialog for SUBSCRIBE messages, but it's still unsuccessful (. if (is_method("SUBSCRIBE")) { setflag(4); dlg_manage(); xlog("L_INFO", "DLG_count=$DLG_count, DLG_status=$DLG_status, DLG_lifetime=$DLG_lifetime - (Method=$rm RURI=$ru From=$fu To=$tu IP=$si DST=$du -- $ci)\n"); } In kamailio.log: May 10 18:15:11 /usr/sbin/kamailio[18355]: DEBUG: dialog [dlg_hash.c:652]: no dialog callid='265619152(a)192.168.4.18' found May 10 18:15:11 /usr/sbin/kamailio[18355]: DEBUG: dialog [dlg_hash.c:683]: no dialog callid='265619152(a)192.168.4.18' found May 10 18:15:11 /usr/sbin/kamailio[18355]: DEBUG: dialog [dlg_handlers.c:1170]: Callid '265619152(a)192.168.4.18' not found Does kamailio 3.3.4 support Dialog for PRESENCE (Subscribe, Publish, Notify) ?

Issue in Multi Domain Environment
by aawaise 14 May '14

14 May '14

I have deployed two kamailio servers with independent domain names, BOTH sharing the same database. When an "INVITE" packet approaches one server from a user. As per my understanding it checks "Location Table" (containing online users) to find about status (online or not) of called user. If user is present in LOCATION TABLE, kamailio server sends INVITE to callee else it disconnects the call. In LOCATION TABLE, DOMAIN NAME is also mentioned along with user name, I want to extract that domain name of callee user from LOCATION TABLE with every INVITE packet. What variable stores this information ?? How can it be extracted ?? I have tried using "$du". It consumes RURI and gives domain name, it picks domain name from invite packet, which is not required here. Requirement is to pick domain name from LOCATION TABLE, by which user is logged into the system. (In multidomain setup, they both can be different). I have also tried "$td", they also pick domain name from INVITE packet header. I want to print (i.e xlog) value of domain from the LOCATION TABLE. And it is bothering for quite a few days now. Any help will be much appreciated. Thanks. Regards, Aawaise. -- View this message in context: http://sip-router.1086192.n5.nabble.com/Issue-in-Multi-Domain-Environment-t… Sent from the Users mailing list archive at Nabble.com.

SHM error after few days...
by Krishna Kurapati 13 May '14

13 May '14

Hi, After few days of running kamailio (I am using TLS for client), suddenly I see that the connections are being dropped. When I restart kamailio, I see following errors: Stopping kamailio: [FAILED] Not starting : invalid configuration file! 0(20563) : <core> [mem/shm_mem.c:168]: shm_getmem(): ERROR: shm_mem_init: could not attach shared memory segment: Cannot allocate memory 0(20563) : <core> [mem/mem.c:125]: init_shm_mallocs(): could not initialize shared memory pool, exiting...

It started fine initially. However, after I noticed connection drops, I see the above issue. THen I reduced shared memory to 2048M and it started fine. I am under the impression that shared memory is just a filed I/O mapped which can be several hundred gigs. I looked at my filesystem. It looks fine df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 958788080 200734800 709349640 23% / tmpfs 3975996 0 3975996 0% /dev/shm /dev/sda1 495844 37498 432746 8% /boot What could be wrong here? Any help greatly appreciated. Krish Kurapati

RTP ports
by Neville D'Souza 13 May '14

13 May '14

HI , How do I find out which udp ports my kamailio server is using. In Kamailio.cfg I am using socket like below. #!ifdef WITH_NAT # ----- rtpproxy params ----- #modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") I need to know the exact port range to open ports on my firewall if necessary. Our Kamailio server works just fine outside our network, but when I try to make calls through linphone client using a android device inside our network, as soon as I pick up the call it gets disconnected. The same thing happens when someone from outside tries to call in to our network. Funny part is when I use a desktop client like jitsi the calls between 2 users in the network or with someone outside the network work fine. I am guessing the rtp traffic is being dropped by the firewall when using linphone android client. It was working fine previously but after a firewall OS update it stopped working.

Why Kamailio reply with null compression method when TLS handshake?
by 刘日新 13 May '14

13 May '14

Hi, all. I has set up a Kamailio server with TLS & compression enabled, I thought I set most things suitable , I has set modparam("tls","tls_disable_compression",0) I can find such log records as below when Kamailio boost: 0(10905) INFO: tls [tls_init.c:549]: init_tls_h(): tls: _init_tls_h: compiled with openssl version "OpenSSL 1.0.0-fips 29 Mar 2010" (0x10000003), kerberos support: on, compression: on 0(10905) INFO: tls [tls_init.c:557]: init_tls_h(): tls: init_tls_h: installed openssl library version "OpenSSL 1.0.0-fips 29 Mar 2010" (0x10000003), kerberos support: on, zlib compression: on compiler: gcc -fPIC -DOPENSSL_PIC -DZLIB -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DKRB5_MIT -m64 -DL_ENDIAN -DTERMIO -Wall -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -Wa,--noexecstack -DMD32_REG_T=int -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DAES_ASM -DWHIRLPOOL_ASM 0(10905) WARNING: tls [tls_init.c:611]: init_tls_h(): tls: openssl bug #1491 (crash/mem leaks on low memory) workaround enabled (on low memory tls operations will fail preemptively) with free memory thresholds 11534336 and 5767168 bytes 0(10905) INFO: <core> [cfg/cfg_ctx.c:613]: cfg_set_now(): INFO: cfg_set_now(): tls.low_mem_threshold1 has been changed to 11534336 0(10905) INFO: <core> [cfg/cfg_ctx.c:613]: cfg_set_now(): INFO: cfg_set_now(): tls.low_mem_threshold2 has been changed to 5767168 And I run kamcmd tls.options, I got: { force_run: 0 method: TLSv1 verify_certificate: 0 verify_depth: 9 require_certificate: 0 private_key: /ca/cert.pem ca_list: certificate: /ca/cert.pem cipher_list: session_cache: 1 session_id: vic22 config: /etc/kamailio/tls.cfg log: 3 debug: 3 connection_timeout: 600 disable_compression: 0 ssl_release_buffers: -1 ssl_freelist_max: -1 ssl_max_send_fragment: -1 ssl_read_ahead: 0 send_close_notify: 0 low_mem_threshold1: 11534336 low_mem_threshold2: 5767168 ct_wq_max: 10485760 con_ct_wq_max: 65536 ct_wq_blk_size: 4096 } But when My UA connect to this server, when TLS handshake, I can find that the clienthello with two compression method :1 (deflate) and 0 (null), but the server side reply with just one compression method: 0( null), thus the compression was disabled through the following communication. Why? are there any others issue can impact the behavior of Kamailio? Any hints will be appreciated. B.R. Rixin liu

Children, PKG_MEM and IMS
by Andrea Meroni 13 May '14

13 May '14

Hi all, i'm a little bit confused about the #children/PKG_MEM mechanism: in my setup (a simple IMS core with one P-CSCF, one I-CSCF, one dispatcher and 2 S-CSCFs) i wish to manage the highest possible #calls, but i don't know which is the ideal setup. I mean, i'm running all this components in VMs (with mem = 2048MB and smp = 8) inside a desktop machine with RAM = 32 GB and 8 processors; is it worth to define #children = #processors and setting an high value of PKG_MEM (for example 128MB) or use an higher #children (for example 64) with less PKG_MEM (for example 16MB)? Someone could explain me better how the mechanism works? Thank you, Andrea

Version support
by Jan Gaida 12 May '14

Hello, Which versions of Kamailio (OpenSER) are officially supported (e.g. actively patched) ? Is there a list of EOL dates for all versions or what is the general rule?

Problem with rtpproxy and rtpproxy_manage()
by aft 12 May '14

12 May '14

Hi, I'm using kamailio from latest git-HEAD. The rtpproxy i'm using also from latest git. Our network topology is following : sip-softphone--------->kamailio/rtpproxy-------->softswitch---->gateway Because of saving bandwidth we need to use the "re-packetization" feature of rtpproxy. When we don't use it, it works perfectly without any glitches. Now if we use the repacketization feature like following : if (is_request()) { rtpproxy_manage("co"); } if (is_reply()) { rtpproxy_manage("z80"); } Then a bizzare thing happens. Suddenly rtp packets from gateway stops coming. So we don't have any voice in softphone, although everything seems ok at the "mobile phone's end." This is bizzare at multiple levels, as you can see we are using repacketize feature to increase the payload size from "proxy to softphone" leg. So we actually don't touch the packets from "softphone to proxy" leg. So how the gateway predicts this and decides not to send packets is beyond my understanding. As far as i can understand, rtpproxy_manage() is doing something to SDP which makes it impossible to send packets through the proxy. I will provide further information if anybody wants to look at it. Thanks in advance. -- -Cheers -Arif
