kamailio fail to start when there are many records in DB in location or in pua table
by laura testi 06 Dec '11

06 Dec '11

Hi all, when there many records in DB tables like location(usrloc use write back mode), pua etc, kamailio fail to start by complaining "no pkg memory left" when try to load (restore) all records from DB to hashtable of location/pua. The share momory are allocated enough for the hashtable, but the default compilation of the PKG_MEMORY_SIZE is 4MB, which allow only restore several thousands records. I know I can increase the PKG_MEMORY_SIZE, but anyway there is a limitation which may fail to restore all records from DB during the startup of kamailio if it reach the limit of the number of records in DB. Is there anyway to reload the hashtable from table by doing query n rows a time and loop until non more result from DB? this will avoid the kamailio startup problem when there are many records in hashtable which are save also in DB. Thank you very much in advanced! Laura

dialog table entry not deleted after call if in-dialog requests are challenged
by Yufei Tao 06 Dec '11

06 Dec '11

Hi I am using dialog module in Kamailio 3.1.5, and find that the dialog table entry does not get deleted after call if in-dialog requests (e.g. session timer refresh re-INVITEs in my case) are challenged. The entry will stay there and get deleted after a long time (some time out? I didn't set any dialog timeouts myself). If I remove the challenge for in-dialog requests, then the dialog entry is deleted right after the call. I use the example config script with a bit of modification for my in-dialog route: route[WITHINDLG] { xlog("L_DBG","WITHINDLG: method=$rm, callid=$ci, cseq=$cs\n"); if (has_totag() ) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { # Filter out bad/faked up in-dialog requests. if ( !is_known_dlg() ) { xlog("L_WARN","WITHINDLG: NOT known dlg!! method=$rm, callid=$ci, cseq=$cs, $fu->$tu\n"); exit; } if (is_method("BYE")) { xlog("L_DBG","WITHINDLG: BYE found within Dialog \n"); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } ########################################################## # challenge: if not CANCEL/ACK else if ( !is_method("CANCEL") && !is_method("ACK") ) { route(AUTH); } ########################################################## xlog("L_DBG","WITHINDLG: Entering RELAY route from WITHINDLG route. \n"); route(RELAY); } else { if (is_method("SUBSCRIBE") && uri == myself) { # in-dialog subscribe requests route(PRESENCE); exit; } if ( is_method("ACK") ) { xlog("L_DBG","WITHINDLG: ACK callid=$ci, cseq=$cs\n"); if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server xlog("L_DBG","ACK being relayed\n"); t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard xlog("L_DBG","ACK without matching transaction-ignore and discard\n"); exit; } } sl_send_reply("404","Not here"); } exit; } } The part that calls route(AUTH) that I added was the cause for the dialog entry not being deleted after call. Here are my dialog related settings: modparam("dialog", "enable_stats", 1) modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_url", DBURL) modparam("dialog", "db_update_period", 20) # use short one to catch short dlgs (default:60) modparam("dialog", "db_mode", 1) # don't use did, so to cope with clients that don't preserve parameters # and mode 1 (fallback to 3261 matching) didn't work?? modparam("dialog", "dlg_match_mode", 2) modparam("dialog", "profiles_no_value", "inbound ; outbound") modparam("dialog", "dlg_extra_hdrs", "Hint: dialog expired\r\n") # default timeout set to max int 0x07FFFF FFFF modparam("dialog", "default_timeout", 2147483647) And I set the dialog flag (4) when receiving the initial INVITE. Any idea why? Am I using the dialog module correctly? Thanks very much!

Issue while initiating database of my new module in kamailio
by Jagdeep S 06 Dec '11

06 Dec '11

Hi All, I am trying to create a new module under the kamailio source base, as part of understanding the framework. But when i start the Kamailio, i am seeing a core dump occuring when my new module is getting initiated and when the database is getting initialised. PFA the files attached containing the config file and source files used for creating module files. I am using the "DEFAULT_DB_URL" as database uri. The core dump backtrace shows that the module init fails at the following point: (gdb) bt #0 0x00000000 in ?? () #1 0x00ef390d in child_init (rank=9172352) at my_mod.c:239 #2 0x081226be in init_mod (m=0xb7515a04) at sr_module.c:922 #3 0x08122630 in init_mod (m=0xb7515c78) at sr_module.c:919 The line 239 in my module file points to the child-init function which initializes the database connectivity ==> "mymod_dbh = mymod_dbf.init(&db_url);" I have written the module using the template provided under the kamailio website. All the parameters are defined properly. Have no idea as to what is going wrong. I tried debugging the core dump using gdb but of no much help. I am not able to run the gdb during runti sr-users(a)lists.sip-router.orgme due to which i am not able to add break points and check. Not sure what the problem is. That's why i generated core dump file and analysed the backtrace, but i can't add break points and run it again as the executable is not involved. Can anyone please let me know what is the issue is or any pointers if i have missed some part of the code due to which the connectivity to db is not happening. Due to this i am not able to proceed further with the testing of my new module. Also any tips on how to do get the gdb debugging during runtime will also be very helpful. Any help is appreciated :). -- Jagdeep S

Hi, I am an absolute beginniner learning SIP and Kamailio to setup Kamailio as the Internet proxy for our Asterisk PBX. My question is how to list the contents of the myself variable from the command line? My Kamailio server displays a list of Aliases on startup. Are these the contents of the myself variable? Thanks Ben

Video questions
by Lucas Alvarez 05 Dec '11

05 Dec '11

Hi, I have integrated Kamailio with asterisk, is it possible to handle video with kamailio and audio with asterisk? I'm using kamailio 3.2, I could difference a video call using sdpopts module, so before the invite is routed to asterisk kamailio sends it to the phone. But I would like that the video media would be peer to peer and the audio follows the path through asterisk. Thanks in advance, Lucas Alvarez

hi, recently i've implemented the module antiflood into kamailio (3.1.5 from GIT) ,the module works and i can see the ip banned with kamctl fifo sht_dump ipban now, when i try to allocate a trusted ip address with permissions module #!ifdef WITH_IPAUTH modparam("permissions", "db_url", DBURL) modparam("permissions", "db_mode", 1) modparam("permissions", "trusted_table", "trusted") #!endif -------------- if(src_ip!=TRUSTEDIP) then i make a sipsak flood test from ip address 1.2.3.4 , but the ip address entered before into trusted table (1.2.3.4 ) again is banned with antiflood module syslog file : INFO: auth [auth_mod.c:312]: auth: qop set, but nonce-count (nc_enabled) support disabled : INFO: permissions [parse_config.c:251]: file not found: /usr/local/etc/kamailio/permissions.allow : INFO: permissions [permissions.c:606]: default allow file (/usr/local/etc/kamailio/permissions.allow) not found => empty rule set : INFO: permissions [parse_config.c:251]: file not found: /usr/local/etc/kamailio/permissions.deny :INFO : permissions [permissions.c:615]: default deny file (/usr/local/etc/kamailio/permissions.deny) not found => empty rule set must i to create this files (permissions.allow, deny) to this module works? or is enough with empty rule set, according with documentation - there are another options into this module, but i need only enabling the trusted ip address part. regards pablo umanzor

undefined symbol: dprint_crit
by Ämin Baumeler 04 Dec '11

04 Dec '11

Hi everybody I cross compiled kamailio for ARM. However, when I try to start kamailio on the ARM machine, it tells me that there are a lot of undefined symbols. E.g. libkcore.so does not find the symbol dprint_crit. Having a look at libkcore.so: $ nm -C -D lib/kcore/libkcore.so|grep dprint U dprint_crit All deployed .so files do not contain dprint_crit. However I found dprint_crit in an object file, that was used for compilation. Namely in dprint.o: $ nm -C dprint.o |grep print 00000000 B dprint_crit I used following commands to cross compile kamailio: export GCC_ARM_HOME=/opt/arm-2009q1/arm-none-linux-gnueabi/ export TOOL_PREFIX=/opt/arm-2009q1/bin/arm-none-linux-gnueabi export CXX=$TOOL_PREFIX-g++ export AR=$TOOL_PREFIX-ar export RANLIB=$TOOL_PREFIX-ranlib export CC=$TOOL_PREFIX-gcc export LD=$TOOL_PREFIX-ld export ARM_TARGET_LIB=/opt/arm-2009q1/arm-none-linux-gnueabi/libc make proper make cfg FLAVOUR=kamailio PREFIX=/root/kamailio/local include_modules="auth auth_db db_text registrar" ARCH=arm TARGET=arm-none-linux-gnueabi make all && make install Thanks Amin

CANCEL not matching INVITES !
by Sammy Govind 03 Dec '11

Hello list, I'm using Kamailio 3.1.5 in front of asterisk servers. Kamailio handles all the SIP registrations. Calls from SIP phones are forwarded to asterisks and then dialled out to Kamailio. root@SBCserver:~# kamailio -V version: kamailio 3.1.5 (x86_64/linux) 76fff5 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, PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 76fff5 compiled on 08:21:33 Oct 27 2011 with gcc 4.6.1 root@SBCserver:~# Problem: When call is initiated from a softphone and is in ringing phase, CANCEL just don't work. I've done some initial debugging and the following piece of code in main route is failing. # CANCEL processing if (is_method("CANCEL")) { xlog("L_NOTICE","$rm from $fu (IP:$si:$sp) ---CAPTURED IN MAIN---\n"); if (t_check_trans()){ t_relay(); xlog("L_NOTICE","$rm from $fu (IP:$si:$sp) ---CHECK TRANS TRUE---\n"); } xlog("L_NOTICE","$rm from $fu (IP:$si:$sp) ---CHECK TRANS FALSE---\n"); exit; } Also the CANCEL fails the has_totag() condition ! The same Call CANCEL scenario works fine for any client on Public IP ! Hope to get some pointers for the solution. Regards, Sammy.
