Greetings list. This might not be related to Kamailio but I thought someone would be able to give a hand in resolving dependency during the installation of rtpengine on Debian 8 Jessie. It is complaining about below dependencies. root@debian-769mb-miami-01:/usr/src/rtpengine# dpkg-buildpackage dpkg-buildpackage: source package ngcp-rtpengine dpkg-buildpackage: source version 6.3.0.0+0~mr6.3.0.0 dpkg-buildpackage: source distribution unstable dpkg-buildpackage: source changed by Sipwise Jenkins Builder < jenkins(a)sipwise.com> dpkg-buildpackage: host architecture amd64 dpkg-source --before-build rtpengine dpkg-source: info: using options from rtpengine/debian/source/options: --extend-diff-ignore=.gitreview dpkg-checkbuilddeps: *Unmet build dependencies: debhelper (>= 10~) libbcg729-dev* dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting dpkg-buildpackage: warning: (Use -d flag to override.) I tried to install debhelper from deb but complained from dh-autoreconf and that itself complained abount debhelpler. So, no one is being installed. Also, If someone can help me how to resolve dependency for libbcg729-dev too. Any pointer or hint or link to some installation guide would be more than welcome. Br, Aqs.

Kamailio 5.1.2 and Module PDB: pdb_query returns always 0

by Stefan Rüetschli

Hi I have here Kamailio 5.1.2 with PDB Module. I use the documented function from PDB-Module as follows: pdb_query("$rU", "$avp(i:82)"); xlog("L_INFO","PDB result $rU: $avp(i:82)\n"); The problem is, that $avp(i:82) is always 0. If I test the PDB-Server, with "pdbt -r localhost:5574 query <phonenumber>" I get a valid response. I use this already with Kamailio 4.3.6 and there it is working. https://kamailio.org/docs/modules/5.1.x/modules/pdb.html Any ideas? Thanks & regards Stefan

Memory leak in tm with push notifications

by Ivaylo Markov

Hello, I am trying to set up Kamailio as a push notifications proxy, closely following the example in the "Kamailio in a Mobile World" presentation (https://www.slideshare.net/FedericoCabiddu/kamailioinamobileworld-51617342). I am running Debian 9 and Kamailio 5.1.3 from the official Debian repositories. I believe the main modules involved in the issue below are tm, tmx, and tsilo. Every call passing through the proxy leads to a small memory leak in the tm module - there is a large amount of "delayed free" memory cells from tm's internal hash table. At some point the shared memory runs out and Kamailio restarts. Using the "kamcmd corex.shm_summary" command I was able to see that the top users of shared memory are "tm: h_table.c: build_cell" and "core: core/sip_msg_clone.c: sip_msg_shm_clone" with the same allocation count. I experimented with removing different parts of the configuration and noticed that commenting out the "t_continue(...)" call in the "PUSHJOIN" route (see slide #22) prevents the leak from happening. Maybe something in that function is incrementing the reference counter to the hash table cell, but it is not decrementing the counter when done? I tried looking around the source code of the tm and tmx modules, but saw nothing suspicious. I also tried using gdb with a breakpoint in t_continue_helper (tm/t_suspend.c:166) hoping to see what else is accessing the htable cell, but was unable to find anything of use. Has someone encountered anything like this? Can you provide more directions on debuggin this? I can provide some bits of configuration, but an entire test setup would be rather difficult, unfortunately. Thank you for your time, Ivo

JSON RPC Error: LUMP_RPL_BODY already added!

by Asgaroth

Hi All, We are trying to query the json rpc server on our registrar for the contact of an aor, but we are seeing the following error(s) being displayed in the log when we query the location table: ERROR: <core> [core/data_lump_rpl.c:83]: add_lump_rpl2(): LUMP_RPL_BODY already added! ERROR: xhttp [xhttp_mod.c:410]: xhttp_send_reply(): Error while adding reply lump We are getting the aor details back in response from the rpc call, but the error's in the log are a little concerning and I cannot see where we are doing something wrong. As an example, the following curl request returns the correct response, but the above error is displayed in the log, Am I doing something wrong here, I cannot see what the issue is: curl --header 'Content-Type: application/json' --data-binary '{ "jsonrpc": "2.0", "method": "ul.lookup", "params": [ "location", "user(a)example.com" ], "id": 3 }' http://registrar.example.com/rpc A secondary question is, is there an upper limit on the size of the "id" parameter? This kamailio instance is v5.0.6. Any thoughts as to what this error means? Thanks

Combining lookup_branches() and t_(next|load)_contacts()

by Nathan Ward

Hi, About a year ago I posted this, but haven’t had much chance to follow up on it: https://lists.kamailio.org/pipermail/sr-users/2017-March/096337.html I’ve been doing some work on this issue (we worked around it until now), and have reduced the config right down to see where things are going wonky. The scenario I have, is inbound calls (to let’s say “A@domain") which I have aliased to two or more different numbers (let’s say “B@domain” and “C@domain”). Both B and C are registering, but are not always registered. I resolve the aliases with alias_db_lookup() (in my sample below, I use seturi() and append_branch() to avoid any confusion about where things may be going weird), then look them up in the location table with lookup_branches(). I then need to do t_load_contacts() and t_next_contacts(), as in some call scenarios I add a serial fork before or after the main call (pre-call announcements etc.). Then, I call t_relay(). This works great most of the time - however, if for example B is registered, but C is not registered, lookup_branches() notes that B is "Not found in usrloc”, and then t_load_contacts() seems to not realise that this isn’t usable, and it attempts to do a DNS lookup for the domain and so on, which I don’t really want it to be doing. Should lookup_branches() be removing a branch it can’t resolve? I would expect it to behave like that, anyway. Can I configure it to do that, or do I need to manually loop through them or something to make sure they resolved, and remove the ones that didn’t? I’ve tried swapping it around, so I call lookup_branches() after t_next_contacts() but the behaviour is the same. I imagine I can’t be the only person trying to do this - how have others made it work? Config sample: seturi('sip:a@domain'); append_branch('sip:b@domain'); xlog("L_DBG", "1 ds: [$ds]\n"); lookup_branches('location'); xlog("L_DBG", "2 ds: [$ds]\n"); t_load_contacts(); xlog("L_DBG", "3 ds: [$ds]\n"); t_next_contacts(); xlog("L_DBG", "4 ds: [$ds]\n"); -- Nathan Ward

Re: [SR-Users] ASN.1 HI2- IRI-Parameters

by Mojtaba

Any idea in this regards? I understood it's structure of HI2Operations as ASN.1 IRI-HI2, I attached it. I think i should convert SIP signalling flow to this structure for transmission. Is it right way that i am doing?

TOPOS module errors

by Enrico Bandiera

Hi, I'm trying to use the TOPOS module to solve some MTU issues we have (we have multiple kamailio servers in our architecture and route/via headers are becoming a problem) The module seems to work but I'm getting these errors on the log: 0(94) ERROR: topos [tps_storage.c:480]: tps_db_insert_dialog(): No database handle - misconfiguration? 0(94) ERROR: topos [tps_storage.c:412]: tps_storage_record(): failed to store I get these errors for some time after running kamailio and then they stop appearing. Data is inserted on topos_d and topos_t on the db, so I'm not sure what the error is referring to. Any idea? Thanks, Enrico.

by Minh Phan

Hi List, I have this warning message in kamailio log when Kamailio handle an OPTIONS message with topos module enabled (I am using Kamailio 5.1.2): WARNING: topos [tps_storage.c:400]: tps_storage_record(): no local address - do record routing for all initial requests In my config file, OPTIONS message is handled this way: if ( is_method("OPTIONS") ) { t_newtran(); record_route(); t_reply("200","OK"); exit; } I have found this issue on Github but it is closed and I am not sure what was the solution: #1483 <https://github.com/kamailio/kamailio/issues/1483> My server receives 4 OPTIONS messages every 10 seconds that give as many warning in my log file. What could I do to get rid of them? Thanks, Minh

Releasing Kamailio v5.1.4

by Daniel-Constantin Mierla

Hello, I am considering to release a new minor version out of branch 5.1, respectively the v5.1.4, sometime next week, likely on Tuesday, June 5, 2018. As usual, if there is any issue not yet reported on github tracker, do it as soon as possible to give it a chance to be fixed. Soon I am going to do the backports of commits with fixes in master that apply in branch 5.1, so keep a close eye and if someone is missing, let me know to push it in the stable branch. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference -- www.kamailioworld.com

Kamailio Behind TCP Load Balancer

by Colin Morelli

Hey all, I'm looking to put Kamailio behind a TCP load balancer that is SIP-unaware. My application is deployed in AWS and I'm tying to place Kamailio behind an ELB. For the most part, everything is fine. For my specific implementation I'm disabling UDP as a signaling transport and using only TLS. This enables me to not have to worry about a SIP-aware LB at the edge because replies to an incoming request will be sent over the existing established TCP socket (avoiding any crazy routing requirements). However - this poses an issue with source addresses. Does Kamailio support anything like the proxy protocol ( http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt) for getting TCP stream information from a load balancer? Do I need to go back to exposing it directly to the world so that I can get source addresses? Thanks, Colin
