Hello, 3 crashes occurred today (we never seen crashes on this server before) during a period of 20 minutes. I had a look to the coredumps. Here is a quick overview of the first entries of "bt full": core.27671 : #0 0x00007f5577048d65 in run_trans_callbacks_internal (cb_lst=0x7f5560abbd50, type=2, trans=0x7f5560abbce0, params=0x7fff3712acb0) at t_hooks.c:286 core.27656 : #0 0x00007f557700a048 in free_cell (dead_cell=0x7f5560abbce0) at h_table.c:175 core.27685 : #0 0x00007f5577048d65 in run_trans_callbacks_internal (cb_lst=0x7f5560abbd50, type=2, trans=0x7f5560abbce0, params=0x7fff3712acb0) at t_hooks.c:286 core.27689 : #0 0x00007f5577048d65 in run_trans_callbacks_internal (cb_lst=0x7f5560abbd50, type=2, trans=0x7f5560abbce0, params=0x7fff3712acb0) at t_hooks.c:286 core.27691 : #0 0x00007f5577048d65 in run_trans_callbacks_internal (cb_lst=0x7f5560abbd50, type=2, trans=0x7f5560abbce0, params=0x7fff3712acb0) at t_hooks.c:286 core.31977 : #0 0x00007f038e66fdee in free_cell (dead_cell=0x7f037811ebe0) at h_table.c:157 core.31994 : #0 0x00007f038e6ab65a in t_forward_nonack (t=0x7f037811ebe0, p_msg=0x7f038fdca438, proxy=0x0, proto=0) at t_fwd.c:1762 core.3700 : #0 0x000000000061697a in fm_insert_free (qm=0x7f19861fa000, frag=0x7f19864d53e8) at mem/f_malloc.c:245 core.3727 : #0 0x00000000006167a4 in fm_extract_free (qm=0x7f19861fa000, frag=0x7f19864f4cc8) at mem/f_malloc.c:208 I don't know how to proceed now.

Re: [SR-Users] Auth module Issue:UA getting challanged thrice when load is high

by Daniel-Constantin Mierla

Hello, are there any error messages in the syslog? Maybe setting debug level for auth modules to 3 and looking at logs will help to reveal what is happening. Be sure syslog is in async mode, otherwise it will slow down processing.

routing based on TLS auth

by Max

Hi. I've got bunch of sip gateways to use and bunch of asterisk instances connecting to my Kamailio over TLS (own CA used). I'd like to match source with destination based on TLS authentication: * all the calls from asterisk A (TLS cert A) allowed via provider A * all the calls from asterisk B (TLS cert B) allowed via provider B ... * all the incoming calls from provider A forwarded to asterisk A (TLS cert A) * all the incoming calls from provider B forwarded to asterisk B (TLS cert B) ... * calls not coming from provider X or via TLS dropped. Providers are regular VoIP gateways (login:password, connection via SIP). I'm pretty sure this is possible with Kamailio but I'd appreciate any examples and pointers to modules I should use to implement this. Or detailed explanation of why this is a bad idea. Also, I'm not sure where it's better to place user database - should it be separate on per-asterisk basis? Central in Kamailio? No user db needed at all? cheers, Max.

Auth module Issue:UA getting challanged thrice when load is high

by Surendra.P

Hello Daniel, I have a concern regarding auth module, I am running 2000 TPS for 1000000 subscribers, using SIPP. What I observed when you run small load like 500 TPS, everything get passed, but for 2000 TPS With same subscriber.csv file some of the subscribers getting challenged. May I this why auth module is behaving like this.. below are the parameters which I configured in auth module modparam("auth", "nonce_expire", 3600), rest all parameters default values. Regards Surendra

Strange TLS problem

by Pete Kelly

Hi I am trying to use the [client] directives in tls.cfg for the first time. For my configuration I need to connect to 2 servers, both via TLS and both using different certs. I have defined an entry in tls.cfg like [client:1.2.3.4:5061] [client:5.6.7.8:5071] and I also have an entry in dispatcher tables for each server using the URI format sip:1.2.3.4:5061;transport=tls With this configuration, I expect dispatcher to send OPTIONS to each server, and Kamailio to resolve the host in dispatcher to the correct client section of tls.cfg and negotiate a connection. However this is not happening. Dispatcher module is trying to send OPTIONS as expected, and it is using TLS as expected but it is not using the correct [client] section from tls.cfg. Instead it is always falling back to [client:default], and if that is not present it then tries to look for some internal Kamailio defaults. Has anyone come across this issue before? Debug logs don't yield anything useful, however my suspicion is that Kamailio may be trying to match "sip:1.2.3.4:5061;transport=tls" from dispatcher module to "1.2.3.4:5061" from tls.cfg. Any help or advice would be appreciated Regards Pete

setflag and hash table variables

by Asgaroth

I originally sent this to sr-dev in error, I am resending to sr-users instead, thanks Hi All, Quick question, is it possible to use variables in the setflag function, I am trying to set a flag that is stored in a hash table using the setflag function, but I keep getting syntax errors. I am using kamailio 4.3.3. Here's what I am trying to do: htable core_setid defines a dispatcher setid key and its value is associated with a flag as follows: id:key:key_type:value_type:value:expires 1:102:0:1:7:0 so, simple hash table type with an integer key of value 7 and no expiry In dispatcher I have the following modparams set, so that ds_is_from_list() will set them if found: modparam("dispatcher", "setid_pvname", "$var(ds_setid)") modparam("dispatcher", "attrs_pvname", "$var(ds_setid_attrs)") Then in my routing logic I have the following code block: if ( ds_is_from_list() ) { if ( $sht(core_setid=>$var(ds_setid)) != $null ) { setflag( $sht(core_setid=>$var(ds_setid)) ); return; } else { send_reply("403", "No flag set for source"); exit; } } When I test this using kamailio -c -f <filename> I get the following error: 0(20629) : <core> [cfg.y:3432]: yyerror_at(): parse error in config file /shared/kamailio/etc/routing_logic.cfg, line 175, column 21-52: syntax error 0(20629) : <core> [cfg.y:3432]: yyerror_at(): parse error in config file /shared/kamailio/etc/routing_logic.cfg, line 175, column 21-52: missing '(' or ')'? 0(20629) : <core> [cfg.y:3432]: yyerror_at(): parse error in config file /shared/kamailio/etc/routing_logic.cfg, line 175, column 21-52: bad command: missing ';'? 0(20629) : <core> [cfg.y:3435]: yyerror_at(): parse error in config file /shared/kamailio/etc/routing_logic.cfg, line 175, column 53: bad command ERROR: bad config file (4 errors) If I change the setflag line to setflag(7), then I dont get the error. I was wondering if its possible to have hashtable variables as parameters to the setflag function, or am I going about this in the wron way. Any thoughts would be appreciated. Thanks

Kamailio vs RTPEngine Performance

by M S

Hi, I was asked some interesting questions yesterday by a rather techy client related to Kamailio and RTPEngine performance. Q1: For Kamailio we have say 8 child processes, which means there are 8 threads per listen address to process sip messages, i.e. for example 8 INVITE messages at any instance of time can be processed by Kamailio. If say, one INVITE takes 200ms to be processed and send out to destination, then we can estimate processing power of kamailio to be 40 INVITE requests per second per listen address, right? Q2: If so, then assuming each INVITE requires to engage RTPEngine. How can we ensure that RTPEngine would be capable to handle these 40 INVITE requests? The only relevant parameter I see in RTPEngine daemon script is "NUM_THREADS" (default value 5). What does this represent? Does this analogs to children as in Kamailio? Q3: How does RTPEngine manages SRTP <=> RTP translation (e.g. if one endpoint is WebRTC and other is traditional SIP)? My understanding is that RTPEngine has a kernel module (assuming kernel module is installed) which also manages this conversion besides forwarding the media packets. The Linux kernel already has encoders / decoders for nearly all encryption algorithms which are utilized by RTPEngine for doing the conversion in kernel space, right? if not then how it is done? Q4: Continuing to Q2, If these NUM_THREADS process actual media packets (RTP or SRTP) then are these synchronous or asynchronous? I think these are asynchronous, just want to confirm (otherwise RTPEngine won't process more then e.g. 5 calls at a time). So, assuming asynchronous how many packets can be queue to each thread? This would help estimating RTPEngine throughput using various codecs in calls. (e.g. assuming G.711 codec we have 50pps, if each thread queue size is 1000 then each thread can process 1000/50=20 concurrent calls and whole RTPEngine would process 20x5=100 concurrent calls). Thank you.

evapi tcp parsing??

by Jayesh Nambiar

Hello, I'm exploring the evapi module for my kamailio to interface with an external node.js app for third party stuff like AAA, billing engine tasks, notifications and so on. I followed and took some ideas from the rtjson and evapi tutorial found here( http://kb.asipto.com/kamailio:k43-async-sip-routing-nodejs) to build the node.js app consuming events. When I stress tested the scenario using SIPp and tried sending a lot of events at 300-350cps from Kamailio, I noticed that at times the client is receiving 2-3 events in a single message together although I do event_sync_relay once per SIP message received and have netstrings enabled. I believe this is a typical behavior of TCP and needs to be handled by the client using some kind of Netstring handler. Please correct me if I'm wrong. And hence I'd like to know what particularly needs to be taken care of while writing a client that is listening for events on raw tcp socket and how does kamailio handle this situation while receiving messages over TCP socket?? Does kamailio recognize the end of netstring properly on evapi:message-received and give exactly one message to take care of on every "message-received" event or should that be handled in the script somewhere !! I also referred cgrates client over evapi example which is written in GO, but I couldnt find them handling TCP streams clearly either. I'd really appreciate some expert suggestion here to make an informed decision on using the evapi module for a large scale solution. Thanks, - Jayesh
