using APP_LUA for complex arithmetic operations
by Jayesh Nambiar 03 Dec '15

03 Dec '15

Hi, I understand that kamailio does not allow float-point values in variables and I think kamailio is not a great place to do complex arithemtic operations and so I thought of using app_lua for the same. So can I pass the control to app_lua and come back to config script with some values? For eg. can I call a lua script that does a complex arithemetic operation on my AVP values and based on certain conditions; return back a true or false and then I continue in my existing script. I came across an exmaple http://kb.asipto.com/kamailio:usage:k32-lua-routing but this is more like doing the entire thing inside LUA. What I'm looking at is getting certain things done in lua and continue the script processing. Thanks for any help here. - Jayesh

Kamailio - Asterisk, problem with SIP trunk mode
by Mickael MONSIEUR 02 Dec '15

02 Dec '15

Hello, First, i have 7 years experience with Asterisk, but I started a project with Kamailio, forgive me in advance if I say silly things...! ;-) I set up a classic Asterisk / Kamailio configuration: sip phones -> kamailio -> asterisk -> sip trunks/pstn. When a call comes from the PSTN side, if I configure Asterisk as follows: [012345678] type = friend username = 012345678 secret = xxxxxxx host = dynamic fromdomain = sip.mydomain.com fromuser = 012345678 Standard mode: exten => 012345678, 1, Dial(SIP/012345678) -> The call is redirected on the phone by Kamailio ! :-) ------------------------------------------------------------------------------------------------------------------------------------------------ Trunk mode: [mytrunk] type = friend username = mytrunkUser secret = xxxxxxx host = dynamic fromdomain = sip.mydomain.com fromuser = mytrunkUser exten => 012345678, 1, Dial(SIP/mytrunk/012345678) -> The call is rejected by Kamailio.... exten => 012345679, 1, Dial(SIP/mytrunk/012345679) -> The call is rejected by Kamailio .... My question is how to allow the routing of multiple numbers (trunk mode) in a SIP account with Kamailio? Best regards, Mickael

Record-route on sequential requests
by Kristian F. Høgh 01 Dec '15

01 Dec '15

Hi list, Record-route on sequential requests doesn't have did/vsf parm. On initial INVITE, I call record_route() and set dialog flag. kamailio adds the following RR Record-Route: <sip:ww.xx.yy.zz;lr;ftag=15af612df;vsf=AAAA....;did=4a8.3ca2> UAC sends a re-INVITE, containing the following route: Route: <sip:178.21.251.54;lr;ftag=15af612df;vsf=AAAA....;did=4a8.3ca2> I call loose_route() followed by record-route(), and kamailio adds the following RR: Record-Route: <sip:ww.xx.yy.zz;lr;ftag=15af612df> I've got a phone which updates the routeset on sequential requests (which I don't think it should) and the did-matching fails. Should kamailio add did/vsf on sequential requests, when I call record_route()? Should I set dlg_match_mode to 1? (I use 0) Is it wrong to call record_route() from sequential requests? Which way is the best to resolve the problem? Regards, Kristian Høgh Uni-tel A/S

Problem with NATed UAC
by Vladimir Stepic 01 Dec '15

01 Dec '15

Hello everyone, this is my first message. I'm glad to become a part of this big community. I'm new in SER technology. I worked in Asterisk PBX only, until now. For the first time i installed Elastix MT witch have kamailio in front of asterisk, and now i have a problem. I attach a diagram of initial configuration in my lab and pcap file and kamailio.cfg. Regardless diagram, x.x.x.x addresses are public and y.y.y.y are private. When i test connection 1.1 is working, connection 1.2 not working connection 2.2 not working connection 1.3 not working connection 2.3 working Phones are connected(authenticate) to kamailio, but when i look at asterisk cli those phones are unreachable, but can call, but can not be called. On router where android works, Siemens dont, and where pc softphone works other UAC dont work. I think that my nat-traversal configure good, regardless of documentation. Please tell me, if someone has some ideas of solve this problem. Thanks in advance, and sorry for my bad english :) ---------------------------------------------------------------------- *Vladimir Stepić,* Engineer specialist in computer networking System Linux Administrator mob. tel. +381 69/18-68-431 email: e1.e398(a)gmail.com

kamailio's Makefile system : Enabling CFLAGS/LDFLAGS for udp_server.c
by aft 01 Dec '15

01 Dec '15

Hi, I'm doing some experimentation on kamailio's udp_server.c. Now i need libpcre for that. So i first thought if i enable the regex module, the CFLAGS/LDFLAGS would be available from udp_server.c. But it turns out it doesn't build(doesn't *link* to be more precise). Kamailio's build system is pretty unfamiliar for me. Although i absolutely hate autotools based build system(I prefer Scons), but i'm pretty familiar with these. But Kamailio's build system is pretty much cryptic for me(Is it based on CMake?). There is a page on devel wiki for kamailio's build system. it turns out i can do stuff like : make cfg prefix=/opt/kamailio \ SCTP=1 \ CC_EXTRA_OPTS=-I/usr/gnu/include \ group_include="standard postgres presence" \ include_modules="snmpstats lcr tls" So there might be a LD_EXTRA_OPTS or stuff like that. Which than would be defined (I guess) globally so the core c files(like udp_server.c) would be able to use that. One way i guess would be to sharpen my egrep and find that variable name. But it all feels a bit hacky. As i have already included regex module, there should be a way to reuse the CFLAGS/LDFLAGS for that module for core files like udp_server.c. Cheers Arif

Daniel, I got the following error message (currently running version 4.3): Nov 27 18:56:51 ip-10-1-2-100 /usr/local/sbin/kamailio[451]: ERROR: dispatcher [dispatcher.c:517]: mod_init(): call load dispatching DST ID_AVP set but no size for hash table Nov 27 18:56:51 ip-10-1-2-100 /usr/local/sbin/kamailio[451]: ERROR: <core> [sr_module.c:962]: init_mod(): Error while initializing modul e dispatcher (/usr/local/lib64/kamailio/modules/dispatcher.so) I noticed in the following DEV GIT (Version 3.1) message that the error message was changed to a message that more clearly defined the error and correction for it. But the my current message would indicate that it got changed back to the older error message. http://lists.sip-router.org/pipermail/sr-dev/2010-November/009799.html Just thought I would point it out because the newer message from the GIT message seems clearer to me. -- *Sam D Ware* CIO *Vera Networks LLC* Email: sam.ware(a)veranetworks.com

crash on using the $expires variable
by Jayesh Nambiar 28 Nov '15

28 Nov '15

Hi, I am trying to extract out the expires value from the incoming REGISTER request. It might be present in the Contact header or as a separate Expires header and hence I planned to use the $expires(max) PV to get this. But kamailio just crashes as soon as I use the variable. Here's when it crashes: if(is_method("REGISTER")) { xlog("L_INFO", "Expires is $expires(max)"); if(!save("location", "0x01")) { t_reply("500", "Error while saving AOR"); } } It crashes at the xlog point.

restore_uri_reply() called twice in 200OK to BYE
by Efelin Novak 27 Nov '15

27 Nov '15

Hi Folks, I have a problem with To and From headers in 200 OK to BYE request. Their URI is doubled when leaving Kamailio. Incoming 200 OK: From : <sip:00421111@IP_ADDRESS>;tag=as017a2986 To : <sip:00421222@IP_ADDRESS0>;tag=K7ryDgH2g7gFm Outgoing 200 OK: From : <sip:+421111@IP_ADDRESS><sip:+421111@IP_ADDRESS>;tag=as017a2986 To : <sip:+421222@IP_ADDRESS><sip:+421222@IP_ADDRESS>;tag=K7ryDgH2g7gFm I'm using uac module to replace these headers in auto and dialog mode: modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) append_fromtag is also set: modparam("rr", "append_fromtag", 1) When I run kamailio in debug mode I can see the function restore_uri_reply() is called twice: . . . 0(3133) DEBUG: <core> [parser/parse_via.c:1284]: parse_via_param(): Found param type 234, <received> = <IP_ADDRESS>; state=6 0(3133) DEBUG: <core> [parser/parse_via.c:1284]: parse_via_param(): Found param type 232, <branch> = <z9hG4bK0bb8c5b2>; state=6 0(3133) DEBUG: <core> [parser/parse_via.c:1284]: parse_via_param(): Found param type 235, <rport> = <5060>; state=16 0(3133) DEBUG: <core> [parser/parse_via.c:2672]: parse_via(): end of header reached, state=5 0(3133) DEBUG: <core> [parser/msg_parser.c:513]: parse_headers(): parse_headers: Via found, flags=62 0(3133) DEBUG: <core> [parser/msg_parser.c:526]: parse_headers(): parse_headers: this is the second via 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:176]: parse_to_param(): DEBUG: add_param: tag=teHD72X67aQUm 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:898]: parse_addr_spec(): end of header reached, state=29 0(3133) DEBUG: <core> [parser/msg_parser.c:190]: get_hdr_field(): DEBUG: get_hdr_field: <To> [60]; uri=[sip:421222@IP_ADDRESS:5060] 0(3133) DEBUG: <core> [parser/msg_parser.c:192]: get_hdr_field(): DEBUG: to body [<sip:421222@IP_ADDRESS:5060>] 0(3133) DEBUG: <core> [parser/msg_parser.c:170]: get_hdr_field(): get_hdr_field: cseq <CSeq>: <103> <BYE> 0(3133) DEBUG: tm [t_lookup.c:949]: t_reply_matching(): DEBUG: t_reply_matching: hash 10806 label 0 branch 0 0(3133) DEBUG: tm [t_lookup.c:1004]: t_reply_matching(): DEBUG: t_reply_matching: reply matched (T=0x220071b4)! 0(3133) DEBUG: tm [t_hooks.c:288]: run_trans_callbacks_internal(): DBG: trans=0x220071b4, callback type 2, id 0 entered 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:176]: parse_to_param(): DEBUG: add_param: tag=as46bccb83 0(3133) DEBUG: <core> [parser/parse_addr_spec.c:898]: parse_addr_spec(): end of header reached, state=29 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421222@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421222@IP_ADDRESS>> 0(3133) DEBUG: tm [t_hooks.c:288]: run_trans_callbacks_internal(): DBG: trans=0x220071b4, callback type 2, id 0 entered 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421111@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:705]: restore_uri_reply(): removing <<sip:00421222@IP_ADDRESS>> 0(3133) DEBUG: uac [replace.c:714]: restore_uri_reply(): inserting <<sip:+421222@IP_ADDRESS>> . . . I think the problem is in registering a function restore_uris_reply() in callbacks in functions (both in replace.c of uac module) * void rr_checker(struct sip_msg *msg, str *r_param, void *cb_param) * static void replace_callback(struct dlg_cell *dlg, int type, struct dlg_cb_params *_params) Both of these callbacks are registered for BYE and ACK requests (INVITE request is using different callback), therefore running restore_uri_reply() twice. For testing purposes after I have removed the callback in rr_checker and recompile the uac module, To and From headers were OK. In my configuration I'm calling uac_replace_to in RELAY route: route[RELAY] { if ( !has_totag() ) { dlg_manage(); uac_replace_to("$ru"); } if (!t_relay()) { sl_reply_error(); } } So I think there is a bug in uac module, when one function is registered twice in callbacks for NON-INVITE requests. Or is there a problem with my configuration script? Can anyone point me to the direction how to solve this issue? Thank you Efelin Kamailio version: kamailio 4.4.0-dev6 (i386/linux) a66e22-dirty

2 Kamailio servers on same domain
by Michael Nielsen 26 Nov '15

26 Nov '15

I've installed Kamailio on 2 different servers. They share the same PostgreSQL database for users etc. I've setup a single domain, sip.my-domain.com, with latency responds to the 2 servers. So a user will always land on the server with the fastest responds in a respective area of the world. However, it seems as if 2 users are registered on different Kamailio servers - even though they share the same database - they cannot call each other? Have I misunderstood something? I've enabled WITH_NAT.

[CFP] reminder! FOSDEM RTC dev-room talks: deadline Friday
by Daniel Pocock 25 Nov '15

25 Nov '15

Reminder: speaker's deadline this Friday, 27 November at 23:59 UTC We have already received several really exciting talk proposals but there is still time for people to propose talks or encourage friends or colleagues to speak. Many other dev-rooms also have a deadline in the next few days and if your topic is applicable to more than one dev-room, you are welcome to make more than one submission. Please contact us or put a note in the memo field at the top of the talk proposal if you do that. All projects are encouraged to consider making a lightning talk too, it is an excellent opportunity to get exposure for your project: even though you only have 15 minutes, it can be a much larger and more diverse audience than in some dev-rooms. For full details, please see the call for papers: http://danielpocock.com/fosdem-2016-free-rtc-dev-room-and-lounge We invite all potential speakers and participants to discuss the selection process and other aspects of FOSDEM on the Free-RTC mailing list: https://lists.fsfe.org/mailman/listinfo/free-rtc

TLS not enough memory issue with git master
by Anthony Messina 25 Nov '15

25 Nov '15

I have noticed the following issue which began with builds somewhere between git master commits bff0a08 and 6173ef7. I did not see this issue with my previous builds and haven't been able to pin down the problem, which is why I haven't formally filed a bug. Any help or guidance is appreciated, because this has crippled my use of Kamailio. Only a restart enables it to work again until the issue recurs. ERROR: tls [tls_server.c:189]: tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: 8870536 ERROR: <core> [tcp_read.c:1303]: tcp_read_req(): ERROR: tcp_read_req: error reading I currently build against and run openssl-1.0.1k-12.fc22.x86_64. I have a very small operation and the only change on the operational side is that all 5 of my mobile UACs (yes, that's all) have switched from CSipSimple/Android to Zoiper/Android, which doesn't yet have support for client-side certificates so verify_certificate and require_certificate are off for both the server and client config. The server is started with: /usr/sbin/kamailio -P /run/kamailio/kamailio.pid -m 64 -M 8 I have tried modifying the shared mem to 128 but the issue still occurs. Even right now, I am seeing the error when only one UAC has established a TLS connection: # kamcmd tls.list { id: 572 timeout: 3475 src_ip: 10.77.79.156 src_port: 58688 dst_ip: 10.77.79.3 dst_port: 5061 cipher: ECDHE-RSA-RC4-SHA SSLv3 Kx=ECDH Au=RSA Enc=RC4(128) Mac=SHA1 ct_wq_size: 0 enc_rd_buf: 0 flags: 2 state: established } # kamailio.cfg enable_tls=yes loadmodule "tls.so" modparam("tls", "connection_timeout", 60) #modparam("tls", "tls_log", 1) #modparam("tls", "tls_debug", 1) #modparam("tls", "low_mem_threshold1", -1) #modparam("tls", "low_mem_threshold2", 0) modparam("tls", "session_cache", 1) # tls.cfg [server:default] method = TLSv1+ verify_certificate = no require_certificate = no private_key = /etc/kamailio/example.org.key.pem certificate = /etc/kamailio/example.org.crt.pem server_name = example.org cipher_list = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA- AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-RC4-SHA:ECDHE-RSA-AES256- SHA:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-GCM- SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:RC4- SHA:AES256-GCM-SHA384:AES256-SHA256:CAMELLIA256-SHA:ECDHE-RSA-AES128- SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:CAMELLIA128- SHA:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK [client:default] method = TLSv1+ verify_certificate = no require_certificate = no private_key = /etc/kamailio/example.org.key.pem certificate = /etc/kamailio/example.org.crt.pem cipher_list = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA- AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-RC4-SHA:ECDHE-RSA-AES256- SHA:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-GCM- SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:RC4- SHA:AES256-GCM-SHA384:AES256-SHA256:CAMELLIA256-SHA:ECDHE-RSA-AES128- SHA:AES128-GCM-SHA256:AES128-SHA256:AES128-SHA:CAMELLIA128- SHA:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK Thanks. -Anthony -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Kamailio/RTPProxy incorrect port 0
by Igor Potjevlesch 25 Nov '15

25 Nov '15

Hello, I can't figure out why Kamailio reports hundreds of calls with the following error: "/usr/local/sbin/kamailio[2997]: ERROR: rtpproxy [rtpproxy.c:2727]: force_rtp_proxy(): incorrect port 0 in reply from rtp proxy" It seems that each time this error occurs, we got a one-way audio call. I already check and increase the limit for opening files that the process can open with ulimit -n 500000. But, anyway, if I look to /proc/$PID/fd, I never see more than 1000 files open. I also check the socket with netstat: same; I can see the error while there's only less than 800 sockets open. Is someone know what can be the trigger of this? Regards, Igor.
