Kamailio 5.3.8 and RTPengine 9.4.1.1+0~mr9.4.1.1
by Mihai Cezar 23 May '21

23 May '21

Hi All, I've been using Kamailio as a proxy for asterisk (with public ips), everything was fine until i've changed the setup to private ips for asterisk. What I did so far: - Kamailio and rtpengine are on a box with 1 public IP. - Asterisk containers on private ips each asterisk has 2 trunks ( 1trunk voip provider 1trunk the Proxy). What works: - Proxy registrations and sip signaling works. What it does not work: - On the asterisk I got only on rtp connexion, my guess is that has something to do with the SDP, asterisk put the private ip in the SDP header. RTPengine is configured using this guide https://github.com/sipwise/rtpengine Can you have a look at the kamailio config, i think i am missing something or do something wrong. Thank you! command to start was: rtpengine --table=42 --listen-ng=127.0.0.1:2223 --interface=public/110.20.20.1 --tos=184 --pidfile=/run/rtpengine.pid --no-fallback and the Kamailio cfg is this: #!KAMAILIO #!define FLT_ACC 1 #!define FLT_ACCMISSED 2 #!define FLT_ACCFAILED 3 #!define FLT_FS 10 #!define FLT_NATS 5 #!define FLB_NATB 6 #!define FLB_NATSIPPING 7 #!define WITH_DEBUG #!define WITH_NAT ## This is the main configuration file for our proxy! ####### Global Parameters ######### #!ifdef WITH_DEBUG debug=4 memdbg=5 memlog=5 log_stderror=yes disable_core_dump=no sip_warning=yes #!else debug=-0 log_stderror=no sip_warning=no disable_core_dump=yes #!endif log_facility=LOG_LOCAL0 fork=yes children=8 auto_aliases=no port=5060 disable_tcp=yes server_id = 1 server_signature=yes server_header="Server: proxy" dns_try_ipv6=no dns_try_naptr=no dns_retr_time=1 dns_retr_no=1 rev_dns=no ####### Modules Section ######## #loadmodule "db_mysql.so" loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "acc.so" loadmodule "dispatcher.so" loadmodule "path.so" loadmodule "nathelper.so" loadmodule "rtpengine.so" ####### Modules Settings # ----------------- setting module-specific parameters --------------- modparam("xlog", "buf_size", 4096) modparam("xlog", "prefix", "xlog: ") modparam("xlog", "log_facility", "LOG_DAEMON") modparam("xlog", "log_colors", "L_ERR=cr") modparam("xlog", "log_colors", "L_ERR=cr;L_WARN=px") # ----- jsonrpcs params ----- modparam("jsonrpcs", "pretty_format", 1) # ----- tm params ----- modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) # ----- rr params ----- modparam("rr", "enable_full_lr", 1) modparam("rr", "append_fromtag", 0) #!ifdef WITH_NAT modparam("nathelper", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@proxy") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:2223") modparam("rtpengine", "rtpengine_retr", 2) modparam("rtpengine", "hash_table_size", 256) modparam("rtpengine", "hash_table_tout", 600) #!endif # ----- registrar params ----- modparam("registrar", "method_filtering", 1) modparam("registrar", "append_branches", 0) modparam("registrar", "max_expires", 3600) modparam("registrar", "gruu_enabled", 1) # ----- acc params ----- modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 0) modparam("acc", "detect_direction", 0) modparam("acc", "log_flag", FLT_ACC) modparam("acc", "log_missed_flag", FLT_ACCMISSED) modparam("acc", "log_extra", "src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;src_ip=$si") modparam("acc", "failed_transaction_flag", FLT_ACCFAILED) # ----- dispatcher params ----- modparam("dispatcher", "list_file", "/etc/kamailio/plugins/dispatcher.list") modparam("dispatcher", "xavp_dst", "_dsdst_") modparam("dispatcher", "xavp_ctx", "_dsctx_") modparam("dispatcher", "ds_ping_from", "sip:ping@proxy") modparam("dispatcher", "ds_probing_mode", 1) modparam("path", "use_received", 1) ####### Routing Logic ########### # main request routing logic request_route { # per request initial checks route(REQINIT);

Can Kamailio help with this?
by Antony Stone 22 May '21

22 May '21

Hi. I've been aware of Kamailio, and on this list, for several years, but so far I have not implemented Kamailio for any purpose. I wonder if it could be a suitable tool for the following scenario. I currently use Asterisk to register as a client, with username and password, to other SIP PBXs in order to receive calls. As far as the other PBX is concerned, Asterisk looks like a SIP telephone on a particular extension. However, Asterisk's SIP client capabilities are limited to handling phone calls only, and it specifically cannot receive presence information about the state of other extensions from the remote PBX. So, could Kamailio be used in the path between Asterisk and the remote PBX so that the registration on the PBX comes from Kamailio (with any incoming calls being passed to Asterisk), but with Kamailio also receiving presence information from the remote PBX and making this available to some script or application (which I would expect to have to write)? The main point is that I don't want to have two things registering to the remote PBX, one for calls and one for presence, so I'm looking for a way to register with something which understands presence, and can also pass calls on to Asterisk. Can anyone suggest whether Kamailio could do this, and if so, point me at some resources to help me get started; or alternatively suggest ideas on some other tool which might be more appropriate than Kamailio? Thanks for any ideas, Antony. -- Schrödinger's rule of data integrity: the condition of any backup is unknown until a restore is attempted. Please reply to the list; please *don't* CC me.

Kamailio Stop Processing Call
by M Arqum CH 21 May '21

Hello Members, I have kamailio setup backed with mysql db, using db_cluster module for spliting read and write.. Lisiting on three different virtual ips are bind with same/single udp port *1* for processing calls. One static IP is bind with udp port*2* to for processing/response to option messages send from keepalived external script after every few seconds and for DMQ messages from other kamailio node. General configuation details: children=16 fork=yes listen=udp:VIP:SIP_PORT1 listen=udp:VIP2:SIP_PORT1 listen=udp:VIP3:SIP_PORT1 listen=udp:StaticIP3:SIP_PORT2 listen=tcp:SIP:RPC_PORT SH_MEM=5012 PRIV_MEM=264 System Specification : 24 GB RAM, 12 CPUs Sometimes kamailio radomly stop processing the requests or give no response on new requests recevied on virtual ips and as well it did't show any error in syslog. To monitor the kamailio memory I used promethues ( https://github.com/florentchauveau/kamailio_exporter) The moment kamailio stop processing the requests it also stop responding to kamailio exporter and scrap request get timeout. i.e error log on console debian prometheus-kamailio-exporter[83440]: 2021/05/20 12:15:27 [error] cannot read header: read unix @->/tmp/kamailio__ctl: i/o timeout After getting first timeout occurrence of kamailio-exporter scrap request, kamailio processed sip messages for almost 30 seconds then completly stop replying to any message. But it keep replying to option message arrive on different port from keepalived script.

Video transcode for doorbell
by Luke Kenny 21 May '21

21 May '21

I have a SIP video doorbell device that is only capable of sending H264 and MJPEG video. The site is using 3CX and its associated mobile app, which only supports VP8 and VP9. Without properly reading the documentation, I went ahead and set up kamailio and rtpengine to sit in between the doorbell and 3CX. I has assumed rtpengine was capable of transcoding video as well as audio, however upon proper inspection it appears that isn't the case. Is there a kamailio module that is capable of video transcoding, even if it isn't real time, or at a reduced framerate? As the application is a doorbell, it doesn't need to be perfect. Many thanks, Luke Kenny

Eternal config - Kamailio and rtpengine

Hi! I use lxc containers with asterisk wich their are connecting to kamailio, so far so good they work when i put the containers with public ips, but when i switched to private ip I have one-way audio. I tried to with rtpengine but no luck: rtpengine --table=42 --listen-ng=127.0.0.1:2223 --interface=56.12.19.100 --tos=184 --pidfile=/run/rtpengine.pid --no-fallback --log-level=7 --log-facility=local3 the setup looks like this: VM-KAMAILIO-(public ip 56.12.19.100 with static routes for the private IP) --> LxC(n) (with private class 192.168.0.n) The problem i think is when LxC asterisk is sending back the 200 OK from Invite it puts his private ip in the sdp filed: v=0 o=- 2171376102 3 IN IP4 192.168.0.2 s=Asterisk c=IN IP4 192.168.0.2 t=0 0 m=audio 11336 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=maxptime:150 a=sendrecv i've loaded the modules, but after this i am stuck.... loadmodule "nathelper.so" loadmodule "rtpengine.so" modparam("nathelper", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@proxy") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) modparam("rtpengine", "rtpengine_sock", "udp:localhost:2223") modparam("rtpengine", "rtpengine_retr", 2) modparam("rtpengine", "hash_table_size", 256) modparam("rtpengine", "hash_table_tout", 600)

Permissions sometimes does not find group
by Romain Untereiner 19 May '21

19 May '21

Hello all, I am having some trouble with Permissions module of Kamailio, regarding the allow_source_address_group() function. In 99.9% of the cases the IP of our partner is allowed as expected, but randomly it can fail (returning -1 for the same IP address that was allowed for many other calls in the meantime). I can’t understand why it fails and why only « sometimes » - I confirm this append on the same Kamailio box, with same IP and Port of the partner. In my custom logs: « X.X.X.X:YYYY is allowed through group Z » —> as expected and sometimes (like 1% of the cases): « X.X.X.X:YYYY is not allowed - allow_source_address_group returned -1» It is maybe to note that in the address table, this range is defined as /24 and not /32. Until now it never happened on /32 defined address but I don’t know if it can be correlated. Would someone have a clue on this? Versions: - kamailio 5.5.0 (x86_64/linux) d4c1a1 - debian 9 stretch - postgresql 11.7 Many thanks! Romain Untereiner Co founder at Cantoo www.cantoo.co
