Hi, I configured the kamailio with rtpengine and the calls betwwn webrtc-clients and sip-clients working fine, Does rtpproxy supports the webrtc, and is there any additional configuration is required.

Releasing v5.0.7

by Daniel-Constantin Mierla

Hello, I am considering to release Kamailio v5.0.7, out of git branch 5.0, sometime next week, likely to happen on Thursday, June 21. As usual, if there is any issue not reported yet on github, do it a soon as possible to have a chance to investigate. Soon I will review and backport the commits that apply from branch 5.1 back to 5.0, so keep an eye and notify us if a patch you expect to be in 5.0 is not backported. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference -- www.kamailioworld.com

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

Kamailio IMS PCSCF database problem

by tyd

Dear sir, I'm using Kamailio 4.4.0 and 5.1.4 IMS module. During using SIPp 3000 subscriber register testing, after enabling PCSCF DB URL function, the contents of 3000 subscribers on PCSCF location table are the same. Using the same IP address and UDP port of 3000 SIPp REGISTER message seems to be the problem. Anyone can help me? Thanks a lot.

KEMI routing script Python exceptions with empty traceback

by Michael Loughrey

Hi All, I'm using app_python with a KEMI Python routing script. I have been getting occasional Python exception error logs : kamailio[2242]: 8(2253) ERROR: app_python [python_support.c:150]: python_handle_exception(): python_exec2: Unhandled exception in the Python code: kamailio[2242]: TypeError: an integer is required The scripts seems to function without an issue but these error logs appear fairly frequently, always with an empty Python stack trace. I am running Kamailio 5.1 on a Debian 9 system and using Python 2.7 : >>:/usr/local/etc/kamailio# python --version Python 2.7.13 >>:/usr/local/etc/kamailio# kamailio -v version: kamailio 5.1.4 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, 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, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 18:56:43 Jun 8 2018 with gcc 6.3.0 I have also tried using a Kamailio load built from the master branch (commit f8b8cecb) which gives enhanced exception logging identifying the function an exception occurs within and parameters. I see this occurring in different parts of the routing script e.g. from script def ksr_onsend_route(self,msg): KSR.xlog.xdbg("ONSEND_ROUTE fs=[$fs] $mb\n"); return 1; an exception is reported within ksr_onsend_route() even when the log level is info. Changing log to xlog.xinfo, the log is seen to be sent to syslog but again the exception is reported. These exceptions are always "TypeError: an integer is required" but don't seem related to the Python script. Here is an example of the log with a patch applied to to Kamailio 5.1 to show the function the exception is reported within. kamailio[14092]: 6(14103) ERROR: app_python [python_support.c:156]: python_handle_exception(): apy_exec: ksr_reply_route((null)): Unhandled exception in the Python code: kamailio[14092]: TypeError: an integer is required . . . kamailio[14092]: 22(14119) INFO: <script>: ONSEND_ROUTE fs=[udp: 10.0.31.126:5080] ACK sip:10008@media.test.io:5061;transport=TLS SIP/2.0 . . . . kamailio[14092]: 22(14119) ERROR: app_python [python_support.c:156]: python_handle_exception(): apy_exec: ksr_onsend_route((null)): Unhandled exception in the Python code: kamailio[14092]: TypeError: an integer is required Has anyone got an idea what can be causing these exceptions and how to avoid them? Currently I have simply patched the load to drop the level of this log to debug when such an exception occurs with an empty traceback as they seem spurious. Cheers Mike

Installing RTPengine on CentOS 7

by Francisco Valentin Vinagrero

Hi, I'm trying to install RTPengine in the same machine as I have Kamailio, running CentOS 7, but there are a few dependencies that yum cannot seem to resolve and I that cannot find anywhere else. As soon as I try to build the daemon it produces these errors: make[1]: Leaving directory `/usr/local/src/rtpengine/daemon' Failed build with ../lib/fix_frame_channel_layout-01.h Trying build with ../lib/fix_frame_channel_layout-02.h make[1]: Entering directory `/usr/local/src/rtpengine/daemon' rm -f "resample.c" echo '/******** GENERATED FILE ********/' > "resample.c" cat ../lib/"resample.c" >> "resample.c" Package libevent_pthreads was not found in the pkg-config search path. Perhaps you should add the directory containing `libevent_pthreads.pc' to the PKG_CONFIG_PATH environment variable No package 'libevent_pthreads' found Package libavcodec was not found in the pkg-config search path. Perhaps you should add the directory containing `libavcodec.pc' to the PKG_CONFIG_PATH environment variable No package 'libavcodec' found Package libavformat was not found in the pkg-config search path. Perhaps you should add the directory containing `libavformat.pc' to the PKG_CONFIG_PATH environment variable No package 'libavformat' found Package libavutil was not found in the pkg-config search path. Perhaps you should add the directory containing `libavutil.pc' to the PKG_CONFIG_PATH environment variable No package 'libavutil' found Package libswresample was not found in the pkg-config search path. Perhaps you should add the directory containing `libswresample.pc' to the PKG_CONFIG_PATH environment variable No package 'libswresample' found Package libavfilter was not found in the pkg-config search path. Perhaps you should add the directory containing `libavfilter.pc' to the PKG_CONFIG_PATH environment variable No package 'libavfilter' found So, in the end, at least 'libevent_pthreads','libavcodec', 'libavformat', 'libavutil', 'libswresample' and 'libavfilter' are missing. Trying to install them one by one with yum fails because it cannot find these packages for CentOs 7. Can anyone point me to a solution for this? Thanks, Francisco.

Re: [SR-Users] Textops Regex

by Duarte Rocha

You're right, it is application/sdp and the back slash works as escape character. However, a new problem came. I'm using this, since someone upstream is adding \r\n to a part of the body : replace_body_all("application\/sdp\r\n\r\n", "application/sdp\r\n"); The regex finds the application/sdp just right, but doesn't replace everything. So, as a final result i get applicationapplication\sdp\r\n. Is this intended? Thanks for your help

SIP Notify use UDP instead TCP

by denislav.tsonev＠musala.com

Hello, I'm trying to configure Kamailio 5.1 like "presence" server. Pretty much with default settings of kamailio: # ----- presence params ----- modparam("presence", "db_url", DBURL) ;modparam("presence", "server_address", "sip:10.0.6.226:5060" ) modparam("presence", "send_fast_notify", 0) modparam("presence", "db_update_period", 20) modparam("presence", "clean_period", 40) modparam("presence", "subs_db_mode", 2) modparam("presence", "fetch_rows", 1000) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) # ----- presence_dialoginfo params ----- modparam("presence_dialoginfo", "force_single_dialog", 0) # ----- pua params ----- modparam("pua", "db_url", DBURL) modparam("pua", "db_mode", 2) modparam("pua", "update_period", 60) modparam("pua", "dlginfo_increase_version", 0) modparam("pua", "reginfo_increase_version", 0) modparam("pua", "check_remote_contact", 1) modparam("pua", "fetch_rows", 1000) # ----- pua_dialoginfo params ----- modparam("pua_dialoginfo", "include_callid", 1) modparam("pua_dialoginfo", "send_publish_flag", FLT_DLGINFO) modparam("pua_dialoginfo", "caller_confirmed", 0) modparam("pua_dialoginfo", "include_tags", 1) modparam("pua_dialoginfo", "override_lifetime", 124) # ----- dialog params ----- modparam("dialog", "db_url", DBURL) modparam("dialog", "enable_stats", 1) modparam("dialog", "db_mode", 1) modparam("dialog", "dlg_flag", FLT_DLG) And when UDP transport is using, everything works perfect. But when TCP is using (only "listen: tcp:IP:5060" is set) NOTIFY is not send. When "listen: tcp:IP:5060" and "listen: udp:IP:5060" I receive NOTIFY but through UDP.
