Hi, I tried advertising udp port like this listen=udp:192.168.1.x:5060 advertise 182.70.xx.yy:5060. How to advertise RTP ports? Kamailio+RTPengine on a Centos s/m with a priv ip - 192.168.1.x Asterisk is on another CentOs s/m with a priv ip - 192.168.1.y pfsense on pub ip - 182.75.xx.yy PORT FORWARDING on pfsense- sip and rtp ports to kamailio+rtpengine server 192.168.1.x. Config and logs are attached. Thank you for the reply! With Regards, Arish Haque

htable 1 Millon registers
by Mauricio Tejeda 23 Oct '18

23 Oct '18

Good afternoon. Trying to use the htables module to load an extensive table in memory, I can not start kamailio. If the table contains few records (5 and 10 in my examples), this works without problems, for everything else I lose the connection to the database "Lost connection to MySQL server during query" I modified the timeout of mariadb but I can not work. Someone with a similar problem or ideas on how to solve it? Thank you

RTPEngine set IDs
by Alex Balashov 22 Oct '18

22 Oct '18

Hi, I have a question about RTPEngine set IDs: As of Kamailio 5.x, it appears the RTPEngine module has got quite smart. Even if I don't set `setid_avp`, it still knows which RTPEngine instance and set ID was engaged by an initial rtpengine_offer() / rtpengine_manage() command. This knowledge persists even to delete calls in CANCEL / BYE handling, or in subsequent offer/answer calls in reinvites or UPDATEs. That's great, and very convenient. It saves me the trouble of having to store the set ID in an RR param or as a dialog variable, because everything Just Works. The problem, of course, is that if I restart Kamailio, all this state is forgotten. So, for example, if I set up a call, answer it, restart Kamailio, then hang it up, the delete command will go to the default set and not necessarily the non-zero set chosen. If I want proper RTPEngine call teardown to persist across restarts, as far as I can tell I will need to store the set ID in an RR param or some other reasonably stateless way. Am I missing anything here? Does the `rtpengine` module offer some means of persisting this data across restarts? As far as I can tell, its database backing is for the set definitions only and not for call state.

kamailio + asterisk + webrtc
by arish haque 22 Oct '18

Hi all, I am using kamailio as sip server and asterisk as media server behind pf-sense firewall (NAT) with a public ip. Sip signalling as well as rtp packets are flowing correctly when the endpoints are within a network. But when trying from outside network sip signalling is working perfectly but there is no RTP. Public ip behind pfsense -> 182.70.xx.yy kamailio+rtpengine and asterisk servers are on private ips --> 192.168.1.x kamailio ip - 192.168.1.x asterisk ip - 192.168.1.y Please, feel free to ask for more information. Thanks & Regards, Arish Haque

Kamailio forwarding call via Public IP Address vs Private IP Address
by Wilkins, Steve 21 Oct '18

21 Oct '18

Good morning All, I have two almost Identical (Kamailio=>Asterisk) systems set up, but one of them is receiving calls and forwarding them to the Asterisk Public IP, and the other is Forwarding to the Asterisk Private IP. The call is coming in to the number and domain in both scenarios. Any ideas on what would cause this? Thank you, -Steve

Acoounting with acc_radius when dialog terminates by default_timeout
by Denys Pozniak 19 Oct '18

19 Oct '18

Hello! How can I send RADIUS Accounting-Request in case of terminating dialog via default_timeout timer? I tried to catch Kamailio's own generated BYE in event_route AND tried to use cdr_expired_dlg_enable , but it looks like acc module is not triggered. event_route[dialog:end] { if ( dlg_isflagset(FLT_ACC_START) && is_method("BYE") ) { setflag(FLT_ACC); } dlg_resetflag(FLT_ACC_START); } modparam("acc", "log_flag", FLT_ACC) modparam("acc", "cdr_expired_dlg_enable", 1) modparam("acc_radius", "radius_config", "/etc/radiusclient/radiusclient.conf") modparam("acc_radius", "radius_flag", FLT_ACC) modparam("acc_radius", "radius_missed_flag", FLT_ACCMISSED) modparam("dialog", "default_timeout", 3600) modparam("dialog", "send_bye", 1) version: kamailio 4.4.2 (x86_64/linux) 892ad6 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, 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: 892ad6 compiled on 12:58:38 Aug 28 2017 with gcc 4.8.5 -- BR, Denys Pozniak
