UDP send: Operation not permitted
by Sebastian Damm 11 Mar '16

11 Mar '16

Hi, we have a load balancer which is handling a lot of SIP traffic all day. There's always 20-40 Mbit SIP traffic going through. From time to time we see in our logs messages like these: Sep 16 09:46:28 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1321,0,46.237.225.126:5060,16): Operation not permitted(1) Sep 16 09:46:38 ecker /usr/sbin/kamailio[25194]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982b8fc8,420,0,82.113.121.183:35794,16): Operation not permitted(1) Sep 16 09:46:40 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1338,0,5.158.137.9:55067,16): Operation not permitted(1) Sep 16 09:46:44 ecker /usr/sbin/kamailio[25183]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982d9f48,450,0,178.165.131.197:37515,16): Operation not permitted(1) Sep 16 09:46:49 ecker /usr/sbin/kamailio[25643]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f93fb624530,496,0,172.56.7.69:25643,16): Operation not permitted(1) Sep 16 09:46:55 ecker /usr/sbin/kamailio[25335]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632cda98,598,0,80.215.234.139:3396,16): Operation not permitted(1) Sep 16 09:46:56 ecker /usr/sbin/kamailio[25345]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632f4840,459,0,94.197.120.191:8225,16): Operation not permitted(1) I know that these messages can be produced by iptables blocking the outbound traffic. But our outbound chain looks basically like this: root@ecker:~# iptables-save | grep OUTPUT :OUTPUT DROP [0:0] -A OUTPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -j ACCEPT -A OUTPUT -m state --state INVALID -j DROP -A OUTPUT -o lo -m state --state NEW -j ACCEPT -A OUTPUT -o lo -j ACCEPT -A OUTPUT -m state --state NEW -j ACCEPT We don't have the nf_ct_sip module loaded, syslog doesn't say anything, and even clearing all iptables rules doesn't eliminate those errors. Has anyone ever seen this? It looks like a load thing, because at weekends there are significantly less errors. Thanks, Sebastian

Append to reply in default action of failure_route
by Efelin Novak 28 Dec '15

28 Dec '15

Hi, I would like to append a header to a 'winning' negative reply in failure_route and let the Kamailio do the default action (state fully forward the winning reply). When I use append_to_reply("Foo: bar\r\n"); and then call exit; in failure_route nothing is appended. When I use same append_to_reply then t_relay("505","Error"); and exit; the header is appended. When I use append and t_reply with dialog modul turned on I got a bug I'm solving here '[SR-Users] t_reply in failure route with dialog module'. So my question is how to put a header into a reply when I don't want to alter its code or text? I'm using Kamilio 4.0.4 on Debian 7.1 Thanks for an answer Efelin

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

Kamailio IMS - VM
by Bruno Cruz 17 Nov '15

17 Nov '15

Hello everyone, My name is Bruno, I'm a student from Portugal studying IMS at the moment. I've been following tutorials online, trying to get Kamailio to work as an IMS core - I'm pretty much a newbie in this field. Unfortunantly I've been getting several errors and I can't seem to properly configure everything. I was wondering if there is a All-in-One VM that can be downloaded, with Kamailio ready to be used as an IMS core? Thanks in advance. Best regards, Bruno C.

Hi all, I need to modify the host part of a contact header. I'm trying something like: route { ..... if (remove_hf("Contact")){ if (insert_hf("Contact: rn", "Contact")) xlog("Contact modified"); } if (!t_relay("YYY.YYY.YYY.YYY","5060")) { sl_reply_error(); } ...... } When i look SIP DUMP on YYY.YYY.YYY.YYY side i see older Contact field. I try subst_hf with regexp, subst and simply remove Contact, all this does not work. What i am doing wrong? -- С уважением Зуев Михаил
