Lost of connection with MySQL?
by Igor Potjevlesch 02 Mar '17

02 Mar '17

Hello, Two times in the last week, Kamailio reports MySQL errors like these: /usr/local/sbin/kamailio[19225]: ERROR: db_mysql [km_dbase.c:126]: db_mysql_submit_query(): driver error on query: Can't connect to MySQL server on '192.168.2.6' (4) (2003) /usr/local/sbin/kamailio[19225]: ERROR: <core> [db_query.c:235]: db_do_insert_cmd(): error while submitting query /usr/local/sbin/kamailio[19225]: ERROR: acc [acc.c:504]: acc_db_request(): failed to insert into database These errors are repeated many times and cause Kamailio to hang and don't reply to SIP requests. A reboot of Kamailio solves the issue. Anyone has already had this issue and had solved it?

CentOS 6 RPMs don't provide utils.so nor http_client.so
by Trevor Peirce 01 Mar '17

01 Mar '17

Hello, Is there any reason the CentOS 6 RPMs don't build utils.so or http_client.so? Looking back to 4.3 it appears it was being built: kamailio-utils-4.3.6-1.1.x86_64.rpm However it is no longer available in 4.4 nor 5.0 RPMs for either CentOS 6 or 7. Thanks, -- Trevor Peirce AcroVoice Solutions Inc

by José Seabra 01 Mar '17

01 Mar '17

Hello there, Some times dns server fails and my kamailio server start replying "Unresolvable destination (478/SL)". The propose of my email is to know if is there any possibility to change this reply (478) to for example one of 5XX replies. I have modparam("sl", "default_code", 503) but in situations where dns fails, kamailio doesn't reply 503. Thank you for your support Regards José Seabra

sip over websockets sip uri
by Jade SZ 28 Feb '17

28 Feb '17

Hi Team, Question: Just wanted to clarify regarding SIP URI in webrtc (over sip) connection. e.g. if we have a scenario where Kamailio is hosted with websocket support. Websocket URI is used to send packets to to wss/ws address and the SIP URI goes with it. I have tested it with any SIP URI including any domain and it works if I authenticate that domain, regardless that domain is real or not. // client side SIP URI config var configuration = { uri : 'sip:alice@example.com', }; Can we use any central domain for sip uri similar to realm concept and send traffic to multiple kamailio servers through websocket LB. dummy.domain - for ws/wss SIP URI kamailio-a.domain.com kamailio-b.domain.com Thanks in advance. Regards, Jade

Newbie starting - looking for docs / tutorials
by Antony Stone 28 Feb '17

Hi. I'm just starting with Kamailio - I've been to a few presentations about it, at Fosdem and KamailioWorld, but never used it so far. I'm pretty familiar with Asterisk, and I want to use them in combination. My first use case is to handle SIP registrations (both as a client, registering to a remote SIP server, and as a server, accepting registrations from handsets) in Kamailio instead of Asterisk, and still be able to route calls to/from the registered accounts through the Asterisk dialplan. I suspect this is a pretty common starting point for people who've used Asterisk and want to add Kamailio to the setup? So far I've been unsuccessful finding any Howto or Tutorial explaining how to do this - I can't help feeling I must simply be looking in the wrong place or in the wrong way. Searching for topics like "Asterisk Kamailio Getting Started" I find: http://kamailio.org/docs/ser-getting-started/SER-GettingStarted.pdf but with 12 chapters and 85 pages I'm not sure which bits are the essential parts to do what I need. I've also found http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x- asterisk-11.3.0-astdb but this seems to focus on a database backend, which I guess I'll want to use in due course, but doesn't seem the simplest place to start just to learn how Asterisk & Kamailio work together? So, please can someone suggest a beginner's guide to introducing Kamailio into an Asterisk setup, keeping things as simple as possible to start with, so I can learn about Kamailio one bit at a time (since there do seem to be a lot of bits to it) from a familiar environment of using it with Asterisk? Thanks in advance, Antony. -- What do you get when you cross a joke with a rhetorical question? Please reply to the list; please *don't* CC me.
