There are Python bindings for PJSUA (simplified UA wrapper, part of PJSIP)... -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Hello, Your question is about how to send customized PUBLISH to Kamailio? Anton On Mar 30, 2016 21:22, "Igor Olhovskiy" <igorolhovskiy(a)gmail.com> wrote:

Hi, all Not a Kamailio-related question, but. I want to form SIP-packets with info I need and receive answers. At first iteration in would be PUBLISH (with XML info) messages (PUBLISH - 200 OK) sent to Kamailio. I want to use Python (more preferable) or Lua (less preferable). Is there any lib I can create messages with, or forget and just use plain text + UDP socket? -- Best regards, Igor _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

With uac_req_send() I need to have Kamailio installed just to send message ;) Overkill a bit. But thanks :) 2016-03-30 22:47 GMT+03:00 Igor Olhovskiy <igorolhovskiy(a)gmail.com>om>:

Yeah, I know. But look how easy - seductively easy. :) --- function LRNquery(tn, req, res) { sip.send({ method: 'INVITE', uri: 'sip:' + tn + '@208.52.173.7:5062', version: '2.0', headers: { from: { name: 'node', uri: 'sip:node@172.30.106.108:5060', params: { tag: 'abcxyz123444' } }, to: { name: 'redirect', uri: 'sip:redirect@208.52.173.7:5062', params: {} }, 'call-id': '9995551232344523(a)172.30.106.108'108', cseq: { seq: 1, method: 'INVITE' }, contact: [ { name: undefined, uri: 'sip:node@172.30.106.108:5081', params: {} } ] } }, function(rs) { if(rs.status == 302 && 'headers' in rs && 'contact' in rs.headers && rs.headers.contact.length > 0) { var contact = rs.headers.contact.shift(); var lrn = contact.uri.match(/rn=(\d+)/); if(lrn) { res.writeHead(200, 'OK', { 'Content-Length': lrn[1].length }); res.end(lrn[1]); return; } } res.writeHead(500, 'Internal Server Error'); res.end(); }); } -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

You can probably use the sipp tool. It is more for load testing but you can easily create messages. 2016-03-30 22:00 GMT+02:00 Igor Olhovskiy <igorolhovskiy(a)gmail.com>om>:

- then why are you asking this on kamailio mailing list? :) I know here are many SIP-developers. Question about SIP, and receiver of this message would be Kamailio :) 2016-03-30 22:52 GMT+03:00 Alex Balashov <abalashov(a)evaristesys.com>om>:

Hello, to add a bit more to the suggestions offered by the others ... if you have the sip packet in a file, you can send it over with protoshoot (included in kamailio at utils/protoshoot/). Maybe more useful will be sipsak, it allows to do a lot of sip stuff from command line -- this should be packaged on most linux distros, if not, it is hosted on github by the author Nils Olhmeier: * https://github.com/nils-ohlmeier/sipsak If you need to send over websocket, a while ago I wrote a small tool in go - wsctl: * https://github.com/miconda/wsctl Cheers, Daniel On 30/03/16 21:21, Igor Olhovskiy wrote:
