Having trouble getting presence working with Polycom VVX phones
by Justin Foley 03 Jul '18

03 Jul '18

Hey everyone. I've set up a kamailio server on a local dev box and running the phones on the same subnet as it to avoid any NAT issues. Seems to work fine, phones register & can call eachother and hear voice but the issue I'm running into is I can't seem to get presence to work. I've enabled it in the kamailio.cfg file with #!WITH_PRESENCE but if I go into "do not disturb" or try to call on phone1, it's not indicated on phone2. Also running ngrep on port 5060, I'm not seeing the anything regarding presence being sent over the SIP protocol.

Hi community, So I'm running 4.1.5 Kam version and I wanted to print out $rs variable. It printed out <null> right after the 183 session. Should it print something? What our server side sent is this: INVITE 100 183 488 or 487 And this is the output in kam logs: Jun 28 15:05:49 sjomainfnsg51 /usr/local/sbin/*kamailio*[15215]: INFO: <script>: [4975Fz-ses1-414b02f5R68422169(a)192.168.0.22][2][CSeq 1] fuze_for_mac/99.99.99999 Reply status <null> detected... any thoughts?

linphone & presence_xml ERROR
by Pali Rohár 01 Jul '18

01 Jul '18

Hi! I'm using linphone 3.6.1 as SIP client and Kamailio 4.4.4 as proxy server and registrar. And every time I try to change online status (presence) in linphone client, I see following error messages in kamailio server log: ERROR: presence_xml [add_events.c:167]: xml_publ_handl(): bad body format ERROR: presence [publish.c:443]: handle_publish(): in event specific publish handling ERROR: tm [t_reply.c:533]: _reply_light(): ERROR: _reply_light: can't generate 500 reply when a final 415 was sent out ERROR: sl [sl.c:269]: send_reply(): failed to reply stateful (tm) ERROR: presence [utils_func.c:146]: send_error_reply(): sending 500 Server Internal Error reply ERROR: presence [publish.c:492]: handle_publish(): failed to send error reply So it looks like kamailio is not able to parse presence change which is linphone doing.

Maybe it helps you. Any idea why kamailio refuse presence update and reports those error into error log? Or is there any special setting which is needed for linphone or other SIP clients for online status / presence support? -- Pali Rohár pali.rohar(a)gmail.com

dovecot authentication
by Pali Rohár 30 Jun '18

30 Jun '18

Hi! Is there any module or configuration how to use dovecot SASL authentication in Kamailio? Dovecot exports unix socket (or tcp on localhost) for authentication service and lot of server applications can be configured to use it (e.g. postfix, prosody, ...) to have one central place of user and authentication database. It supports also strong authentication schemas like SCRAM-SHA, but also plain text password or DIGEST-MD5. In SIP is used DIGEST-MD5 therefore it could be suitable also for SIP and Kamailio. -- Pali Rohár pali.rohar(a)gmail.com
