Problem with ghost dialogs
by Cyrille Demaret 28 Feb '19

28 Feb '19

Hi, I'm running Kamailio 5.1.4 and I have some problem with some random dialogs sometimes staying in early state and never ends until I restart Kamailio. According to the init_ts, this dialog is there since 11/01/2019. * Do you have an idea how I can diagnose this problem? * Is there a way to kill these dialogs? I have tried with "dlg.end_dlg" but It seems it's not possible to kill dialogs in early states. { h_entry: 3382 h_id: 4069 call-id: d6e6de79-7d55-486f-889f-01b05c003411 from_uri: sip:0037xxxxxxxxxxx@mydomain.com to_uri: sip:1234@mydomain.com state: 2 start_ts: 0 init_ts: 1547195739 timeout: 0 lifetime: 43200 dflags: 1536 sflags: 0 iflags: 0 caller: { tag: a909d6fa-cee9-44ac-ad76-3697fcd5cb0e contact: sip:asterisk@192.168.102.20:5080;alias=192.168.102.20~5080~1 cseq: 7362 route_set: socket: udp:192.168.102.10:5060 } callee: { tag: contact: cseq: route_set: socket: } profiles: { { caller: sip:0037xxxxxxxxxxx@mydomain.com } { callee: sip:1234@mydomain.com } } variables: { } } Thank you for your help.

Is DMQ now the recommended way to do things?
by Canuck . 21 Feb '19

21 Feb '19

Before DMQ there were other ways to do similar things. Is DMQ now considered the best way? Assuming I am using recent stable? Are there any good guides on clustering Kamailio? I am not finding a lot of good info on that subject. Specifically, for multi datacenter active active where things like floating IP's and keepalived are not really an option.

how to differentiate branches in parallel call forking
by Koray Vatansever 09 Feb '19

09 Feb '19

Hi, I'm trying to implement parallel call forking scenario. Since target clients have different media profiles, I need to set different rtpengine options for those forked calls. So according to the rtpengine module documentation, I set via-branch option on request and response, '1' and '2' respectively ('auto' option is not working. There is no code implementing this parameter). However all forked branches have the same via branch id which is the incoming INVITE's via branch id. As a result, rtpengine thinks that all the offers belong to the same session I guess. It seems I have only 'extra' option with extra_pv_id variable. In order to use it, I need an elegant way to differentiate forked branches in request and response processing. I would appreciate any suggestion.

Planning Fosdem 2019
by Daniel-Constantin Mierla 02 Feb '19

02 Feb '19

Hello, Fosdem 2019 is approaching, so I am writing to see if any of you plans to go to the event. If there is interest, we can try to organize again a dinner on Saturday evening, a tradition for our project at the past 10 editions or even more. Henning Westerholt will give a presentation about Kamailio in the RTC Devroom, I will be around as well. I know few more developers that plan to go to the event, so let's see who else from the community wants to join us. As usual, at Fosdem will be developers from other VoIP projects, like Asterisk, Janus, CGRates, Homer, Jitsi, ... At the past editions we typically had two "kamailio" events: 1) an "ad-hoc" developers meeting in the cantina (or other available room around) to discuss about short term plans for Kamailio -- time and place being decided as we meet there between us (expected in the afternoon of Saturday or during Sunday). 2) a dinner at a place nearby, with other VoIP folks joining us Reply if you plan to go to Fosdem and say if you want to join for a dinner. Just be aware that you have to pay for your food and drinks at the dinner, unless we are going to be surprised again by a generous sponsor that covers partially or completely to dinner. If you need more details about Fosdem, the website is: - https://fosdem.org Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference - May 6-8, 2019 -- www.kamailioworld.com Kamailio Advanced Training - Mar 4-6, 2019 in Berlin; Mar 25-27, 2019, in Washington, DC, USA -- www.asipto.com

dispatcher alg - 8
by Andrew Chen 31 Jan '19

31 Jan '19

Hey all, I need some more clarification on dispatcher alg 8: “8” - use first destination (good for failover). What is meant by "first destination"? How is that defined if I have more than one carrier. More specifically in our case for some PSTN locations we have this setup: primary carrier - 1 sip trunk backup carrier - 4 sip trunks or primary carrier - 4 sip trunks backup carrier - 1 sip trunk the one that have 4 sip trunks is it going to round-robin through it? this is setup on our old 4.1.5 release. thanks -- Andy Chen achen@ <achen(a)thinkingphones.com>fuze.com -- *Confidentiality Notice: The information contained in this e-mail and any attachments may be confidential.

IMS early media
by Tsvetan Filev 31 Jan '19

31 Jan '19

Hi all. I want to use SIP early media to play music to the caller in kamailio IMS installation like this: http://www.sharetechnote.com/html/IMS_SIP_EarlyMedia.html I looked a little bit but didn't find ready solution. The information is vague on this topic. Should this be done through a module or application server ? May I need to handle ringing in onreply_route and send OK with SDP to the caller in SCSCF ? Regards.
