failure route is not executed when suspended invite is cancelled
by Koray Vatansever 24 Dec '18

24 Dec '18

Hi all, I'm trying to upgrade kamailio from 4.2.7 to 5.1.5 and I realized that when CANCEL is received for a suspended INVITE, failure route is not executed in release 5.1.5. In 4.2.7 failure route is executed for this scenario. Is this the expected behaviour or am I missing something?

DTLS HA redis-pacemaker-corosync
by Жан Базаров 10 Dec '18

10 Dec '18

Hello! Are there any ways to implement using DTLS in redis HA scenario? When I reboot the active RTPEngine server the system correctly fails over to the other server and, after only a small pause (~1s), incoming audio continues to arrive. However, approximately 15 seconds after this I hear nothing but silence. Thanks.

SIP SIMPLE TO XMPP AND VICE VERSA
by sagar malam 08 Dec '18

08 Dec '18

Hello, We have a system which using FreeSWITCH for calls and Ejabberd( XMPP) for chat.Now we want to support SIP SIMPLE as well.But we are not going to move old users to SIP SIMPLE but only new users will use SIP SIMPLE.This leads to requirement of having SIP-XMPP gateway for which are are considering Kamailio server. I have gone through documentation about Kamailio XMPP module, it is clear that Kamailio can convert SIP MESSAGE to XMPP so SIP to XMPP will work but what about XMPP to SIP MESSAGE ? Does that work as well ? Thanks in advance. -- Thanks, Sagar

presence/mwi issue
by Andreas Granig 04 Dec '18

04 Dec '18

Hi, Currently playing with presence_mwi in kamailio 5.1, and it appears the issue reported by Juha two years ago at https://lists.kamailio.org//pipermail/sr-dev/2016-September/036609.html seems to have appeared again somewhere along the way. I’m sending a PUBLISH with message-summary event type, however I’m getting this error: ERROR: presence [presentity.c:283]: check_if_dialog(): failed to parse xml document As said in the old thread, it’s not an XML document, so it shouldn’t try to treat it as such. Any ideas? Best, Andreas

Dispatcher with a naptr address as destination
by José Seabra 04 Dec '18

04 Dec '18

Hello all, I'm trying to use a naptr address as a dispatcher destination and i'm facing some issues here. When i configure a naptr address in dispatcher table, like: *1:1:sip\:proxy-registrar-ci1.fuze.domain:0:0:'':''* I see kamailio making a dns query of type A, but since that this name doesn't have any A record configured in dns, kamailio didn't get any positive reply from it. Should't kamailio make dns query by this order? 1. NAPTR 2. SRV 3. A I noticed also that if the name configured in dispatcher table is resolved successfully with A record from dns, then kamailio tries to make a query to NAPTR and then SRV services for the exactly same name used for query previously done(type A), but only if it gets a positive answer from dns to the A type query. I'm using kamailio version 5.1.0 with the following dns parameters configured: ####### DNS Parameters ######### dns = no rev_dns = no dns_try_ipv6 = no dns_retr_time = 1 dns_retr_no = 1 dns_cache_del_nonexp = no dns_cache_flags = 1 dns_cache_gc_interval = 120 dns_cache_init = 1 dns_cache_mem = 1000 dns_cache_negative_ttl = 60 dns_try_naptr = yes use_dns_cache = on use_dns_failover = on dns_srv_lb = yes Is there something wrongly configured here that can make kamailio behaves like that? Thank you. Regards -- Cumprimentos José Seabra
