Hi everybody, I'm just testing Kamailio 5.4.1 with dialog replication over DMQ. This seems to work very good. Dialogs are replicated without problems. When I'm restarting one node I would have expected, that all dialogs are synced again, just like in dmq_usrloc. But this does not happen. After a restart the nodes dialog-list is empty. Did I miss somethin? Is there a special parameter that I have to set?

Is Min-SE check broken?

by harneet singh

Hi All, I am facing an issue in understanding how the min_se should be working in kamailio. As per the SST documentation, it seems like if the min_se is configured as 500, then any value of Session-Expires OR MIN-SE if lower than 500, can be responded to by a 422. However, I strangely see the reverse happening. To investigate further, I looked in to the ki_sst_check_min() code in the master, and these seems like a potential issue. Ref Code: Inside ki_sst_check_min(), there is an if condition like below: if (sst_min_se < MIN(minse, se.interval)) { However, shouldn't it be the other way around? ie if (sst_min_se > MIN(minse, se.interval)) { because we need to send 422 if the received value(in INVITE etc) is smaller than the sst configure min_se value? I also found a different documentation, at https://git.sgu.ru/oldssu/ex-opensips/blob/cb9df8d59dbb254a9d862569fd5d11f6… where the check is as below? if (sst_min_se > MIN(minse, se.interval)) { Can someone confirm if this is broken, or my understanding is incorrect?

Config works fine with mysql as topos backend. So the bug is restricted to topos-redis.

enable topology hiding on one side or dynamic ip in topoh module Contact and Via Header

by Patrick Karton

Hello , im using kamailio with two interfaces external and internal. i need a way either to : * enable topoh hiding only when outgoing interface is external ( mask contact and Via ip only when ougoing interface is external * or if it is not possible to enable it only in one direction.i want to know how to configure dynamic(for example in xavp or avp) ip to put in Contact and Via when topoh is enabled. i see that the 'mask_ip' parameter of topoh module is a string. so we can not set a dynamic value here unfortunately. Thanks

kamcmd autocompletion

by Antoine DEBARRE

Hi, I just installed kamailio v5.5 via deb.kamailio.org packages (debian 11). Seems that kamcmd autocompletion doesn't work at all. It is OK for v5.4 via official debian packages (packages.debian.org/bullseye/kamailio) Best regards, -- <https://app.livestorm.co/comdata-group/metaverse-what-will-cx-look-like-in-…>

Possibility of mirroring the rpm/deb.kamailio.org repos efficiently via rsync?

by Malte Schmidt

Hello, is there an rsync endpoint available or is there a possiblity of setting this up? Creating a mirror via HTTP is a rather quick and dirty solution and while the deb-repo can be mirrored using debmirror, the rpm repo is hard to sync to a non-CentOS-based machine due to missing dependencies such as yum and reposync in latest Debian-based systems. Would be great to get some input in regards to this topic. Cheers

Kamailio vs FreeSWITCH as SBC

by Unai Rodriguez

Dear List, I’m looking at using Kamailio as SBC. This would replace our current FreeSWITCH-based SBCs. What are your thoughts on this move? Would there be any known reasons why Kamailio would be superior to FreeSWITCH as an SBC? Thank you so much Unai Rodriguez

SNMP, export concurrent calls count

by ZZ Wave

Hello. Debian 10, Kamailio 5.2.1 I want to monitor concurrent calls in/out per every trunk connected to this proxy (it's done with dialog profiles), and export this to Zabbix. But I can't find in snmpstats documentation how to export user-defined variables. Help me please. Maybe SNMP isn't the best solution for that...
