Hello Benoit, the current stable branches 5.3. and 5.4 only receiving bugfixes and similar changes after release, this our current release policy. You could ask one of the companies providing commercial services to Kamailio e.g., from this list https://www.kamailio.org/w/business-directory/ for providing you with a custom backport of the module. Of course you can also investigate it by yourself. Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; On Behalf Of Benoit Chesneau Sent: Thursday, December 10, 2020 1:53 PM To: sr-users(a)lists.kamailio.org Subject: [SR-Users] porting keepalive module new functions on 5.4 on 5.3? 2 new functions have been added to the keepalive module: · ka_add_destination(sip_uri, owner)<https://kamailio.org/docs/modules/5.4.x/modules/keepalive.html#ke… · ka_del_destination(sip_uri, owner)<https://kamailio.org/docs/modules/5.4.x/modules/keepalive.html#ke… Is there any possibility to do the same on 5.3? It seems that on 5.3 adding a destination can only be done statically: https://kamailio.org/docs/modules/5.3.x/modules/keepalive.html#idm53 or can it also be done dynamically when receiving an event using the kazoo module for example?
