Hi Daniel, Thanks for you answer On Tue, Mar 07, 2017 at 11:35:17PM +0100, Daniel-Constantin Mierla wrote: My idea is to expose a set of API functions, allowing other modules to register/unregister addresses to monitor. So yes, destinations adresses would be duplicated in keepalive module memory. Then keepalive module would notify the "source" module when destination status change (available -> unavailable, and vice-versa) I have started working on a POC. It is available at https://github.com/gbour/kamailio/tree/module-keepalive
