Hi, Here is a simpler easiler solution for your case. Prerequisits: 1. Media gateways should register for somewhat longer period of time, e.g. 3600 seconds (shorter intervals would work too but longer is better). 2. All media gateways should register to kamailio through same kamailio listen socket (if they register through different kamailio sockets then it would add further complication since then you have to manage forced socket too in dispatcher module). Method: 1. Enable dispatcher module with db backend. https://kamailio.org/docs/modules/5.0.x/modules/dispatcher.html#dispatcher.… 2. Enable received_avp in registrar module, (you can work without it but then you need to create and manage received avp yourself). https://kamailio.org/docs/modules/5.0.x/modules/registrar.html#registrar.p.… 3. When any media gateway registers with kamailio successfully. You should have received_avp filled up. Use SQLOps module to insert this in dispatcher module. 4. Reload dispatcher db, https://kamailio.org/docs/modules/5.0.x/modules/dispatcher.html#dispatcher.… Now you have a working load balancing setup for your MGs valid till their sip register expiry. You can choose whatever load balancing algorithm you like. 5. For media gateway re-register, step 4 & 5 are not required. 6. When any media gateway un-registers or registration expires, remove the entry in dispatcher table and reload. https://kamailio.org/docs/modules/5.0.x/modules/registrar.html#idp23888404 Hope this helps.
