Hi Guys,

I have 2 kamailio servers. I need to load balancing for this 2 kamailio servers. Scenario:

---

Each kamailio server call limit is 5000 approx. kamailio server 1 kamailio server 2 If kamailio server 1 reach call limit (5000) then call go on kamailio server 2.

What is the best way for achieve this?

A workaround could be kamailio-1 to manage the total of dialogs (by using dialog module) and reply a 302 with a header "Contact: sip:ORIGINAL_RURI_USERNAME@IP_KAMAILIO_2" when the number of dialog is 5000 or greater. Then the clients would repeat the call to the second kamailio. This won't work in case the clients have configured kamailio-1 as outbound-proxy as they would remain sending the second INVITE to the same kamailio-1.

A more clean design would involve a stataless balanding proxy in front of both kamailio-1 and kamailio-2.
