[SR-Users] What happens to calls when Kamailio restarts?

Hi, I have a question regarding calls and Kamailio restarts. Suppose Kamailio crashes (and started again), is restarted or failed over to a different server (same IP). What then happens with calls? Let's suppose the following scenario: - 1000 calls active on the machine - Some are in call setup, some are in call, some are in teardown phases - The proxy is stateful - The proxy forwards calls from B2BUA machines to an ITSP (outbound only) - Uses record-routing - Uses loose routing What will be the likely outcome of the restart with regards to the calls in the different phases and accounting for said calls? All the best, Samuel
