Thank you for the responses! As a follow up question, how do companies with large loads on their Kamailios handle restarts especially considering the CANCELs?
What is a good (business) process to restart a Kamailio without incurring any interruptions at all? What other components in the infrastructure would be in place and which ones are in use in the wild? // Samuel ________________________________ From: sr-users <[email protected]> on behalf of Sebastian Damm <[email protected]> Sent: Thursday, July 13, 2017 2:39:39 PM To: Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] What happens to calls when Kamailio restarts?

There's one thing that could happen: Calls that get cancelled after a restart, could possibly keep on ringing on the far end. At least if you check for an active transaction in your kamailio config. if (!t_check_trans()) { sl_send_reply("481", "Call/Transaction does not exist"); xlog("L_ERR", "CANCEL: found no matching transaction F=$fu T=$tu R=$ru\n"); return; } And if you do some sort of random dispatching, CANCELs could end up on a different gateway. But other than that, a restart shouldn't cause much trouble. Especially in-call requests get routed by Route headers only.
