Hi Henning, I agree that it shouldn't be a problem to a downstream server however I was hoping to have a cleaner solution. we are deploying Kamailio in containers and have total of 4 so far for high availability, so don't want to fire pings at the downstream and also would generate unwanted logs.

This would be surely the simplest solution. The few pings every minute or so should not be an issue to any server.

One option is to make another set, however that will force Kamailio to send ping (OPTIONS) twice when probing. Regards, Adarsh Chauhan
