In our case we will have an autoscaling system of Kamailio based on geographic requests and load so we will not be able to know in advance how many instances ok kamailio will be provisioned. As you suggested for this temporary workaround we should have : Server 1 : 1, 101,201,301,401... Server 2 : 2, 202,302,402,.... Server n : n, n+100,n+200,n+300,...
Where n < 100
