Hello Peter, Sorry for my ignorance, but I could not get the point when you say "You will hit Linux limits fairly quickly if you try to source calls from different IP addresses or ports". Calls from one sipp instance can be sourced with different ports but IP has to be same , how can they be sourced from different IPs ? Thanks Merlin
